RFI CD50-68-73 UHF Ground Independent Mopole Antenna (450-520MHz) - Threaded Stud -S/Steel with 5m 8058 RG58C/U
When the CD50-68-73 gets mounted on a vehicle gutter or similar position, this 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.
The CD50-68-70 mounts 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.
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
• 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

Notes
(1) Mopole antennas such as the CD50/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 pre-terminated with 5m RG58 cable. Use -73 or -53 suffix to replace -70 or -50 suffix.
