RFI CD50-65-73 UHF Grd Ind. Mopole 380-440MHz-S/Steel with 5m 8058 RG58C/U

When the CD50-65-73 gets mounted on a vehicle gutter or similar position, these UHF MopolesTM provide optimum performance with a largely omnidirectional 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 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. 


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

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. 

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.

Features: 

  • Versatile - Ground plane independence allows alternative mounting locations

  • Performance - High performance and largely omni-directional pattern when not centre roof mounted• Convenient - Patented design allows termination or re-termination in seconds

  • Stainless steel whip or flexible nylon whips cater to individual needs

  • Durable - Base coil is virtually indestructible

  • Unique transformer design

  •  Australian Patents #596830 and #656793(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.(2) Available preterminated with 5m 8058 RG58C/U.
