RFI CD51-65-73 UHF Ground Independent Mopole 380 - 440 MHz - 5m Cable

When the CD51-65-73 gets mounted on a vehicle gutter or similar position, these UHF MopolesTM provide 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 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.  

CD51 antennas are fitted with a flexible nylon radome over a copper element - ideal in industrial applications.  

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 retermination in seconds
• Flexible nylon whip (black)
• 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. Use -73 or -53 suffix to replace -70 or -50 suffix.
