Towertalkans - I remotely control my G-800dxa rotor via the "ext control" plug on the back. There are pins that make the rotor turn (1 and 2), and pin 4 to read what direction the antenna is pointed.
TowerTalk Folk, As a tower novice, I have been looking into wind load calculations, to see what I can really afford to put on my US Tower TX-455 (rated at 12.3 sq ft of wind load at 70mph). I had bee
Stan, Thanks, the emergence of a new method may explain why Force-12 does things the way they do. The square root of the sum of the squares method also seems to be what ex-W6QHS uses in his "Physical
Hi - I have a 80m dipole to put on my tower and have a US Tower "Inverted Vee" mount that rotates freely on my 2" mast. If I want to put that up a few feet on the mast above the top of the tower, I n
Tower Talkans - I wanted to follow up on this posting from last week or so. Ive interacted with several folks about this including W7NI, N4ZR, K7LXC, K5IU and others. I've gotten some helpful but not
Hi all, How hard would it be to shut feed a 55' crankup tower with 10' mast and C3/D3W for 160m? I could add some top loading wires. I read that the coax to the HF antennas should be run through the
Thanks to all of you who responded to my querry about C3 Rivets - many have successfully used 1/8" hardware store aluminum rivets. Bill, K4CIA was kind enough to find the definitive recommendations f
Hi All -- Does anyone know if the rotator/motor units between the G800DXA and SA rotators are identical? The differences between the two appears to be in the control box - presets, computer control,
What do folks do, if anything, to prevent climbing on US-Tower crankup towers? US-Tower does not offer anti-climb panels as far as I can tell. Im thinking about using 3 15" wide pieces of wood that I
Hi all -- I recently received the formal specifications from US Tower for one of their towers and was surprised to find the wind load at 50mph to be quite a bit higher than what they advertise. Any i
TowerTalkans -- I'm planning my first tower, a US Tower TX-455. My building permit was approved today, so Im about ready to order the beast. Some questions if anyone would like to share the benefit o
Dumb question - what criteria do counties typically use to decide whether or not a building permit is required? I realize that towers usually require permits, but I don't think short, ground mounted
TowerTalk folk -- I'm looking to put up a tower in San Bernardino County, Ca and I'm interested in input as to what sort of permit/engineering help I should seek. I live in Orange County, Ca on a sma
Towertalkans -- I recently built a 40m 4 square from telescoping aluminum - 4 ground mounted verticals, phased with a Comtek box. Each vertical has about 60 radials, a little thin in the interior of
Towertalkans -- This isn't exactly a tower question, but Im looking for suggestions on raising a push-up mast (various circumstances preclude a tower at this time). I have read countless times about
Towertalkans -- Is there any good source of Rohn tower sections and hardware in the general Southern California area? I've heard there is a local supplier but they charge high prices. Is it best to o
Hi all, I have a AB577 mast and I need to put a rotor on it - if someone out there has done this and would like to share your approach with me, please drop me a line. I built an adaptor I am not comp
