Tower, Antenna and: Transcript

Feedline Maintenance and Improvements Improving the competitive performance and long term reliability of your tower antennas and coaxial cables Frank Donovan W3LPL. Protection Rules. Cris Alexander, CPBE, AMD, DRB. Crawford Broadcasting Company. Aurora, Colorado. Introduction. It has long been recognized that metallic structures near AM radiators have the potential to produce undesired effects on the radiation pattern. Typically the diameter of the ground plane should be at least 3.. λ. /4. The parameters of helical antenna are-. D- diameter of a turn on the helix antenna.. C- circumference of a turn on the helix antenna.. Protection Rules. Cris Alexander, CPBE, AMD, DRB. Crawford Broadcasting Company. Aurora, Colorado. Introduction.
