Transmission Line Radiation

November 24th Fact-of-the-Day

All RF transmission lines other than waveguides and totally-shielded coax radiate some amount of energy. Transmission line radiation is undesirable because a portion of the energy sent to an antenna or a receiver is lost, because the lost energy may interfere with the normal operation of near-by receivers, audio systems, and other types of electronic equipment, and because the lost energy usually distorts antenna directional patterns to some extent. ©2004 Martek International All rights reserved.
