[TowerTalk] Antennas questions...

[Richard Solomon]

I had a PRO-57A for many years and can attest that it DID NOT have
negative Gain on any Band. Now, they continuously "improved" the
antenna. Each revision seemed to make things worse.

Now, speaking from experience (as Program Manager on a number
of MM Wave Programs), an Antenna Test Range is not a trivial thing.
Look at the GE Test Range out near Rome, NY !!

I would be curious to know which antennas exhibited negative gain.
