Lloyd et all Isn't a BOG say 3" or 6" high draped over the weeds really now a very low beverage and not a BOG at all? It now needs to be longer and terminated to ground on the far end like you would a beverage in order to be effective? Wish the NEC4 engine wasn't so expensive I am getting

Topband: Using a Tower to Support an Inverted L

2019-08-25 Thread Udo A. Heinze
I just replaced my low 160 meter dipole with an Inverted L to improve my transmitting signal. The Inverted L is about 2 feet from a crank up tower I use on other bands. Here is the general layout: Tower height is 55 ft. On top is a 4 element WRC tri-bander and 8 feet above is a 2 element M2

Hello Mark! I did a similar thing a couple of years ago in order to run a BOG across the abandoned farm behind my property. Never doing that again! The following season I set the mower deck to maximum height on my lawn and garden tractor and drove thru the same field of six foot high weeds and

The comments in your first paragraph are very confusing, mixing up information on different antennas, old or proposed, and parts data, without clearly distinguishing what each comment refers to. I doubt that anyone will be able to sort that out unless they went thru the thread on QRZ.

I have never modelled an inductively-loaded Beverage, but my intuition is that it will not perform any better than an unloaded wire of the same physical length.   I haven't modeled for 10 years and even then I was in the dark.  I started on this quest when I saw this W8JI page about inductively

Not enough coffee earlier a better description of the radials: three 90ft radials radials  7'ft high spaced in 120 degree increments  (0, 120and 240 degrees) Another interesting side notes discovered while doing the modeling 1) A three radial version in a 180 degree half circle (0, 90 and 180)

Jerry et all My personal antenna FOR 160 was/is as follows 160M T:   60' Tall with with a 78' flattop. The "bottom"  is at 7' ( so the actual vertical element is 53') with three 90' radials at 7' spaced pretty nearly in 60 degree increments ( 60, 120, 240). There is a tapped inductor in
