I have a chance to get this tower from the nephew of a Silent Key. I am Trying to ID it so I can hunt down more info on it. I was put up in the late 70/ early 80. Anyone have a guess.

Looks like the Rohn BX I have laying on it's side in my back yard. The smaller pieces stack nicely in the larger ones. If it wasn't dark I'd take a pic to compare.

I counted 7 sections. I thought all sections were 8 foot long. but looks like first 2 base sections are 6 foot using the house as a height judge.

Becareful with this tower. It is a nice tower for small antennas. Designed to be free standing, adding guys will not help the strength.

There is a maximum boom length for a reason on this tower. Tower is designed to twist to absorb the load. Too long of a boom with some wind and it will corkscrew itself to the ground.

3 or 4 element tri-bander, 6 meter 5 element, 13 element 2m, VHF/UHF vertical  would be max but not all at once on tower. Remember to check surface are and weight specs.



Lesson lived and learned cost me a nice TH6DX tri-bander back in my early years as a ham.  But traded what was left of tower for a NIB Mosley 80-10 vertical.

Thanks Guys!! I feel a lot better knowing what I am dealing with. I can still get parts for it! Now just have to rent the boom to take it down with.

Doesn't look like something I'd like to climb.

I really need to find a tower to climb. It's been a couple of months and I miss it.

Do not take that tower down in one piece use a GinPole and a jack. That tower is not as rigid as standard tower and you will probably fold it up laying it down in one piece.

I plan on renting a boom like this and take it down section by section.

That's the easy way to do it.

The ginpole rocks. I still need to get mine back from the last job I did. It's still at the top of the tower. I really need to build a jack platform. Nothing like using a 2.5 ton floor jack 70' in the air.

I am a fat man - I like easy

Plane is to drop it down, repaint it, get the antenna setup ready then put it back up. Hope to have it done in a month or two.

Actually you should be able to get the top three sections down by yourself with hand tools and a rope.

Again the fat man part come into play- I don't want to trust the cross members to hold 320 lbs

Also because of the cross bracing there is not flat footing on the tower. Your feet are always resting at an angle, they slide down brace and end up pinching your foot.

Rent a bucket lift that will go about 60'.  Then you can lay it down safely in 1 piece... just use the bucket like a crain.

A bucket lift can be very handy at times.. lol
