Haven't said a blessed thing about your radials, which will make or break it. Someone talked about a problem with using a SteppIR on top of a loaded tower. Been a while and don't recall the particula
I think it would be good to do Yuri's famous picture with a coil of identical inductance, but that is evenly wound around a T300A-2 iron powder toroid, or the smallest that can create the inductance.
Probably the most useful thing to help in *visualization* of this phenomena is to remember that what is going on is a collection of electron moves, from one atom to the next. It is not the same thing
It would be of some considerable use to know exactly what you summarize in saying: I can guess what didn't work well, but I would rather hear your details. 73, Guy. __________________________________

"Probably" is, somewhere, at some price, and possibly with minimums. The RG6 style is sold in huge quantities, really a default feedline for many things. Digging required, unless you're lucky and som
One reason to use RG6 for burying, is that it is a lot easier to bury across lawns, etc. You can push it into a notch (as opposed to a trench) and just step on it. It's out of sight, and undetectable
I am assuming you have accurately ruled out more in-your-face problems, such as water-related problems in the loading coil, or the unun, or unintentionally bypassing some required element of the ante
Hmm, Don't get low angle, high angle confused with sky wave. Both low and high angle are sky wave, as opposed to ground wave which is a different mode of propagation that is always "local". You do no
If you are in a quiet location, you may find it difficult to hear better than your TX antennas, simply because they are not disadvantaged by the normal issues over flat ground. Vertically polarized s
Glad to have been of service. The way you model an antenna on a slope, is to SLANT the ANTENNA the same as the angle of the slope, if it's actually pulled true vertical, and then print out the plot.
For the part of the question before the "such as"..... Yes, you certainly can phase two reversibles, but you won't be able to do it unless you can insure that a "top" and "bottom," or + and - , or br
RF performance will improve with the number of radials, particularly because one of the duties of radials is to create a UNIFORM field around the base that is opposite and equal to the field from the
Well, not so quick. High end academic research on radials and related ground interactions effectively ceased in the 1940's when commercial broadcasting got their solution in FCC standards for commerc
I would also add that many times a SINGLE choke will not work and can actually make things worse. This is because miscellaneous capacity to ground, or actual grounding may be already minimizing the c

OR, if the choking need location NECESSARILY has a lot of voltage to block, and then perhaps a bifilar-isolation transformer wound on a low-mu powdered iron toroid (#2 ideally) would be better. I ha
The issue is going to be whether you can do it WITHOUT gaps, and how it will manage to last in normal eroding ground and weather conditions. Chicken wire is notorious for rusting out. If you could fi
Hi Mike, The following is assuming that you would not knowingly throw away dB on suboptimal 160 antenna construction, provided the issues were manageable in your situation. I have clear evidence, for
Hi, Mike Many transceivers do NOT have a separate input for a receive antenna, particularly older ones. For those rigs there are a few auxiliary boxes, like DXpedition II that pipe the one transceive
