I live between Cincinnati and Dayton, OH. Last year I had some Rohn 25, Rohn 45 sections and misc other tower parts regalvanized. I currently have another batch of stuff, including 70 feet of Rohn
I have a t588 crankup,I am going to need a base for a new install.I tried tashjian towers and they no longer have info,I will try texas towers next,If anyone has the manual and could mail or scan and
Need to better understand the 75 ohm half wave coax balun on the T-Match of a yagi. I have a number of M2 V/UHF antennas, from 50 MHz to 432 MHz, that use RG-6 for the balun. Since RG-6 has a tiny fr
The DIN connector was for an external preset control that to my knowledge never made it into production. The control box has a switch on the front that is labeled 'Manual' and 'Preset'. I still have
Several years ago someone on the VHF email list swept a connector of this style and didn't find any problems until 1296. And then there was a slight impedance bump on 1296. FWIW I have been using thi
All the following is IMO: Andros connectors are the ones that taught me to be very careful about the center conductor length. They were the 3rd brand (I think) I used of this style of connector. Befo
I used Davis a lot in the past. But their LMR-600 price doesn't even come close to TexasTowers. Don't know about shipping a 1000 foot reel though. 73, Jay K0GU _______________________________________
I have a 1000 foot spool of E76191 CL2P RG-58/U that is at least 15 years old. I'm not having much luck finding any specs online. By any chance does anyone have the specs for this cable? Mainly inter
I just measured one of the two TB-4s I have stored on the basement. Less than 3.1" diameter opening. 73, Jay K0GU _______________________________________________ _____________________________________
I though that some time ago it was decided that the torque bars weren't really long enough to give any advantage? Does anyone have the real scoop from way back when?? I recently extended a Rohn 45 to
It's not too difficult. Just make sure you don't get wires caught in the wrong place when you reassemble. These are terrible scans but they might be somewhat helpful. http://i509.photobucket.com/albu
Just curious why? I have two OR-2300s (one is 20 years old) and two OR-2800s (newest is 11 years old) and I've never had a problem with the limit switches. I've been inside all of them to change pots
I also use a come-along. I put a U-Bolt on the mast, tie a rope to the U-Bolt and run the rope though a snatch block mounted on the top rung of the tower. Then attach the rope to the come-along outsi

I have a G-1000SDX with a 300 foot run of #18. Used #18 because I already had the wire. With a heavy mast (21' x 2" OD x .250" wall steel) and not a lot of antenna wind load (5 sq feet) it works fine
Your best bet if possible is to model the antennas and look at the gain compared to one antenna and the patterns. The wider the horizontal spacing the bigger your first side lobes. That may not be a
The azimuth pattern will be much the same over ground. If you vertically stack antennas very close together you can see interaction between the antennas that can degrade the azimuth pattern. Although
Just take into account that VE7BQH's fine antenna array information is a maximum gain design for EME. The first side lobes in the azimuth are only down around 12 db from the main lobe in many of thos
You won't get any argument from me. Wave angle diversity is always a good thing. The guy wanted to know about 4x H-Frame (box) array spacing so I provided some data. But not everyone can have a 100 f
