I would like to mount a Glen Martin roof-top tower http://www.glenmartin.com/catalog/page14.html on a Hardishake roof. (Hardishake is no longer made but it is a lightweight flat shake that sort of re
I'm considering a US Towers MA-550 tubular crank up. Plan to put a Steppir 3 el on top. Problem is, I don't have room in the back yard to lean over the tower with the antenna on top. So, question is,
I don't know if this is the best place for this question, but I'll give it a shot anyway. I need to mount a guyed mast on top of my roof. The mast will hold a rotator and some VHF/UHF antennas for 2m

I've been following the discussion about guy wires with great interest. The Phillystrand product is also very interesting. Please excuse my ignorance. How does one go about determining which tensile
I feel really dumb asking this, but here goes. Be gentle! I just purchased a Yaesu G-1000DXA. Upon removing from the box, the base unit appears to have two halves - top and bottom. There is a raised
I have some Belden 9405 rotator cable which contains two wires of 16 AWG and 6 wires of 18 AWG. Where should the 16 AWG wires be used - the CW and CCW pins? I'm thinking CW and CCW since those appear
Thanks to all who responded. I failed to mention that my rotator is a Yaesu. So I'm told to use the two heavier wires for the CW and CCW motor connections. Since only 5 wires are required, I could do
I used Champion Radio's WinMARC tool to calculate the recommended masts for my planned VHF/UHF stack. If I enter an extra safe wind speed of 100 mph (my county is 70 mph basic speed), the tool sugges
Blair, Check out the following URL. You could apply the same concepts as described there. I've seen similar information from other websites but this does the best job of showing alternatives. http://
Wow. Thanks Much! Just a few places found in a casual thomasnet search.. Metal Supermarkets in Redwood City Sequoia Brass and Copper in Hayward Tube Service in Milpitas Coast Aluminum and Architectur
Hi Steve, We'll you're definitely the guy to know. To answer your question, the total wind load calculated in WinMARC is: Wind Speed Total 70 mph 6,151 in-lb 80 mph 8,197 in-lb 90 mph 10,243 in-lb 10
I sure wish I could get an answer to these questions about WinMARC from Champion Radio. Does anyone know? 2) Also, when the calculated total is 12,290 in-lb, the lightest suggested mast type shown in
says "maximum wind speed expected". In my county, basic wind speed is 70 mph fastest mile, 85 mph 3-second gust. So I figured the max instantaneous is probably higher. So I figured 90 or 100 would b
I have a Yaesu G-1000DXA rotator. I'm looking for input on waterproofing the control cable connection. The manual says to simply slide the boot up against the rotator and, while pressing the boot aga
All, I've heard several folks say that "Stuf" will shrink over time. So, the question is - what's the preferred filler to use on connectors? And, any comments (positive or negative) on Permatex Diele
Question about securing the screw portion of turnbuckles and shackles: Some turnbuckles and shackles have a hex head bolt and nut. Some have no nut and the bolt head is flat with a hole in it. Some h
I'm putting up my first antennas on a rotator and roof-top tower and I could really use some help. Sorry if these questions are simplistic for those of you who have put up at least one mast. But bein
Thanks for the many responses RE my questions about strain relief for vertical coax. Sorry it took me a while to respond. With all the great answers, I've got what I need. Boy I do love this list! 73
Uh, well, all of the answers were posted here to the reflector. The short summary is to tape or tie-wrap to the tower leg - various experiences and cautions with each method. 73, Michael - K5MEF -- A
