If you use the senao 2511 200mw card with 2 antennas does that mean each antenna gets 100mw power.

I'd have to look at the prints for it, but usually, one antenna is set up as tx/rx, and the second is set up as rx only. The card will pick whichever antenna has a better signal to listen to, but only uses 1 for tx.

Without getting the manual, I can only theorize, but you can experiment if you have a second PC to experiment with. Run kismet/netstumbler on 1, and unplug the antennas on the computer with the card installed. plug in 1 antenna and see if the signal suddenly jumps up on the scanning computer, then unplug it again, and plug in the other. 1 should spike, the other shouldnt. The pc's will need to be a decent distance apart though, if they're both on the same computer desk, they'll be close enough that even without an antenna, the scanner should pick it up.

A warning though, dont leave the antennas disconnected long, you run the risk of ruining the card because the antenna is part of the circuit.

I've always just used one pigtail per card w/ cards that have the 2 ports, making sure the pigtail was hooked up to the primary port.
