Power limits

[jwilkers]

While reading regs, I noticed only mobiles seem to be allowed the full 50 watts. They indicate "fixed stations" have a 15 watt max. I am then assuming base stations and repeaters are fixed stations under the rules.

 

Thoughts?

Those were left over from when fixed stations (and repeaters) had to be registered (pre-1988). There are a few legacy (businesses) operating under those licenses so the definitions remain in the rules.

Repeaters are subject to the same 50W (RF) power limits that mobiles are (notice, no defined ERP unlike the interstitial channels).

ok, thanks,

What is the max power for a base station??

[PastorGary]

95.1767 ( a) ( 1) - "The transmitter output power of mobile, repeater and base stations must not exceed 50 Watts."

 

 

[ As measured with properly calibrated equipment at the output connector on the radio or repeater, operating on the 462/467 MAIN channels.]

Fixed stations are also assumed to be those stations that only communicate with fixed stations; base stations are like fixed stations but intended to communicate with mobile units.  It's assumed that fixed stations will be using tight-beam antennas, while base stations will be using omnidirectional antennae.  The EIRP of the fixed station, even using only 15 watts, should probably be higher than the base station using an omni at the same range, so long as the beam antenna is pointed at you.

To clarify, in case anyone missed it: a "fixed station" is a specific type of station that is set up to communicate with another fixed station. The term does not apply to base stations nor repeaters.
