The only antenna that u-Blox themselves advertise for use with the
(eval) F9P module is an unassuming 28dB gain puck (ANN-MB, not seen it
anywhere for sale so far).  So I don't think that the gain matters very
much for this module unless you have to compensate for distribution
losses, at which point you'll probably end up with the more typical
35…41db gain figures for fiyed installation antennas.

Interestingly enough the antenna is mentioned in a comparison with two
other multi-band patch antennas here:

You can apparently buy one from their store, with or without an
accompanying F9P RTK-module.

Achim.
