[TowerTalk] GM 9ft Roof Tower is up

Mon Jun 11 13:39:55 EDT 2007

Has anyone here on the TT list actually used one of the 26' tall Glen Martin RT-2632 roof towers? If so, did you need any guying, or did you use just the recommended bolts into a solid wooden base in the roof?

I had a new garage/shop building built last year, and I gave a copy of the GM 26' roof tower prints of the required base and support wooden beams to the garage construction crew (which are available on the GM site). This was so that they could incorporate sufficient sturdy wooden beam supports in the roof while they were building the garage, as were recommended for the RT-2632 by the Glen Martin Co. All of the recommended heavy wooden beams are under the shingles, placed where GM recommended, and securely anchored to the rest of the roof support trusses. I figured it would be best to do this while the garage was being built, instead of as an afterthought. 

It looks like a challenging project to have something this big mounted on a roof. I originally considering having one of these 26' roof towers installed on this new garage to support something like a TA-33 3-element tribander beam or a 2-element triband cubical quad antenna. I'd be interested to hear about anyone who used one of these roof towers, or even the next size lower version.

>Thanks for all the suggestions, pictures and help.  A4S looks very sturdy and stable up there.  Tower was dead level when we were done and mast is level vertical.   My brother who is about 210# stood on the tower to do a couple tweeks and he said it felt firm and not shakey.  We used 8ft 2X8s on the rafter side and the bolts go through pressure treated 2X4s on the roof then into the roof and into the 2x8s.   Sealed it all with roof tar sealer and it comes through the bolt holes. also sealed around the 2X4s and on top of the tower feet.
