[TowerTalk] Dipole gain?

I agree that Free Space figures are probably the least ambiguous; but 
I'm not convinced that "averages" are very helpful!

What do we mean by "average"? What's the average of two F/B ratios, one 
of 10dB and one of 20dB?

[The average of 10dBW and 20dBW is 17.4dBW]

A "not worse than" figure across the bandwidth may be more meaningful.
