Grant and all, The lingering problem with this, like with many other things in life, is that the time or effort required for good verification of a theory or idea is much larger than the time or effo
I can't believe that no one has put this really important question to bed already. Since the results vary with installation and soil, and since no one considers "it depends" a good answer, the debate
1) If you have the space and work hours and money isn't an issue - go with 120 1/4 wave buried radials. That is a myth that stems from the FCC not requiring a ground system proof of performance when
I've noted your postings re elevated radials to replace deteriorated buried radial fields under broadcast towers. I'm familiar with the work and the results. This work, of course was done by professi
This reminds me of an experience I had with a new antenna. After working several days installing a new antenna, I attached it to an a/b switch to compare it with my old antenna. I was delighted, the
The life of aluminum not only depends on the environment and the particular aluminum alloy, but also the electrical potential it is connected to. It can be especially bad in the presense of chloides,
I use CATV hardline everywhere here and have had some left over bare coils on the ground for the 24 years Ive been here. Except for staining from leaves, etc it is still fine appearing. The ground is
Depends on the method used to provide the conductivity. If it's carbon black filled, the shrinking is goin g to push the molecules of the carbon black closer together and that results in a net decrea
Been reading in ON4UN low band dxing book about mulitable element receive arrays for 160 meters. I'm a little confused about 180 deg phase inverters, and flip transformers are these two the same thin
Being in outside repair with ATT for 40 years, I had plenty of experience with attempting to seal closures. First of all if the closure, splice or what have you is NOT encapsulated it will get wet. E
What is the preferred method of tuning elevated radials for uniformity? Jeff and all, It takes two halves of a system to make a whole system. This means the vertical affects the radial resonant lengt
I wouldn't attempt to tune the radials exactly to resonance, because that will be most difficult to achieve due to a number of reasons... the worst that may happen is that just one radial is exactly
I'm having a repeated weird problem with compression F connectors on quad-shield RG6. When I connect a short length (say 4 feet) of cable to my MFJ-259B, I would expect R>650. Instead, when I wiggle
How about folding the shields back a little? I think that's a superior way of doing it as opposed to cutting them all flush with the jacket. Be careful doing that or using any non-approved assembly m
CATV installers use almost 100% quad shield in order to keep the signals inside and not cause interfering leakage (egress); FCC specs are adamant about that. These specs go back to the 70's. In more
What role does skin effect have in this situation - at 1.8 MHz? Skin depth isolates the outside and inside, virtually nothing passes through a conductor wall that is several skin depths thick. This i
I'm interested in your comment about LMR400 and soldered braids, Tom. I understand the point about shield current flowing on the insde of the foil or braid closest to the center conductor, but if the
Shouldn't you also look at lightning activity on the path between you and your area of interest? I've found quite often that the day after a big eastward-moving storm, there is a lot of noise on my p
After looking at their literature it appears to me that this is nothing more then two beverages, one in each direction, with the "feed unit" being, perhaps, a couple relays. I don't see the merit in
Go to http://exax.net/index.html and scroll down the page to "center fed steerable wave antenna". The diagram shows how you can feed a 2-wire Beverage in the center, or anywhere along its length. The
