I'm in the planning stages of a 1.3mi link. It's a NLOS situationdue to some trees and rooftops. I'm planning to use 2 x linksys WTR54GL units running DD-WRT. Based on the following calculations, using a 2400MHz Tx frequency, the 1.31mi distance, along with a 200mW Tx power, -80dBm Rx sensitivity, 1dB loss for connectors and cable, and 14dB antenna gain on the Tx and Rx, I get a Theoretical System Operating Margin of 23.5 dB. This is using a helical antenna, chosen because it is of a circular polarization and according to my research, the best for getting through and around obstructions. Now I may be incorrect on this which is why I'm asking here. The antenna specs can be found here : http://www.wade-antenna.com/Wade/Helical.PDF Would anyone care to comment on this setup? _______________________________________________ Talk mailing list [email protected] http://seattlewireless.net/mailman/listinfo/talk
