At last! Someone who can explain this to me w/o all the technical jargon where you need a degree just to understand it. Simple sit down, plain to earth talk where everybody can understand it. Thank you sir, catch you on the flip.
Really? 13 year old me figured this out in the late 70's without needing a hand holding video or the internet.
@@sahhull Good for lil ol you... Want a cookie?
i dont mean to be so off topic but does anyone know a method to get back into an instagram account??
I stupidly forgot the password. I would appreciate any assistance you can offer me
@Holden Barrett instablaster =)
REALLY? Tuning an antenna is too difficult to understand? And you have a driver's license?
BleepinJeep, here it is 9, maybe 10 years later? And after CB'ing since the 80's I find this the most useful tuning video I've seen.
Very useful info. Bought a new radio for my truck to replace the 80s cb radio and had no idea about tuning. When I tested it was way maxed. This video and a Firestick II antennae let me get it under 1.5 in under 4 minutes of climbing on and off the catwalk.
Finally someone who actually understands what they are doing. I can't believe how many people don't understand cable length. Only thing you forgot was grounding the antenna. As a veteran cb user of over 20 years you are dead right on this and get job explaining.
how do u ground it when u only have a coax wire
@@derricksmiley5632 you run a ground strap from the antenna is located
When the antenna is mounted typically the bracket to a grounding point in the vehicle.
I've drove truck now for 20 years and you my friend tought me something new today thank you.
This has to be, hands down, the most informative CB tuning video on youtube. excellent visuals, examples, and explanation. Helps me a lot, I'm new getting into CB.
Finally......Simple, To the Point with Actual Graphics - All you need to know in 7 minutes - It just doesn't get any better than this......Thanks!!
thank you for taking me back to before I had internet and I used to spend hours talking on my base station.
I wish I still had my base station.
if power goes down and cell service is disrupted they will wish they knew what a CB is
Your right .
When the grid goes down , only c.b,s will work . But by then it will be to late for them to understand a c.b.
How would you power a CB if the grid goes? If things get that bad, you better believe your gonna be out of fuel for vehicles in under a couple weeks too unless you stockpile fuel, which only makes you a high value target.
Daniel T using a car battery
This is so true. That's why the Gov't will never get rid of 11 meter CB spectrum because there are millions of new and old CB's out there, and if SHTF happens, people will use those radios to keep communications going.
@@33rdGemini CB doesn't need fuel It needs a car battery ...Millions of them laying around if grid go's And all of them cars that you say will only last a couple of weeks will be littered all over the streets ..However As history as shown after 3 days of a east coast black out People resorted to other means of fueling ..My city police / fire /medical service Poured fuel manually into cars and trucks From city storage that has a resevre for Salt trucks The same hand pump can be bought at a few stores HD ones.
You would not be a high value target if people don't see your cans inside your truck And you were smarter then sticking around to get to that point ...Really if you get to a point Nothing will save you from a total disaster The Idea of a CB is having one more form to keep in touch with the outside ..You cell phone dies, forgot it at home, bad or no reception ..You break down in the middle of a side road 20 miles from the main road in the Canadian north during winter Where skin freezes in mins. No signal Your going to want a CB or a Skidoo in the back ...
Hell, thats the same spring and whip I had back in the early 90s. Perfectly measured coax would make a Cobra 19+ sound like a champ!
Great info. I have wanted a Jeep Wrangler since I started driving. For a myriad of reasons, including 3 kids, I have never had one until I bought a 2004 Tj about 6 months ago. It was a very plain jane TJ, which was what I wanted so that I could build it out the way I wanted it. I have put on a 2 inch Rough Country Lift and Leveling kit, bought new black wheels and new General Grabber AT2 tires. I have a whole bunch of other parts for the interior and exterior that I will be putting on and in over the next month or so, one of them being a CB radio and a Firestick antennae. The antennae top has a built in tuner. I had NO IDEA that I needed to tune the antennae. In fact I didn't know it was needed. Thanks for this video. You made it easy for an old fart to understand. I have subscribed to your channel. Thanks again!!!
While I am thinking about it, if you make a custom bracket for the antenna stud, The hole must be 1/2in to Accommodate the isolation washer’s shoulder. This little gem of information has not been mentioned before.
I'm in NYC, so SWR adjustments can be tricky and especially for a home base station. I used a similar 102 inch stainless steel whip antenna for yearsssss, and with that very same styled spring mount but window sided. Yes, out my bedroom window, up high in a public housing project building, mounted onto a window guard, straight out as possible. Hardly any SWR reading whatsoever. Powering the antenna was a RANGER 2970 (the one with the built in cookie/linear underneath), some monster coax cable, a huge Pyramid power supply, and an Astatic tear drop & lollipop mic. I was killing it as far as both reception and transmission distance. But sadly I was also ruining tv and radio reception for hundreds in my antenna's path. The antenna was holding its own just fine after 10+ years of hanging out there, with the spring coil showing a little sign of rust. In my car I used a Cherokee mobile handheld and a Wilson magnet mount. Both worked great. But like most non professional drivers I eventually succumbed to the cell/smart phone and internet while fading away from CB. Great times indeed.
your not countryif you havent sat around on the holidays and played with a CB RADIO. bc its all you got or a good source of clean old fun.. good times i remember calling out my uncle on christmas . where you at BUD MAN ..
Great info, only thing I'll add is wire length Cable must be cut at 3 foot intervals 9 foot instead of 10, is what they taught me first round with radios in 1989
Great video very informative yet simple! Love the camo paint job.
Thanks.. I went through 5 silly ass videos that went on and on about all sorts of other crap.. One even had some clown with gd rap music blaring. Smh.. Thanks for the good and informative video.
A split ring locking washer and flat fender washer is for stopping the assembly from unthreading. If you need to change height, you can add more flat washers, but don't misunderstand basic assembly.
This video is proof that people in the late 1970's early 80's were smarter than the current crop.
13 year old me figured this out, without being hand held thru the process with a video or the internet.
Very helpful video I had no idea how to properly use my cB now is working great thanks to this great video 👍👍👍💯💯💯💯
For real, I listen to him and did it exact as he said and my cb was clear thanks really.
Anyone else now fearful they may have damaged their radio with an SWR higher than 3.0? Lol. I’ll be checking mine when i get one of those devices he mentioned 🤦🏼♂️. Great video! Thanks 😊
I believe the 102 wips are made to be used with the large springs to be the correct length for the cb frequency for low swr.
Yes 102" is made for a spring, 106" is for no spring
@stephen john gray The little ball on the top needs to stay
Thank you very good video learned a lot am a beginner CB user.
great vid man... you have a future doing something besides jeepen
That is a great job. Thank you very much, but you left out one important aspect. You wanna talk into the microphone to make sure the SWR Aren't swinging forward which can also damage the radio mine always used to swing backward.
Great tutorial! I just got an 06 Sierra and I want to put a CB in this bitch for when I take road trips. Mainly for amusement but I'd like to have it if I ever need it. Thanks for the info! Nice Jeep btw.
Gas stations sell SWR meters?
Good info. for us newbies.
Thanks for sharing.
Thank ya
lol I remember how to do that! Yipes,its been a long time!
Great info and awesome video!
OK !!! Remember everyone, do not forget to try to use that Field Strength also !!!! I read a book once that SWR is not the final say in antennas meaurement. V.S.W.R. I once reas in a book means Voltage Standing Wave Ratio. I am not sure, V.S.W.R. might be a text book term or school word and S.W.R. may be a product word. Like, each company has their own way of doing things. 😀
FYI if using the cobra meter you only cal it once on channel 1. Otherwise you get a false positive. The cobra 29 was a jump seat radio to allow drivers to quick set the swr threw the radio instead of ant. Best is to use a swr meter in line. Try to get a .5 to 1 reading on channels 1 and 40.
That's not what the manual says. The manual says channel 20 first, then 40, then 1.
Wish I knew about some of this stuff years ago when farming and still using CB's. Couldn't talk/hear if someone was 2 miles away. There was also so much more static the higher the channels. Most of ours didn't have all those knobs either.
If you’re having trouble hearing it is most likely because they are Having trouble talking. Which means that their antenna is not tuned. The static noise can be eliminated by turning up the squelch knob.
Sometimes a simple radio can be the best for your purposes. You don’t need all of those bells and whistle‘s that some radios have. A 3ft Francis antenna and 18 feet of coax are probably the best plug and play system you can go with. Make a large loop with the extra coax.
I have a Galaxy DX939 and a Stryker 955 HPC and both have self calibrating meters. The meters are not as accurate as a standalone meter, but both of my radios have high SWR warnings and the Stryker will not transmit if the swr is too high. Good protection feature. Most people I know just mount the antenna and don't even tune it and then they wonder why their radio doesn't work.
I have seen those so called Protection Circuits fail & show a High SWR when the SWR was great.They are a reference item just like the builtin SWR Meters at best.
Use this website for information. Read through it. Look for dirty grounds for poor grounds Shorted cables. Broken antennas.
Hey buddy Im getting the same calibration reading on channel 40 as i am on channel 1. Ive got my antenna hooked up correct. I have a wilson trucker 2000 with a hood mount, its grounded. Also i have a Cobra radio with the built in swr meter
Dude ! Thank so much! This information is all I was looking for nothing else. Excellent video ,very professional, no shit ! I'm not knocking guys but oh my God....i went through at least five and i had eject them ....they sucked.....anyway thank you again!
Wow...Very informative. Thanks
The paperwork that came with my SWR meter said to start at channel 20 on a 40 channel radio. calabrate then switch to power and check reading on 20. Without changing anything check swr on channel 1 then on channel 40. adjust antenna length accordingly to acheave as low as possible .
Question!! Indoor antenna in apartment! I dug my cobra 29 digital, with swing , d104 out of storage! Want to get back on air again
Great explanation . You should consider a career in teaching or instruction.
Excellent Video!
Thank you!!!
Quick question, when changing to a different antenna, coax… do I have to re-calibrate the setpoint with the SWR meter? I had a radio hooked up to an antenna on the right side of my truck, bought a totally different kind of antenna to put on the left side of my truck, so I moved my Midland 5001 radio to the left side. hooked upa handheld midland 75-822 to the right antenna, calibrated it with SWR meter.. then went to hook up the STI meter to my radio on the new system on the left side and I couldn’t get the needle to the setpoint it matter how far right I move the knob.. It goes like halfway and start shaking like crazy.
You don’t have to tune, 102 inch well 102 inches as electrical link of 27 Mc which citizen band operates on so if you don’t want to tune antenna, the best one to get is 102 inch whip which is just a little bit over 8 feet
Where did you get your radio? I've been looking everywhere and can't find it.
They’re sold at travel truck stops like Pilot, Love’s, TA, Flying J or Petro. Thats’s were us truckers get ours. Can find it on Amazon, also. Probably sell them at Best Buy
@@apuertorican1773 I both one off ebat but couldn't find a 6 pin mic so I have buy a reducer plug 4pin into a 6 pin
@@apuertorican1773 what's the purpose of it being Bluetooth???
for a old timer (53 years) i learned something, never new washers can make a dif on a 102 tune. also there is feral you can buy with a inch or 2 adjustment. no better antenna then a 102 but a bitch to tune. gota try the washer thing i have about 1.4 on all 40 and want it down lower
good job on the swr
that was great info to know. thanks buddy
Nice work!
Really good video!👍🏾
I never heard Standing Wave Ratio mentioned at all?
Only step you forgot is to turn mic gain down/off so you don't modulate and throw off the cal/reading of SWR.
When I turn my radio on the needle doesn't move at all.. I try to calibrate it on channel 1 but the needle isn't moving.
Love the spelling of your title
Nice Jeep!
😀👍🏿Great Tips,Good Stuff
The meter in ghe radio is the best to use it is more accurate because its not reading the pigtail you use only during the test.
BS.Anybody who knows anything about proper SWR reading knows that is Total BS any day of the week.
I was a tech fir many years made a living in electronics repair much of my work was on ce and amateur equipment. Hows that for your bullshit. Read a damn book.
Well I am a tech in the industry and I agree with 10FGODSOWN.
BS. Never trust those meters until you can compare it to a good quality SWR meter.
Great job Sean!
Cool truck...
Well stated, good info.
Thanks for your help Amigo
Thank You that’s a great video
When i switch mine to cal the swr meter is all over the place. What could be the problem?
Got my CB in.
1.2 swr. I'm good. This is on a base station antenna..50 feet up.
Love your truck
He uses the Trucker Channel for talking to his buddies while on the trails? I guess it works but just a warning, Using Channel 19 for beyond trucking stuff may not always be welcomed. Unless he is that far off the grid away from regular roads, then in that case, their transmission shouldn't be able to be picked up by normal average CB radios.
Hey Paul 223 that tuned escort car 🚗
great video
Would this fit in a DIN slot? I have looked for dimension specifications, and I've found 3 different ones. Could I get an actual measurement of the radio?
most cb radios will not fit in a single din slot on a 4 wheel vehicle but if it's a 1.5 din it will a cobra 18 or 25 will fit into a din but it's better for the radio unless it's purpose built to be exposed like he mounted his to help keep the internals cool
I have an motorhome that has a fiberglass body shell. It has a high mounted fiberglass rod antenna stick that is grounded to the chassis. The SWR readings are pegged. I was told to shorten the antenna cable but got no better readings. Any suggestions when I get a friend's meter to get readings to adjust it?
The antenna base needs to be mounted on something metal; a bumper, a mirror mount, ladder, toolbox, etc. It needs a metal base or "ground plane" to work properly, just running a ground wire from the mount to the chassis isn't enough. Also pay attention to how the mount is set up and you have the insulating washer in the right place.
+Cheezy Dee you can use a ground plane antenna and mount it on the side of the house and also you can just run a wire for ground but it would need to be a big one😉😉😉
Like I said but a ground plain or like cheesy said mount to a mirror or something metal that is grounded to the frame
Buy a 1/2 wave antenna if all else fails since a 1/2 wave antenna does NOT require a ground plane & the mounting location does NOT change the radiating pattern either.
I have a dual 4 foot set up on my truck. We grounded the antennas to the frame and tested it. The swrs for both were way into the red. We used a single CB cable and tested both separate from the other. However when we hooked both together using the co-phase cable, i got readings of 1.5 on both channels. Any help would be great. Do you think the meter I bought was bad?
Habeas J from what I know dual antennas need to be at least 8' apart so they don't fight each other.
Only One SWR.No such thing as SWR's & why they do NOT sell SWR's meters just SWR Meters.
thanks for your helpful video but I have a question I tune my antenna whit the build in swr meter with the engine off it was hi 2.5 on chanel 40 1.5 in chanel 1 but when I turned my engine on all jump to 3 . something what can I do?
Doors open or closed. Try it with the doors closed. See if that makes a difference.
When your engine is on the radio puts out more so you have to set the calibrate again
Much appreciated
102 inch whip antenna are pre tune if u have bad swr because u have bad ground it should be on the cab or the body. then if u still have bad swr u change the length of of the coax, 1.2 is very high still u want .1 or flat swr.
1.2 is about the best you can get in the real world due to the nature of electromagnetic waves, if your getting SWR readings below 1.2 then your meter is showing false readings. Standard is if you can get a 1,5 on center channel its good but if you can get it lower your even better but there is no real noticeable difference from 1.5 to 1.2 on the other end when they hear you radio....
Coax length has nothing to do with SWR.Electrical length of the radiating element (antenna) effects SWR.
I don't recommend the SWR meter that's built into the radio because Not 100% accurate in my and 50% accurate it's better to use a separate swr Test meter
I agree, just use the built in one in a pinch
Also when buying your 18 ft of coax rg8x is much better preferably 95% shielded, and NEVER COIL IT LIKE AIR HOSE. ALWAYS FIGURE 8/BUTTERFLY. IF ITS IN ROUND LOOP IT BECOME INDUCTOR COIL.
A large loop of about 12 - 18 inches would be ok. Small loops of 6 - 8, no.
Your right thats not a mud tire just a muddy tire
Do you put it back on srf after tuning or leave it at swr?
SRF
Thnx bro
I'm looking into getting a cobra 29 LX. is that to much radio for my jeep?
Mario Martinez that's good model and strong for offroading. I had one forever, I just recently ugraded, but they are worth it, the take good abuse in bouncy vehicles and can sit in hot cars all day and still work just fine when needed
saltyventures awesome thanks for the advice. I ended up buying it and you are write, I was able to hear EVERYONE loud and clear. I put it on my 02 jeep grand cherokee and made a custom box for it along with my light bar switches. came out pretty cool. you can check it out on instagram WJ4x4offroad. thank you
A problem with the LX models is that you can have the antenna system tuned right but the warning light will still come on. I have had to take the cover off of the radio and adjust the pot, L6 I think, in order to correct the Irritation.
nope, it won't alway screw up your radio...I have a Cobra 25LTD Classic, and I've seen videos, and know from experience....didn't effect the radio when I didn't have the antenna...just couldn't send/receive anything
Why are you using ch19? That's the trucker's channel.
i use it to just listen if there is crash police etc and to tell it forward.
There are no rules against listening to channel 19
Roadghost88: Channels don't "belong" to anybody......you can use whichever you want to.
Radio performance will double or triple with antenna mounted in center of roof.
Do what is best for you and your situation. Yea you can put it on top. But if you park your rig in a garage with low clearance that antenna will not last long.
Yeah in the center of the roof with a whip, Trees will tear it off,LOL
Or put some smaller wheels on your truck ,
@@wallychambe1587 simple solution is don't smash your vehicle into trees.
When I key the mic it red lines ..even after I calibrate it?
What cb radio would you recommend for about $50?
Two soup cans and some string.
You won't find an entire setup for $50, unless used, but I've heard the Cobra 75WXST is a nice light use radio for about $70. A decent antenna setup will run you atleast another $25 or $30.
Scott Shuey Now THAT'S funny!
cobra 25 or 18
UNIDEN 510XL is a great little LOUD CB radio.You can also buy a good Used Cobra 29 LTD for that price on Craigslist across America.
On my pickup I have a 102 whip and a Texas ranger with an eight pill box kick on it lol
Eight pills? Was your radio sick or did it have a headache? I bet it has transistors since we get pills at the doctors office & the pharmacy. LOL
Keep your day job
I like that PT Bennie lol
I cant find any radio stores around. Whats going on
Try a truck stop out by the interstate.
It is a dying industry as far as CB shops go.
Phil Shnieder: Look online.....plenty of CB radios for sale.
Thank you.
THANK YOU .. I AM A DISABLE VET.. THIS REALLY HELPED ME BEEN THOUGH ALOT.. I WENT TO THE CB SHOP UP NORTH OF ME 60 DOLLARS TO DO THIS... THANK YOU FOR THIS... GOD BLESS YOU ALL. CB'S WILL NEVER DIE ... SO HOW DO YOU SUPER CHARGE IT TO TALK LONG DIST. SMILES...

A 102" antenna is designed for use with a 4" spring, making it 106" total length. If it is properly grounded, it will not need any further tuning. The needle on your SWR meter will barely move or not move at all. It is the shorter loaded whips that require more complicated tuning, and some of them cannot be tuned to an SWR of less than 1.5-1. That is simply because they are not very efficient compared to a full 102" quarter wave whip. On the loaded whips, if you get the same SWR on both channel 1 and channel 40, and a little lower on channel 20, you've got it tuned as good as it will ever get. SWR will have to be over 2.0-1 to damage your radio, but it will not work very well in that range, you are wasting most of your signal. Many higher end CBs cannot be damaged by a high SWR, they automatically lower the output power to a safe level if the SWR is too high.
A 2.1 SWR will NOT damage any radio.On most every SWR Meter ever built they put a RED area on them because an SWR in that area will cause damage to some transmitters.More than likely nobody will ever notice the difference in your signal from a 1.1.1 & a 2.1 SWR.Do some research & don't take my word for it & look again at that RED section on an SWR Meter & ask yourself WHY if a 2.1 SWR will damage a radio why is that area also not RED in color.RED is a DANGER sign & there is NONE anywhere near the 2.1 mark so PLEASE tell us all why that is if you have an answer that makes any sense.
While an SWR or 2.0-1 may not immediately damage your radio, it will make the finals run hot, and probably shorten their life. But a 2.0-1 SWR means a lot of the signal generated by your radio is being reflected back, and is not actually being transmitted. Since you only have 4 watts to begin with, and waste half that, you're not putting out much of a signal. And if you are running an amplifier, even a low power one, I can guarantee that an SWR reading that high will certainly damage it.
Wow, that was way easier than I’ve been doing for years. Thanks for simplifying this.
I hardly don't want to say anything after you've put so much effort into providing a quality video that in some parts is accurate. I also don't want to steal your thunder.
The main thing I'd like to add is how to properly attach the antenna connector.
As an extra class amateur radio operator with more than 40 years experience that started as a CB radio in 1972 I'd like to suggest that you're putting overemphasis on going out in the middle of a field with absolutely nothing around but weeds to tune your antenna. It's not a bad idea but it's not practical unless you plan ahead.
A 102 inch whip antenna is designed to work with a 4-inch coil. Those are not tuning lugs but rather a simple washer and a lock nut. Putting one in to increase the length of the antenna will offer only a marginal change if any. Taking one out would mean that you would have a lock nut with nothing to press down on. It's already the ideal length. What you have affecting your SWR is more than likely the following.
Ideally, the length for your coaxial cable is 1/2 wavelength. For CB radio that would be 18 feet. Cutting it shorter will have an effect on your antenna tuning. You are correct that you should not generally coil it up but if you coil it up into a large coil you're going to be okay. On the other hand, if you coil it up into a 6in or 8in round loop you have created what is called a BALUN which is a device that converts a balanced feed point to an unbalanced feed point. If you have extra cable you can cut it off or not. In your case it worked out. Look at it this way. Nearly every CB radio antenna comes with an 18-foot piece of cable.
A bigger concern is to route the cable away from certain wiring in your vehicle and in this case in your truck. If it is an old beater 4WD it's probably not going to be a problem. But newer trucks with computers in them are sending computer signals through cables that if you run your coaxial cable next to them they can and often do pick-up noise that affects the range that you can receive.
All in all, a good video. Just a couple of minor points like the washers between the whip and the coil. One thing to consider is that when mounting your whip it's best that you not mount it too low on your toolbox. Ideally you would want to mount it in the center of your roof but when you're out playing in the mud and the trees lower is better. Damn things grab every tree as you drive by it seems. LOL. An alternative to 102 inch whip is a K40 antenna drilled right through the roof. No mag mounts! Commit and do it right.
The last point I will make is weather proofing your antenna connection. First, you obviously want to tighten the antenna connector down hand tight and then slightly more using a pair of pliers. Not too much because you don't want to crimp the connector. They're generally not very good to begin with. A real serious radio operator would cut that connector off and solder a real one on. You'd be surprised the difference that would make in range.
Nonetheless, if you would like to weather seal it correctly you should take some thick epoxy/adhesive 3:1 shrink tubing and put it over the connector in two places. If you are cutting the cheap crimp connector off you want to do the next in two steps.
First, before you solder a high-quality gold-plated connector on you want to slip about a half inch diameter piece of adhesive shrink tube over the cable. Maybe 3/8 in. It's been a while since I've done one. You then want to take a larger about a 5/8 inch adhesive piece of shrink tube and slide it over. Both should be about 3in long or better.
Next, you want to solder a high-quality pl-259 connector. I prefer those that are gold plated. Tips on soldering a pl259 connector on are available all over the Internet and TH-cam. It's actually pretty simple. Using a multimeter make sure that you have not shorted out the connector. Attach the connector to the antenna.
Once this is done start first with the smaller shrink tube. You want to get it up so that just fits over the the cable and just around the bottom of the shredded ring. It needs to be loose enough so that when you apply heat to it it actually has room to shrink. Second, once the first piece cools down take the larger piece and push it all the way up to the top And then shrink it down also. This will give you an absolutely weather sealed antenna connection that will survive the harshest elements. This is how we seal hard line connections on repeater sites high up in the mountains where they receive the harshest weather including snow and high winds. Your connector is also not likely to you accidentally come off.
If you don't want to do it this way and the right way the first time consider the following.
Take a roll of electricians friction tape and wrap it tightly from the top to the bottom and then back to the top again. Once you have done this and cut off the excess you then want to take good quality UV resistant rubber tape and again start at the top but go in the opposite direction and wrap it tightly by pulling on it slightly to stretch it until you get to the bottom and then go back up to the top again. When it settles it will tighten itself up. I like to take myself a black UV resistant wire tie and put one at the top where the tape ends and a smaller one down at the bottom. This will weather seal your antenna so when you're out in the mud or jumping over rocks and hills your antenna connector won't get wet or come off.
I seriously hope you don't mind me going into this detail to add to your otherwise excellent video. Just as checking/matching the antenna for the best SWR is important, so is weather sealing the connector.
Dam dude... why not just make your own TH-cam video and show us how it's done 👍👍👍👍👍👍 seem like you know a lot on how to install hookup and adjust ... and I'd like to see a complete how to 🙂🙂🙂
@@theblacksunshineproject3597 :: because bleepinjeep already did that and I simply added to what he already did a good job at doing.

Rather than steal the Thunder entirely of somebody that spent so much time putting together a video I simply have the opportunity to drop in information that will help with his fine work. I sure have no intention of taking away from him. I'm not here to steal anyone's thunder.
I'm just saying... with all that knowledge... you could make some videos spreading your knowledge
@@theblacksunshineproject3597 :: yes, I suppose I could. Part of the issue is I don't have time. I'm trying to keep moving forward but my grandson has cancer and since my daughter's boyfriend bailed it's just her and I spent a lot of time caring for him. She's trying to finish your college degree so I spend the time during the day with him and I just don't know where I would find the time. I know they're quite a few hands and already do videos and you know I just don't have time. It'd be kind of cool getting some products and do to test them out you know and build up a nice Channel and get some ad Revenue going based on that but I don't know we'll see what happens in the future. Putting on a connector is one of the basics of radio whether it's CB radio or amateur radio. I've got still photos of me building a custom radio antenna that actually works add you only need a handheld drill couple of screws and some copper pipe. I'll tell you, there's some really quick and dirty handmade antennas that you can put on your Jeep for other SUV little outperform a lot of the crap that's out there on the market. Simple is better though. Just using 102 inch whip with a ball mount is really the way to go. I have had projects though where the person had a vinyl hardtop and they wanted a mountain antenna in the middle of that but that wouldn't give a ground plane. So we pop rivet it in a sheet of aluminum inside of it and as we did it we put silicone rubber in the holes so with a pop rivet went through with the kind of went through the silicone and sealed it. Never leaked. Outstanding performance with a K40! Thanks for the inspiration. Maybe I'll actually get around to doing that.
@@theblacksunshineproject3597 :: here is a popular item that if you assist a lot of CB radio operators in dialing their antennas in you can simply use this to check for the lowest SWR and it has a graphical display that will show you the curve of the antenna. That means if your home channel is 20 for example your lowest SWR should be on Channel 20 and from there it should gently rise equally up to the left and up to the right. If you cut quite a little off it'll show it to you graphically. Part-timers don't usually buy one of these though. They're not exactly cheap. But they are accurate. You could charge people $50 ahead or even $25 or through friends to come on over and dial their antennas in. In amateur radio we don't much charge one another to help one another out. It's kind of an unwritten rule that you do it for fun and for free.

I have used CB radios since the mid 70`s ..Well done .. Daddy was a Trucker and we lived on a mountain in Utah and had a base and one in his Scout that we wheeled in...
I just bought my setup and have been doing my research on how to fine tune the antenna. This was a great, easy to understand video explaining the process. Thanks for taking the time to share this!
I just increase or decrease tire pressure, to set my SWR(s). Fuck all that adding or removing washers shit!! Not to mention ALL that added curb weight, it just eats up horsepower!! Other than the spacer-gate folly, not a bad video......
charleskro1 nice lol that's funny
Very good swr reading. Great video mate. Worth watching and using the tips and info. Thanks
