Topband: Inverted L improvement question

[Dick Bingham]

Hello Guy (and the group)

I just finished reading your reply/observations on 160-Meter verticals - L's, etc - and wonder what your thoughts may be for the so-called "Half-Square" antenna (H-S) where the high current point is at the top of the array and the antenna is high-voltage-fed at the bottom.

I have a terrible QTH situation where ground conditions are very poor - basically river deposited gravel 
and sand sub-soaked by glacier and snow-melt water covered by several feet of organic matter. It is an electrically quiet area - S-0 or so - with noise basically all propagated non-man made noise.

The H-S antenna I use (actually a sloping H-S with top phasing wire at ~90-feet) has 5ea 136-foot radials and performs very well in contests using 100-watts or less. 

My question is, given the low current at-ground feed point with Zo ~ 2000-ohms or so, what sort of improvement might one expect if the radial field was significantly improved?

Apologies to all for delay in response.

Losses related to ground and close dielectric materials remain the
single monster gorilla in the room for improving TX performance of
vertical antennas
