I've been milling a few things over in my head and one thing that has
struck my mind and resonated is power versus modulation -- our 900MHz
repeaters typically use a +/-2.5KHz average deviation, which is smaller
than the VHF norm of +/-4.5KHz. At almost half the deviation, it would
seem that one would obverse an apparent increase in signal power of a
little less than three decibels.
Here's where I'm getting confused: Does 50W RMS at 950MHz over +/-2.5KHz
deviation mean the wideband (+/-4.5KHz) rating would be 25W? Does the
antenna manufacturer even bother to take deviation into consideration
when factoring power specifications? How does this factor in terms of
power wasted as heat (in the unlikely case that I'll attempt to put too
much power into an insufficently-sized radiator)?
