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. \u003c\/span\u003e \u003cbr\u003e \u003cbr\u003e \u003cspan\u003e The end fed design of the UHF MopolesTM 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. \u003c\/span\u003e \u003cbr\u003e \u003cbr\u003e \u003cspan\u003e CD51 antennas are fitted with a flexible nylon radome over a copper element - ideal in industrial applications. \u003c\/span\u003e \u003cbr\u003e \u003cbr\u003e \u003cspan\u003e There are two styles of mounting arrangements offered. The CD50-xx-70 and CD51-xx-70 versions mount via a threaded stud and nut assembly. 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. \u003c\/span\u003e \u003cbr\u003e \u003cbr\u003e \u003cspan\u003e The CD50-xx-50 and CD51-xx-50 versions mate with the MBC coaxial base providing an internal  permanent connection in a completely sealed unit.

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. \u003c\/span\u003e \u003cbr\u003e \u003cspan\u003e (2) Available preterminated with 5m 8058 RG58C\/U.
