Comtelco antennas have an enclosed silver- plated phasing coil and feature a .125" diameter stainless whip below the coil. This gives us a more robust whip than units with only a .100"diameter whip.
Our High-Q loading coils are wound and 100% tested before and after assembly to insure proper operation. Our coils are larger diameter allowing Low Band coils to be built in the same low profile base as our Vhf and Uhf models. We have provided more frequency splits in our shunt fed base loads. This allows better frequency matching throughout the bandwidth.
Most of our black whips are epoxy powder coated so there is no chipping or flaking, a problem that is encountered with chrome. Comtelco introduced the first spring-loaded contact in a mobile antenna and continues to develop and improve this technology.
