[Antennas] gain vertical

[CBoone]

What Clete refers to is downtilt...which can be done mechanically or
electronic...
Electronic downtilt or beamtilt affects the entire pattern (looks like an
umbrella then :)....physical tilting affects in only in one direction..in
the other direction it is UP tilted :)
