[Antennas] Vertical Phasing

[Larry Walker (KW4A)]

Getting ready to install a pair of Hy-Gain Hy-Towers and want all the
knowledge I can get on phasing these. Would like to cover 160, 80 and 40.
Whose has the best phasing hardware Array Solutions or Comtek. Are there
others out there as good or better? Optimum number of radials?  Radial wire
type and size (does it make a difference?)

Any thing else I need to know before I plant these suckers??

Tnx es 73s
