Topband: Broadband Inverted L

[Joe Galicic]

Thanks Tom. I get the picture now. Time to go out and connect more radials directly to the feed point ground. I can also elevate two of them. -Joe

Ground systems cannot be evaluated or estimated by number of feet of wire, 
just like they cannot be evaluated by SWR or bandwidth, but I'm sure we all 
agree on this...... 

The single most important thing Joe said was: 

<<<< The antenna feed point terminates at a four foot ground rod and then I 
am running a number 14 wire from that ground rod to my existing radial 
field. That run is about 40 feet. >>>> 

Joes has virtually no ground at all on 160 meters, because his system's 
ground connection to the radials is via a single #14 wire 40 feet long. 

A 40 ft long wire laid on earth to the radials, even if Joe had 50 x 100 ft 
radials, would almost certainly make the ground path impedance hundreds of 
ohms. 

Joe's antenna virtually doesn't have a ground connection to radials at all, 
and this has almost nothing to do with the number of radials or type of 
radials. It has to do with the 40ft long connection.
