BC antennas have the elaborate radial system in order to get that groundwave while the typical on ground ham vertical loses a lot of the 0-10 degree (or more) radiation. Go to the beach to get it back.....or go with elevated radials.



That just isn't factual at all. Radials under the vertical antenna have virtually no effect on wave angle unless they are sparse and grossly unbalanced, allowing them to radiate like a low horizontal antenna.

Radials change the efficiency, not the pattern, unless the radials radiate like a dipole.
