RFI CD50 4dB Mopole UHF Antenna (450-520 Mhz)

RFI CD51 UHF Mopole antenna provides optimum performance with a largely omni-directional pattern. Due to the low angle of radiation inherent in the dipole antenna pattern, a 4.0 dB improvement in performance is typical when compared to a 3 wave whip in the centre of a metal roof.

The end fed design of the UHF Mopoles incorporates a truly unique transformer in the base section. In this patented feed assembly, the dielectric of the coaxial feeder cable is trimmed to a set length and then introduced into the coil in termination. The result is a precisely matched feed which is so consistent that tuning to frequency from a chart becomes a matter of course. This improvement in performance can be attributed to a lower angle of radiation and is of particular benefit to users in rugged terrain conditions and in heavily built up city areas. 

CD50 antennas have an elegant and durable tapered stainless steel whip section

There are two styles of mounting arrangements offered:

Stud Mount (CD50-68-73)

CD50-68-73 version mounts via a threaded stud and nut assembly. This means antenna and cable cannot be separated. The antenna can be easily terminated, tuned and re-terminated in the field using the instructions supplied. Its patented design allows the coaxial cable to be replaced in the field without specialised tools or soldering.

MBC Base Mount (CD50-68-53)

CD50-68-53 version mates with the MBC coaxial base providing an internal, permanent connection in a completely sealed unit. The MBC base is easy to install and allows the entire antenna to be removed and replaced at will.
