I have acquired a few sections of Telrex T20 tower and am looking for accessories, particularly a rotor plate and thrust-bearing plate. Anyone have ideas about sources for these items? Thanks, Jack,
It does seem to be the old Tri-Ex tower, but not T20. I visited the Tashjian Towers web site and looked at specs for the various towers...the T15 tower looks like an exact match. Unfortunately they m
I just looked at the KT-36XA documentation and it does give instructions for installation of the "overhead guy support", as M-Squared calls it. Looks the same as my old KT-34XA. Jack, W6NF __________
Even properly attached to the fascia you must be careful. I recently made an inquiry about my Tri-Ex T-15, which is slightly larger than Rohn 25, and was told that bracketed at about 13 feet the desi
I've been using the 4-foot aluminum cammo support tubes (1-3/4 inch OD and fairly thick wall) for some years now and they work fine for 1/4-wave 40-meter verticals. I have mine guyed only at the 32-f
I have a flat-roof base for Rohn 25 that I want to sell...anyone have an idea of what it might be worth? I have no idea what might be a fair price. Jack, W6NF Silver Springs, NV _____________________
Hmmmm...My experience is quite the opposite. I acquired an old KT-34XA 18 months ago and had numerous questions for M-Squared. All were answered quickly and thoroughly *and* I was able to purchase in
Thanks to all who replied. I found that the mount is a Rohn FR25G and *very* expensive (by my standards) at an MSRP of $339.00! 73, Jack, W6NF _______________________________________________ ________
Don't forget the possibility that it could be Tri-Ex T-15. I have four sections of it, along with Rohn 25, and at first glance they look identical. The center-to-center spacing of the legs is slightl
Hi, Bob: I use black Dacron line (mostly 3/16 to 1/4-inch sizes) for supporting my verticals and inverted-L's, up to 48-feet with my top-loaded 80-meter vertical, and have had good results. Some of t
I want to put up a 65-foot base insulated vertical, likely using Telex T-15 tower (similar to Rohn 25 but a bit larger). I have a copy of W0UN's note about utilizing G-10 rod as insulators but would
That's an interetsing suggestion, Jim, but since I have no experience with such material I will probably avoid anything that requires engineering. I do have a large quantity of rod material that was
I appreciate the numbers, Jim. We threw away a McMaster-Carr catalog yesterday here at work (I guess we got a new one)...should'a taken it home! BTW...I don't know why I have so much trouble with thi
I have a Rohn 25 flat-roof mount that I will likely never use. Asking $100.00 plus shipping. Local pickup (Reno/Fallon, NV area) might be arranged. I iwll be that the DX Convention in Visalia on Apri
Worse than just a shame, Terry, a travesty! Whoever controls the content of LB's web site needs to explain, fully and quickly, exactly what will become of the site. and the contents. 73, Jack, W6NF _
Even though LB provided the material on his site freely to everyone and was always most helpful and courteous when I had a question to pose? A fine way to pay homage to his memory. Hopefully this wil
Hi, Roger: I've never built one but we have quite a few 30-foot crankup masts at work that are made from thick-wall square aluminum material. The lower part of the mast is probably 6-inch outside dim
You might look at the "BV6" long yagi by DJ9BV...2.1 wavelengths and 10 elements. Jack, W6NF _______________________________________________ _______________________________________________ TowerTalk
One of the horizontal loops would be a good choice. When 6 is open you can work 'em with a wet noodle so the loops should do a nice job. 73, Jack, W6NF Silver Springs, NV DM09ji _____________________
Just like the antenna systems used at FM broadcast stations...figure roughly 2.5 db gain every time you double the size of the array. If you start with 2db gain (maybe a smidge low) then 4 loops woul
