Most of the consumer G gear has been pretty dreadful, at best, for P2P
links. It just isnt up to the job. Im getting some new Senao AP/Clients in
soon, and these should be quite good, if the B gear is anything to go on.
Exciting rumours of transmission power control  too I should mention.

Sure, there is a small matter of the law however. You cant legally exceed
36dB at the antenna, so a 25dBi ant, plus an 18dB AP is 43dB before cable
loss. way way way too much.

You buy them with a rgSMA to N male or female pigtail, and cabling as
appropriate.
