Fire-Flex cophase harness made from top grade RG-59A/U coaxial cable complete with three screw-on PL-259 connections. And, as a bonus for purchasing a complete kit, we throw in 2 FREE
stainless steel springs and a FREE
microphone hanger.
Co-phased (or dual) antennas are normally chosen for use by vehicle owners that spend much of their time on the interstate highways. Dual antenna systems create a transmission pattern that has increased field strength directly in front and behind the vehicle. This is especially helpful on vehicles pulling large trailers that tend to shield the antennas radiated energy in one or more directions. Co-phase antenna systems are also useful on vehicles that are lacking in ground plane (composite materials, etc.) as they use the magnetic field from one another as the RF field counterpoise. However, to work properly the antenna mounts MUST have a good chassis ground and the antennas MUST have unobstructed line-of-site between the top 50% or more of the antennas overall length.
