Does anybody know where/how I can buy a Daiwa switch, model CS-4? It's a single pole, 4 throw, rotary switch with BNC connectors. I use it to switch my Beverage antennas and I need four more of them.
Norm, I found Universal Radio, but they don't have the CS-4, only the CS-201 and CS-401. Anyone else have any ideas? Bill List Sponsor: ChampionRadio.com - Trylon self-supporting towers, safety equip
Fred, There are several documents on "camouflage" available from Global Engineering Documents, which is the commercial sales arm for military/industry manuals. Their URL is linked from my Website, ww
The 1022B is the "small" RR. I've never heard of a full-size 40M 3L mounted on anything but a 1032 "large" RR. That large antenna, with all of its wind area on three moments flailing around in the wi
I upgraded both of my 40-2CDs to (++) per the W6QHS articles, which may be found at: http://www.qsl.net/w6old/402cd.html In addition to the QHS++ modifications, I added a *thin* galvanized steel inse
I couldn't agree more. Use aluminum for antennas. Use steel for structural members like masts, towers, etc. Bill, N3RR List Sponsor: ChampionRadio.com - Trylon self-supporting towers, safety equipmen
Tom, Think about what you are trying to do from an antenna propagation point of view. As stated, you wish to obtain some kind of directivity-switching by being able to switch from one set of inverted
There's little or no difference between 50 and 70 feet on 80M. Bill, N3RR as though being take-off List Sponsor: ChampionRadio.com - Trylon self-supporting towers, safety equipment, rigging gear, LOO
Also, the greater the distance you place your guys from the tower base, the more stable will be the system and the larger the turning radius may be of any beams you might want to place on the tower b
We're talking about making a switching directive array out of GUY WIRES. That's a lot of work. So, what is the benefit. That's the analysis. A pair of inverted "V"s at right angles will be very simpl
Mike, You asked a few questions. First things first. Here's my step-by-step approach to deciding on what coax to choose: 1. Decide on the loss you can accept in your coax run from TX/AMP to antenna.
Thanks Press. Your excellent comments should be posted to the reflector for others to see, so here they are. Thanks again, Bill, N3RR List Sponsor: ChampionRadio.com - Trylon self-supporting towers,
Before installation, I drill several 1/4 inch holes in the conduit at the low-points of the run to exit the water. List Sponsor: ChampionRadio.com - Trylon self-supporting towers, safety equipment, r
On my Website, http://www.erols.com/n3rr I have included a section on the design of my multi-band tower system. Click on "Guying Subsystem" (http://users.erols.com/n3rr/guying/index.htm) to see a com
Any "warm" coax in the shack is problematic. It's a symptom of some resistance to ground within the feedline system and that's not good. That means some of your power is being dissipated inside the s
If the coax is routinely getting warm due to the transmitted energy being applied to the coax, and the load (antenna) is properly matched, then it's the wrong size coax for the application. If your c
That's fine. It's just my opinion. No problem. But, I didn't say to replace an amp if it gets warm. That's the wrong analogy. Coax doesn't generate heat. An amp does. Bill, N3RR
Jerry, you have opened up Pandora's Box. This subject has been discussed over and over again on the reflector. While I just came back on the reflector yesterday from several years of absence, I recal
There are two mismatches: one at the antenna and one at the transmitter. So the mismatch is a bit more. I'd pop for the $30 - 50 in LDF-4 @ hamfest prices and eliminate these mismatches. Bill, N3RR e
