One thing I've never been able to explain to people is: Why do the big Celwave, Sinclair, etc. "StationMaster" type antennas have only 5.2 dB gain? Actually, the 2-meter range ones are listed as typically having only 4.8 dB gain, after putting the longer, lower-frequency elements in the 22' long or so radome.
The typical 5/8 wave mobile antennas have "3 dB gain", some of the "ham-grade" antennas claim 7-8 (and even 10 dB gain). I occasionally get asked, why do you use one of those expensive, low-gain Sinclair, Celwave, etc. antennas instead of Hustlers, Diamonds, etc that have so much more gain? Even the big Scala OG-4 2-Meter antennas are 4 dB gain, if I remember correctly. I've always been at a loss to explain, but having tried some of these amateur antennas, I see quite a performance difference (for the better, of course) when I go back to using the "real" commercial-grade antennas. I'm sure there must be something simple that I'm overlooking.
