Thanks for the quick reply, I’ll give it a try and post results here. I just ordered a Surf SOHO so it will be a little while…
I don’t expect to use the 5 Ghz band, so I may go with these 12 dBi omnidirectional monsters. I’m using a sing AP for the entire house, so a potential problem with high gain antennas reduced vertical gain. At least, my understanding is that a trade off for higher gain is less vertical sensitivity, meaning less sensitivity to signals outside the horizontal plane of the antenna. I could angle the antennas, but then I’d lose the effective omni-directionality.
This setup is for a timber frame house with lots of open spaces, so the antennas will be mounted on a beam that is at floor level of the second story, dead center of the house. Maybe I’ll just test both low and high gain antennas and see which work best.
