Re: [AFMUG] Antenna gain vs transmit power

[Bill Prince]

The other issue is the distortion of the transmitter at the higher power. Amp output is linear through a range of power output, and when you get to the edges of the power envelope, they can start to distort.

You also assuming the CPE is in the main lobe (and that lobe shape isn't different between the sectors).

Antenna Gain > TX Power Gain.  Not only because it is bi-directional but there are plenty of benefits to increasing antenna gain and not TX power.

But as Adam said... a dB is a dB

A db is a db, but an antenna works in both directions and tx power only works in the tx direction.

So they'll perform the same in one direction only.

If you have two ptmp antennas with the same sector width and same model ap attached to them, and one antenna is 4 db less gain then the other. If additional 4db of transmit power is applied to the lower gain antenna, would the two sectors perform roughly the same? Is one db of radio transmit power truly equivalent 1 db of antenna gain, or is there more to it?
