Topband: Radials on ground

[Artek Manuals]

Pete

I  was just  having this very discussion with some one else this week. 
We modeled a 100 ' tall T on 160 M with sixty-four 100' long radials 
using NEC-4. with that many radials there was essentially no discernible 
difference between #22 wire radials and #14 radials on average earth 
ground. If you want I'll run the analysis using NEC4 again against your 
smaller radial field later today. Give me the size of the vertical 
radiator(L, T or straight Vertical)
