[VHFcontesting] OT Wireless microphones - but still VHF / UHF

[Mike (KA5CVH) Urich]

I bet someone here knows the answer.

I am looking for a formula on how to calculate gain (in dB) in a near
field environment by moving the receive antenna of the receiver for a
wireless microphone closer to the transmitter.  I have an individual
telling me moving the antenna 40' gives him +12dB.  Now if he's moving
it from 45' away to 40' away maybe so.  However I don't have a clue
where to even look for a formula.
