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. \u003cbr\u003e \u003cbr\u003e 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. \u003cbr\u003e \u003cbr\u003e - CD51 antennas are fitted with a flexible nylon radome over a copper element - ideal in industrial applications. \u003cbr\u003e - CD50 antennas have an elegant and durable tapered stainless steel whip section. \u003cbr\u003e \u003cbr\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. \u003cbr\u003e \u003cbr\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. The MBC base is easy to install and allows the entire antenna to be removed and replaced at will. \u003cbr\u003e \u003cbr\u003e • Versatile - Ground plane independence allows alternative mounting locations \u003cbr\u003e • Performance - High performance and largely omni-directional pattern when not centre roof mounted \u003cbr\u003e • Convenient - Patented design allows termination or retermination in seconds \u003cbr\u003e • Stainless steel whip or flexible nylon whips cater to individual needs \u003cbr\u003e • Durable - Base coil is virtually indestructible \u003cbr\u003e • Unique transformer design \u003cbr\u003e • Australian Patents #596830 and #656793 \u003cbr\u003e \u003cbr\u003e (Note 1) Mopole™ antennas such as the CD50 and CD51 exhibit a 4dB improvement in performance over a ¼ wave whip but in pattern tests deliver only 2.0 to 2.5dB of actual gain. 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. \u003cbr\u003e (Note 2) Available pre-terminated with 5m RG58.
