RFI CD51-65-70 UHF Ground Independent Mopole 380 - 440 MHz - Threaded Stud

When the CD50-65-70 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.

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

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.

Notes: In order to boost radio signal the following components are required: Antenna, antenna mount, booster and cable. The antenna and booster must operate in the frequency band of the signal. Signal cable feeds signal from antenna to booster.

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 terminat...
