No. A radial system prevents current flow in the earth by 
providing a much lower impedance path for that current. It also 
provides capacitive coupling to the earth for lightning, so it can 
improve lightning protection. For a lot of reasons, the best 
situation by far is to have all the grounds in any installation 
bonded together by a very low impedance path (beefy and short). 
And it also is generally best for minimizing receive noise.

Hi Guys,

I sure enjoy the great information shared on TT!

Question: since "The purpose of radials is to PREVENT transmitter current from 
flowing in the earth" 
then for better radiation efficiency would it be better to have the radials 
isolated from the lightning 
ground?
