I can explain that easy enough. 1) Two antennas properly phase gives twice the capture, so twice the gain, so that gives 3 dB extra 2) Two 5 kW transmitters has 3 dB more power than the other. 3) 3 + 3 = 6 Dave > I thought at the time that it was due to the power adding in the voltage > mode. > > For instance if you take a 1volt signal into 1 ohm you get 1 amp and 1 > watt. but if you take two 1volt signals and add them to produce a 2 volt > signal then you get 2 amps and 4 watts. > > Not sure if my logic is correct but the phenomena is real! > > > Corby > > _______________________________________________ > time-nuts mailing list -- [email protected] > To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts > and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
