I think most have missed the point of the original poster on "antenna size". I believe what he was referring to when he said "a small antenna radiates just as well as a large antenna" was in referenc
Anyone have the specs on the Hygain Rotobrake 400 rotor? Thanks Gary K4FMX _______________________________________________ _______________________________________________ TowerTalk mailing list Tower
What you need is a sliding joint in the mast near the top to take the weight of the mast off the tower. A set of square tubes that telescope inside each other, a couple of feet long, welded into the
What do you mean by "mounting antennas alternately up a mast"? Pointing them at 90 degrees to each other? 73 Gary K4FMX _______________________________________________ ______________________________
Ok, thanks Mike. I now know what alternately means but I don't see how that will alleviate any torque issues on the mast. What am I missing? 73 Gary K4FMX ____________________________________________
Thanks Roger, I agree with what you are saying. The torque equalization could happen only if the wind was at the perfect angle. If a single antenna, or one on each side of the mast, were getting hit
Go to Mouser or anyone else that sells large MOV's. Buy a bunch of them. Put one to ground on each control line. That is ALL that there is in the Polyphaser rotor protector box. Keep in mind that the
I agree with you Jerry. What they fail to disclose is the amount of energy that is being dealt with. If the "propagation slows down via the coax" that doesn't change the amount of energy that has to
You got it, snake oil! The use of an independent down conductor on towers has been claimed by some to prevent current flow in the tower. Fat chance! The tower has much lower inductance than any down
I wonder what that response might have been?? Maybe there is something I don't understand but I see so many times those responders to a question do not post to the list. I can understand not wanting
I am working on a couple of T2X rotors and wondering if different value pots were supplied for the position indicator pot in the rotor? The manuals all say 500 ohms. I have one rotor that measures 50
Hi Red, Were you able to find different pieces of pipe to make the bushings or did you have to machine them? 73 Gary K4FMX _______________________________________________ ____________________________
The surface wave is what AM broadcast stations depend on for propagation of their signal. Vertically polarized signals at low frequencies, up to around 4 MHz, will follow the surface well beyond line
A 100 watt gun isn't going to solder a PL259. 73 Gary K4FMX _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting
Nope "you" ain't doing it right if you think you got it soldered with a 100 watt gun. You just can't get enough heat from one to do the correct job. With that size gun it takes much too long to get t
The connectors themselves usually do not directly cause losses of any significance. However at higher frequencies there is what is called "mismatch loss". The connectors provide an impedance bump in
Don, The easiest thing for you to do would be to install your panel as you propose where the cables enter the house and put the protectors on the panel for all the RF and rotor cables etc. Having the
Without actually seeing the installation I would recommend that you do a similar thing as I have described to Don below. It is not good to depend on a Ufer ground system as the primary ground system
If you have a west marine store nearby they will crimp them for you. 73 Gary K4FMX _______________________________________________ _______________________________________________ TowerTalk mailing li
You would be more correct in saying that he is the "self" appointed guru on the nec. 73 Gary K4FMX _______________________________________________ _______________________________________________ Tow
