I have 2 houses on my property and am about to set up a wireless
receiver in the other house. Since the Gateway and network adapter
will be about 75' apart through thick adobe walls, and since there is
another network adapter in a completely different direction, I figure
that a few dB omni directional boost might help. But there is quite a
few antennas out there to choose from and I KNOW that not all are as
good as they advertise.

Can anyone recommend a good omni directional 2.4 GHz antenna for my
Linksys network? eBay antennas are fine . . .

Thanks, MrBill
