Topband: 5/8 vertical

Yes, As current radiation is raised in the vertical, longer radials are 
needed.

Horizontal antennas are seldom used on 160 meters and below.  The up to 6db 
ground reflection for horizontals up 1/2 wavelength experienced on higher 
frequencies is attenuated by ground penetration.
Cave explorers have taken advantage of low frequency ground penetration to 
communicate  via radio with the surface, within limits.

 got a question..if using a 5/8 wave vertical should the radials also be 5/8 
wave long i guessing yes they do...John K1GUN
