[CQ-Contest] Re: [TowerTalk] TH7DX INFO

[T. A. Russell]

Angle of radiation is a function of antenna height NOT boom length.

Yes, a longer boom (higher gain) antenna will have a narrower pattern
in the vertical plane but the high angle cutoff of both antennas is well
above the maximum angle that will propagate on the high bands so,
I repeat, the angle of radiation will be determined by the antenna 
HEIGHT and NOT boom length.
