Hmmm, so Ubiquiti is just choosing not to publish the gain vs freq
information. Pretty much all dishes have a
gain?

Yes, but your return loss would have to be much worse than this to have a
noticeable effect.
Think of it this way: A 3dB RL
I always spec'd my gains as measured system gains with the RL effects, so
the gain I spec is the gain you get.

Yes, but
) means you are losing .457 dB.
Most antenna manufacturers shoot for 14 dB minimum.
That is a .17 dB loss of gain.

If a 5 GHz band antenna has
Don't forget to account for cable loss. Also, some of the old Rocket
dishes (23) are actually 21. I ran into that on the AF5X and that is the
info from support.

If a 5 GHz band antenna has a gain spec of 23 dBi and a graph of return loss
vs frequency, is there a way to translate this into gain vs frequency?
We put up an AF5x link today with the 23 dBi antennas and actual Rx signal
was 6 dB less than ideal. But that would make sense if the antenna gain
