MIA: The Other Half of the Antenna and Cable Loss Equation, Kirt's Cogitation #288

For some inexplicable reason, it seems that of the most articles I read dealing with antenna and feedline efficiencies do not address the receive side of the equation. Yes, transmit power is expensive and there is a legitimate reason to reduce losses when converting power amplifier output to in-the-air power, especially for DX operations. However, it doesn't do much good to launch the full permissible 1,500 watts PEP and make a contact on the other side of the world if your system cannot receive a reply because of the excessive line loss and/or mismatch loss between your antenna and your receiver. Antennas and feedlines are reciprocal elements so if ... http://www.rfcafe.com/miscellany/smorgasbord/other-half-antenna-cable-loss-equation-kirt-blattenberger-smorgasbord-288.htm
