cooper Posted March 17, 2014 Share Posted March 17, 2014 So you've gone into full MacGyver mode and made your own antenna using some pieces of string, a wad of bubble gum and your trusty swiss army knife and lo and behold, the damned thing actually works... Now, you can obviously compare your homebrew antenna with any other by simply aiming it (assuming it's directional) at an AP and comparing the link quality using whatever tools and metrics you want. But how do you figure out what the actual gain of that antenna is? I've read one website that suggest it's a matter of taking your new antanna N, a second antenna G of which you know the gain it has and an accesspoint AP and set them up in a V pattern where the distance for both antennas to the AP is identical, take the S/N for the G antenna in this setup and the S/N for the N antenna and then compute the gain. My problem with this would be that I don't actually have a good known gain antenna. Just some flimsy low gain El Cheapo 'came with the device' type antennas. Is there an alternate way?
