The thing to remember is that relays are rated for hot switching. In ham radio use, that should "never" happen. Thus the relays are actually good for quite a bit more power. Rick N6RK _______________
On the other hand, TopTen has used very inexpensive DPDT relays in its 1500-watt remote relay switchboxes for a decade or more. They are Panasonic brand JW1FSN-DC12V (12V coil), priced at 2-05 in one
Bear in mind also that you've calculated for the proverbial (and non-existent) "well matched system". The typical rule of thumb is to require design to 10dB over or test to 6dB over the expected maxi

Hi Mark Not sure if that is like the rotor I used to have, but on the one I had, there was a lever on the bottom of the control box that set the end stop for the rotor. You could swing the rotor all
Greetings, I recently was given an old CDE rotor, I'm thinking it's an AR-40, as it has the familiar bell housing for the motor, but the lay flat on the table control with the old fashioned clicketyc
Yes... I figured that... but I kinda liked the term, anyway. Sounds sort of dressy. And, besides, a top hat has a flat top. So, maybe not so far off, eh? ;-) Thanks for the clarification, but I figur
--Original Message-- Well, there is that... Even if the pipe is 3/4" wall, the bending loads are huge in this sort of thing, you need to calculate some stuff to see if it's going to work. 4" is prett
David, I would venture to say there are more insulated, serial fed towers in the air, than grounded through the foundation amateur towers, by a fair margin. But I could be wrong, and it's totally aca
Per your comments, the two towers you refer to were isolated from the concrete base. That is the same condition described by Polyphaser for the single semi-verified claim of an exploding base they co
I can show you pics of what it will do to a foundation on our towers first hand. It isn't pretty. 73 Dave n4zkf Southeastern Territory Supervisor American Tower Corporation David, Urban legends? I do
David, Urban legends? I don't think so. WCTC-AM, New Brunswick, NJ. Took multiple strikes, and had structural cracks in the foundation afterward. This was in the 1965's, when I worked there as an eng

You may be right, sad to say. The price of the gear might become (more) stratospheric, then the bean counters will want the ham product line dropped "due to poor consumer demand". I hope not, but I d
