Antenna differences

I now have two antennas (soon to be three) with different gains. It would be nice to put in an approximate gain for the antenna used when submitting a stumble so that it could be used to weight the results for triangulation.

that's an interesting idea. have a spot for gain as well as amplification, maybe card used, etc. i'm not sure what the math would be to effect the triangulation. if you're driving in a straight line by a point i don't believe it's "triangulated" position would be different when using the weighted averaging I'm doing. hrmm...

Driving past the same point with two different antennas will give two relatively accurate IDW locations for the AP. Merging those to results via upload to WiGLE would seems to give bogus results because one antenna would say the AP was "closer" than the other one.

Yeah, that would be true if you have a non-linear driving path, when going around the block or something. I'll put the antenna strength on the todo list.
