Topband: Materials for Beverages?

Tue Aug 3 18:46:41 EDT 2021

N7QT & I verified that black ring screw-in insulators are too conductive 
for one or two transmit radials on 160m.  Lot's of arcs and smoke.  I 
now use the yellow 4" long barb wire insulators screwed to trees to 
support 160m elevated Tx radials.

Black may not be a problem with Beverage field strengths.
