How many radials for a vertical antenna
WebThe Battle Creek 160/80 meter antenna used by many DXpeditions in the past was well researched. Their radial field was something like 40 seventy foot radials laying on the ground. ... When putting radials down for a ground mounted vertical the radials are there to screen the RF currents from the lossy ground. WebThe antenna will be centered within an area approximately 18' x 18'. Paint a ~24" x 24" square onto the roof using aluminum-fiber roof coating. Give it time to dry. Get a radial-mounting plate (you know, the things ~12" square that have screws along the perimeter for attachment to radials).
