- Easy to build antenna for 2 meters. Follow along as i show you how to build a Quarter wave ground plane for 2 meters. From start to finish i walk you thru
all of the materials and measurements. Let's get started.
Well this might be one of the best videos I've seen. Definitely going to make that.
I have the 1st. on that I made still up at my house. It just works.
I am a new ham and decided to make this antenna after watching your video. I made my first contact as a ham with this DIY antenna!! I had great reports with it, loud, clear, no hiss. Thank you for making/posting this video.

Welcome to the hobby. I'm still using this antenna from the build in the video. It's been up here at the house for many years now. I have also built a few to give away. Glad it's working out for you . Steve - Ad4xt
I used 14ga. Pretty flimsy but i got it down to 1:1. I'll rebuild it tomorrow with 10ga and see how it works. I hit the local repeater with 0 white noise and it sounds better than my mobile antenna on my silverado. I actually tested it on the silverado for a comparison. I propped it up on my tunneau cover.
Your wire straightening technique alone was worth the price of admission. Another great video. Thanks! 73. W0OSH.
Good deal! Thanks for the watch.
06:40...love your ingenious 'press/roller'.
I built one of those for the UHF band. It’s so tiny it’s actually cute. Thanks for the video. I enjoyed it.
I have been binge-watching a ton of videos on how to make antennas, and this is by far the best. Very clear, well-paced, all the parts & steps are shown (!), and you have a relaxed & pleasant way about you. And, this looks perfect for my first build. I have just passed the Technician test & no call sign yet, but am subscribed to your channel & we'll surely meet again. All the best & keep up the great work!
Great little antenna. FYI, I attached the radials with wingnuts to make it easy to disassemble and stow.
Great idea.
Im in process of having fun building one now i have everything except some 8x coaxial ill have to order some thanks for showing how to build it!! 73" KF0LOZ
Thanks! I just built one from this video and my swr on 146.52 was 1.0 from your measurements. No trimming a 1.0! The only difference was I used 14/2 Romex
Thanks Joe !
I made one of these, it worked great!
Thank you for the video.
Hello yes I would like to build an antenna and it looks like you did a very very good job you put that little hook on the drive part of the antenna and I would like to put that antenna on tree just a minute down
The very first one I ever built is still in use. That's 8 years of service for me. Waterproof the connector and coax well.

Great video I'm studying for my technician license taking test next month. And got me A yaesu ft-65 today with a comet antenna. So now I'm going to copy your antenna for house and camping THANK YOU!!!!!!!!!!!!!!!!
Thanks and good luck with the test.
Thanks for showing this I recently had to move and living in a camper I noticed I could only get 1 or 2 repeaters with my hand held and all my stuff is in storage I think I will definitely make one of these KN4FJQ 73s
Excellent video, thank you!
I've been inactive for a while and am getting back into ham radio. I remember building one of these a long time ago but your loops that you add on the ends take this ground plane to a new level. I subscribed to your channel. I'm going to have to binge watch everything to see what else you have. Thank you. KE4VBB
Thanks Rusty, good luck.
Hi Steve!
My son (6th grade) and I are new to radio and we built your antenna this week.. it works great!!! Your description of how to make it is very good and easy to follow. Thank you so much for the video... and the hints (like the loop at the top of the vertical--really easy to hang it!) -m KF0CPK
That's great to hear. I built several of these at our clubs Field Day for the educational points. I gave them all away to the new techs. Thanks for watching. Steve Ad4xt
How/what are you doing on the radio now three years later?
Awesome
Just got my Technician License. Total novice. This is excellent.
3 years later how is your radio practice going? Did you ever upgrade your license? What have you done?

Greetings
Thanks for checking up!
I did upgrade to General.
I haven't done any building but do a little chatting.
Mostly check in on the weekly local net.
@@atticusfinch4687 great! That is about what I have done. I did a fox hunt, got very close but ran out of time. I built some antennas, they worked great.

I just builded it, and it works on 2 Mts and 70 ctms! Thanks You!
That's great! Be sure to check your reflected power if you run over 5W on 70cm.
Steve, I just stumbled across your channel and wanted to say thanks for the geat work you're doing.
Also, I have a tip: when trying to straighten out a piece of wire, slide it into the chuck of a drill. You may have to attach a small piece of string on the opposite end with a counter-weight if it's a longer wire. When you spin up the drill the opposing centrifugal / centripetal forces will straighten a piece of wire like new!
Hey Brian thanks for the add. I'll have to remember your tip about the drill next time.

Great video. Thanks for sharing.
Great antenna
Muito bom...73..de pu2 OFJ , Luis/ Brasil...
Man thanks for the video I was getting ready to build one just like that with the loop in the end. But didn't know if it would work or not but I wanted to make it so I could hang it from a tree. Boy you answered that question
Does it have to be copper wire I have several roles of electrical fence wire do you think that would work also. Thanks
That electric fence wire is tricky. Use any solid copper wire you can find. Steve - Ad4xt
@@hamradioportable1630 thanks
Would this metal hanger wire work? (Shiny smooth galvanized steel wire coat hangers are rust free, waterproof and will not decay.) Thank you for the great video and important information for a newbie like me.
Sure give it a try.
Great video. Quick question what kind or size coax wire are you using. Thanks
Rg8x for testing.
@@hamradioportable1630 is the RG8X the same size coax for using on normal use with a portable handheld radio also Thanks
ty for your time and effort showing us how to make those antennas. question can you please show us how to make a packtenna. 7 3
Packtenna what is a lightweight brand of commercial products. Well made, a bit pricey. I do have a lightweight linked dipole, maybe I'll fo over that. Thanks for watching.
Very neat...thankyou.
Awesome. 9W8ABM abu bakar Malaysia
Very nice job on the antenna! I am getting back into radio after many years of silence, so I have a somewhat silly question. What type of coax cable (ohm) did you use to connect the antenna to the rig?
Awesome! Thank you!
Great tutorial. :D 73s
After some shortening swr is flat on 2m and 1.5 on 440.
Good vid!
Thabks for doing these videos. What kind of coax do you carry around for running up a tree?
excelente...73" LU9DRC
Yes. I built that one, now i m thinking to make this 1/4 lamda groundplane antenna with coil phase inverting..
Is that possible?
Sorry about my poor english 🙏
Question? Willl adding a lighting arrestor change the characteristics of the antenna ?
It should not have any effect as long as you have it on a ground rod before it enters your shack.
What coax did you use?
RG8X , not ideal but good enough to hit local repeaters in my area.
What is the make and model of your radio...also, what power source are you powering your radio with. Thank you in advance.
I use a Yaesu FT-2900r . Its replaced by the 2980r. Mfj-4230mv switching power supply. Both have been solid.
Thanks for watching.
Also have the Yaesu 2980, can you use this antenna with 80 watts for simplex? Great video, 73s.
I own a Yupiteru mvt 7100 handheld scanner. Is it possible to build a 1/4 wave antenna for it. Anyone ?

How much further can you talk at that tree height
Height is might as the saying goes for VHF. High as you can.
On more thing you would laugh at my Ground plane antenna but it works for me🤣
Great! , I'm glad it's working out for you.
PMR 446 mhz
Vertical monopole 16.13 cm
4 Radials. 18 cm
LPD 433 mhz
Vertical monopole 16.61 cm
4 Radials. 18.61 cm
144 mhz
Vertical monopole 50 cm
4 Radials. 56 cm
Diameter 2mm
the inclination (degrees) of the 4 radials +/- SWR
Will it matter if I leave insulation on vertical wire?
Not really an issue. Keep the insulation.
Top,para mim é a melhor antena que existe,sem dúvida ,parabéns,pu2.o.f.j 73...
Can that be used for GMRS
Yes , if cut for the proper frequency.
Thanks
Good afternoon
Send me the dimmensions in cm.
I don't have them written down. Just stop the video at the point of the dimensions and copy. Always cut a tad long to have room for trimming.
Gain?
Not as much as a commercial 5/8 wave antenna. It has worked so well for me. I use it for the educational part of Field Day every year and give them away to new hams. Most are still using them. Our furthest club repeater is about 22 miles away. No issues.
