- After 2 months of work, the tower is up and functioning. Everything works great and I couldn't be happier. Any comments are appreciated and please forgive the amateurish video. It's not my strongpoint, but it shows everything I want you to see. Thanks!

Nice Practical tower raising video. Thank you. I have no where to put a tower and I think people like yourself who have invested in the antenna system have a whole different experience than us end fed wire guys do.
Cool video I love that control box.
I love my tower and how it looks with all the antennas on it. I have a 45 foot triangular crank up attached to the back of the house. Im going to do the same thing with the paint next summer..
Thanks, Im entering the ham radio relm and I find this very interesting and it helps me out in my future plans.
That's great. Good luck. Was a lot of work but paid off bigtime!
That sure is some beautiful sculpture in your backyard. I had to laugh when you said I hate how the antennas are just a little out of whack. I understand completely! One hell of a job for doing it by yourself!! Keep up the good work and hope to hear you on the air soon!! W5PN!👍👍👍😎🇨🇱 I have some rohn 45G up at the same height. Force 12 Antenna going on the top soonnnn🥵
Thank you sir!
Excellent. Remarkable work for one man to do. Congratulations on a job well done. I just found this site and subscribed. Merry Christmas to you.
Thank you. Much appreciated. Merry Christmas to you also!
Super great vid. No need to apologize for this vid at all. It's great!!! Thanks and good luck for the next 14 years, too!!!
Thank you sir!
@@hamradioadventures8856 Only the men in blue call me sir...so I put 2 and 2 together and got 4....!! ha! Thank you. Hope to catch you on HF. I can be found on CW around 7.060 Mhz plus or minus the QRM !!
Looks really good 💯👍
Thanks
Nice job !
Hi Mark,
I enjoyed our QSO today on 20meter. This is a Great setup! I can see that you take great pride in your work.The Mosley TA32 is exactly what I hope to achieve. i’m going to contact Mosley and see if they will send me the schematic. Thanks for turning me on to your you tube channel.

Thanks J.R. Only mistake I made is the rotor loop. I'll explain the next time we talk. 73's
Good Job !!!
Thanks!
Wow. I'm 100% jealous. Lol. Great narration and videos of the install. I was wondering how close you could install multiple antennas on the same mast. You have given me so many ideas for my future tower as well. Thanks

Thanks! I consulted with 2 other hams that also work the broadcast industry. In addition, these guys have 5 or 6 towers up with all kinds of ham radio stuff. The rule they told me to use is HF on the bottom, 6 meters next about 3 feet above HF and the 70cm at the top with 3 foot of spacing. So far it is working perfectly.
@@hamradioadventures8856 That's awesome. I feel like the that really simplifies the whole thing. And it will make my wife happier too. Lol. Glad you have good reports from it too. I'll have my inverted V up soon and I'll post videos on my progress too.
Turned out awesome, finished mine and raced it in the air day before yesterday. Much of the same way you did. But using a winch on the front of the truck, I am 72 foot in the air.
Thank you. It worked out for me, but took a long time to prep everything.
wOow..very very nice !! great video !! big pleasure to watch !! Thank you for share this sir !! i wish you a very good dx ,7351's from Patrick !! 😉👍🎛🎚📡⚡️⚡️⚡️
Great video! Thank you for sharing. 73 PA5BAS
I wish we were neighbors I could give you a hand ❤. Nice place btw 👍👍
Nice set up. I have similar, but 60" Rohn 25g andmy mast is 10' steel chainlink fence toprail.
Does the mast hold up well?
A free-standing tower that tall with NO guys! That's a little risky, hope you never get any high winds.... Never could do that here where I am... Good video!!!....................73's de WB6PVC
Manufacturer did not require guys if you stayed within specs.
you have the same rotator as I do and same thrust bearing. Good job. my tower is a no name tower at 72 feet tall. Not sure who made it cant find any markings on it.
neat idea for the coax clips Mark, shame you didnt use them, on my tower i use 4 inch diameter undeground drainage pipe zip clipped to the tower @ random spots to feed my coax and rotator cable through (i have a box section solid tower), one last observation though Mark ,why not run coax below the rotator inside of the rohn ?? the cables could have been zip tied together and left to be free inside the tower structure as they could not move to the outside ??
Since I did the whole thing alone, I just decided to tape, and zip tie the coax. Was getting worn out. LOL. Also, I would have had to clamp the coax blocks to the tower. I felt it was one more thing to rust or loosen. I thought of running the coax on the inside of the tower but opted for the outside in case I need to replace a cable. Makes it simpler for me. Thank you for taking the time to comment. Appreciate it.
Did you add any anti-seize compound on your tower bolts? That could be a good add-on the next time the tower comes down. I also run a 2-element Mosley, which was an excellent choice. LMR-400 cabling?
Yes it's all LMR-400. Never had a problem with the tower bolts seizing. The Mosley yagi(s) are fantastic. I love them.
Quick question what's the total weight of the three antenna?
What was the length of the aluminium pole that you used to mount antenna?
The HF Mosley TA-32M is 26 lbs., the 2and6 is 21 lbs. and the 70cm 14 element is 12 lbs. Total 54 lbs. plus LMR-400. The pipe is explained in one of my videos. It is a schedule 40 aluminum 20 feet long with 9 feet above the top of the tower. For strength, I inserted a smaller schedule 40 pipe from the top to just past the thrust bearing. Then I placed one stainless bolt at the top and one at the bottom to keep it in place.
Nice tower, how high is the tower & what coax did you use ?.
To the top plate is 64 feet. I used LMR400 on everything.
Thanks @@hamradioadventures8856 look forward to more of your videos
I have access to one of these towers but I would like to do it like you did here. Someone told me it wouldn’t hold the wind load of a 80lb triband yagi. Do you think that would be pushing it ? From emails to top dxers , I’ve heard them speak of 2” dom tubing dipped in galvanize for a mast pipe. It flexes just enough so it won’t break under flexing in a high wind situation like gas pipe or alum will. I can’t confirm that. I just don’t want to go through this and not be able to install a momo tri 10 or Jk tribander. I haven’t liked my ta33 but that may be due to current height above ground. 15m is not much on the Mosley.
The change to LE was easy for me. I still have friends from the CBS days. I am actually retiring in June after 31 years. As far as the antenna wind load; I can only tell you what I did. I checked the wind load and sq./Ft recommendations as listed by the manufacturer. My tower is about at its recommended limit. I have had no problems up to 75 MPH winds (the highest so far this year). But as I said in one of my videos, because there was an underground water flow when I started to pour concrete, I ended up with 11 yards! The concrete info is in my Ham Radio Adventures 1. So the tower is super anchored. What I did for the mast was use Schedule 40 aluminum pipe. I inserted a smaller piece of pipe inside the first pipe so I had more strength in high wind. I also show that in another one of my videos. I am currently looking for another tower in addition to this one. Good luck and thank you!
@@hamradioadventures8856 congratulations on retirement to be. Hope you bring us along with more projects. I watched your earlier videos after this one so I learned abit. Nice qth location there. Can shoot when you want and dx when you want. Good deal
You must have serious losses in that long length of coax, wonder why no masthead pre amps for vhf/uhf?
If I do it's not taking a toll. My signal strength is always reported fantastic on 70cm, 6 and 2 meters. All LMR-400 low loss.
Hi there! 73. What model are these antennas? Tnx. 73.
HF Mosley TA-32M, 70cm is Mosley MY420 and the 2 and 6 meter is Mosley 2and6 model.
@@hamradioadventures8856 Many many thanks.! 73 de IZ2OAV (WB5ALF)
How do you figure the load on the raising cable?
I posted the answer to that. I'll have to look and see which video it is.
@@hamradioadventures8856 okay, let me know, I appreciate it.
@@roynorman3650 try this link for the formula and let me know if it does not work. photos.app.goo.gl/Beaqss85yL1QoA5z6
@@hamradioadventures8856 I've seen this formula as well. I've heard different ideas about this, and just want to be sure. It seems like it would make sense. I appreciate it. I use to think it was only dealing with the tower weight.
@@roynorman3650 Using this formula, and based on previous experience with towing known weight, I think it was pretty accurate. At least to get the right gauge cables for the pull. The next time I lower and raise the tower, a friend is loaning me his weight gauge that you put in line with the cable. That will be an accurate way of verifying it. I'll post when I do that video, but it'll be later in the spring. Recuperating from knee replacement now. Thanks for the interest!
"N" as in Nora? 🙄
Rust use navel jell. Used on ships for years
Great job!...I have the same tower but its a 40 foot version. I haven't put it up yet but need to. I have the rotor, control box, coax and a A4S. Need to get this done.
Can I run some coax to your place ......JEALOUS!!!!! de VK2AOE
As long as it's LMR-400 sure! LOL
