On my LM470 the thrust bearing alignment is moderately critical. I align it to the center of the tube at the top of the tower by eyeballing the thrust bearing in, tighten the screws and the rotating
The Hygain Hy-Tower is an antenna, and I would not expect antennas to be rated for additional sq ft wind loading. de Paul, W8AEF -- ZF2TA FO8DX FO0PLA 8Q7AA XZ0A -- __________________________________
for the the How about some amateur advice? I believe pipe is measured by ID. Stay away from pipe. I use a 2"o.d. x 20' mast in my LM470. My T2X rotator is perhaps 4 feet from the top of the tower wit
My tower is overloaded and I know it. That's why I run it down during the monsoon wind season as I have observed an 85mph microburst at this QTH. And my existing antenna array on the tower survived t
Point the yagis straight up with the reflector not touching the ground and make your observations. I did this with my monobanders and there was no change when installed on my 70 foot tower. de Paul,
And easier to change the take off angle for improved propagation. (I have observed as much as 20 dB difference just by switching between a 20m monobander at 75 feet and a C-3 at 40 feet, not always i
I have a remote control Triex LM-470 which work very well and I like very much. Make sure whatever you use has a positive pull down. If for any reason the cables go slack during the lowering process
Only if you think there is any possibility of that chain breaking. de Paul, W8AEF -- ZF2TA FO8DX FO0PLA 8Q7AA XZ0A -- Weather Stations", and lot's more. Call Toll Free, 1-800-333-9041 with any questi
You gotta put it vertical with the reflector off the ground to simulate an airborne environment. I did it with my 4 element 20m monobander on a 41 foot boom. I inserted a 4 foot boom extension in the
I started with 1 1/4" od and stepped down from there on my 40m 4 square. The feed point is 10 feet above the ground with elevated radials and each element is guyed 3 ways at the middle. Lots of room
I use the bottom part of the mast from a commercial high band 2 way radio antenna. Don't know who makes them but the one I used had 4 (ea) 1/2 wave folded dipoles attached to the mast and the mast wa
Wish you had something near Phoenix. If you are looking for a site I have 2 1/2 acres about 30 miles North of downtown Phoenix. de Paul, W8AEF -- ZF2TA ZF2JI FO8DX FO0PLA 8Q7AA XZ0A -- ______________
One of my co-workers at RCA Broadcast claimed to have been part of the group that helped determine the optimum number of radials for a (am broadcast) vertical antenna. He told me they placed their re

I use two Weller soldering guns. 140 watts for the center conductor and 250 watts for the shell. Also, I tin the braid before I cut it with a tubing cutter. Makes assembly and soldering the braid to
I found that 3" thin wall irrigation pipe will slip over 3" PVC which in turn will slip over 3" chain link fence end posts (mine measures 1/4" wall, 2 3/4" od). I plugged the inside of one end of an
Don't know about the WX0B stackmatch but with the Comtek phasing box you use 1/4 wavelength 75 ohm low loss coax for the lines from the box to the elements (I believe these are impedance transformers
I use a modified HyTower on 160m with 4 elevated radials. The first time around I wound a coil and base loaded it but it turns out that at the top of the tower there is a high voltage point between t
I have 4 element W2PV design monobanders stacked on my 72 foot crankup. And I have a Force 12 C3 on a 37 foot tubular crankup. During domestic contests I find the C3 outperforms the monobanders from
