I have done my homework ... after all, I am vice-president of the homeowners' association for the community in which I live. All I'm saying is that K3AIR's painting of all homeowners' associations a

ANY vertical antenna, will perform better with a good radial system. Any vertical antenna in close proximity to ground will have a field that interacts with the ground such that any improvement in g

I don't have a model of the XR-5 but I do have models of the Cushcraft ASL-2010 "Skylog" and the Force 12 C3E. Both are 18 foot boom antennas making them the best apples to apples comparison I can c

One more time... this list does *NOT* use Majordomo software. It was converted to Mailman about six weeks ago. When the conversion happened, every user was sent a new "welcome message" with their pas

Does anyone has a source of the equations for designing coaxial traps ... and a source of RG-303 or similar coax? I'm starting an antenna system project that will require some traps and baluns. Coaxi

They do, if allowed to flex often enough! I lost more than one element tip (on a commercial antenna) before I learned the "rope trick" years ago. ____________________________________________________

I've used homeowner's insurance a few times and, in fact, a tower is no different than a detached garage, storage outbuilding, or barn ... as long as it is permanently attached to the land it is cove

Having done just this thing 25 years ago back in central Ohio, it works just fine. I went to the manuals to refresh my memory and here's how I did it ... 1) simply parallel wires 1,2,3,5,6,7,8 (this

Don's comments are on point ... If you are going to elevate the base of the vertical, go ahead and put in 60 or so normal quarter wave radials in the ground. THEN install four "flat" elevated radials

Unless the feedpoint is at least 1/2 wave above ground, you need the buried radials as W8JI and N7CL have pointed out on previous occasions.

I agree with Pete ... the KT-34XA was a maintenance headache for many people. The unbalanced 36 foot boom is also a problem for many under size towers and rotors. However, even the short boom versio

I have had an AB-577 here in Florida with a dipole (double size G5RV) only on the top for about two years. The bottom two sets of guy wires (top of the launcher and about 27') are installed but I hav

My concern would be for the wind survivability of the collapsible fiberglass tubes in the wind and high UV in Florida. With that concern I'll wait until the antennas have several years of fulltime e

There isn't (or should not be) much disagreement about the current in a coil. Quite simply, unless there is a significant loss - either I^2R or radiation - the current into and out of a coil must be

In addition, since the linear loading is often folded along and relatively close to the element, there is substantial coupling between the element and the loading. This results in cancellation in th

Get off your high horse. In a series circuit, which a loading coil most certainly is, the current into and the current out of a device must be the same. In the RF circuit, if the current into and out

Gary, That's climbing the main section ... the new/offset section is the shorter piece visible just to the left. At this point it looks like the tower has two sections in the main and one on the lift

Fluidmotion (SteppIR) do not do any rf measurement. The "automatic" mode reads the transceiver frequency from the data interface (it listens or "snoops") and then sets the element lengths from a loo

He said it was "R" rated ... if you were easily offended you did not need to open the site. If you opened the site, shut up! Now grow up or go back to listening to Jerry Fallwell. ___________________
