Topband: Re: Topband: chicken wire ground screen (reply)

Well sayed and easy to demonstrate.
A surplus thermocouple ammeter will indicate the current flowing, 
either in the a metal screen just below an antenna or in a set of 
radials that extend away.
Users with inductive antennas, i.e. some inverted L or top loaded 
structures should be aware that their radials should extend more than 
with classical 1/4 or capacitive (short) antennas.
