RFI CD93-72-73 Elevated Feed Mopole 490-520MHz UHF Antenna, 5m Cable

RFI CD93-72-73 Elevated Feed Mopole UHF Antenna, 490-520MHz, 5m Cable (No Connector)

6.5dB gain with a ground-independent elevated choke. Supplied with 5m RG58 cable, no connector terminated.

Overview

The CD93-72-73 is a rugged elevated feed UHF Mopole antenna designed for reliable communication in the 490-520MHz frequency range. With 6.5dB gain and a stainless steel whip, this antenna delivers enhanced performance for professional two-way radio systems in mobile or fixed installations.

Its elevated choke design offers improved ground independence, making it ideal for use on a variety of mounting surfaces, including gutter and roof bar positions where a full ground plane isn't available.

This version is supplied with 5 metres of RG58 cable fitted, but no connector terminated, so you can fit the exact connector your radio needs.

Key Features

• 6.5dB gain means extended communication range over a standard unity-gain whip, for fleet operators who want more reach without stepping up to a full base-station antenna.
• Elevated feed design means ground-plane independence for installation flexibility, for vehicles being mounted on gutters, roof bars, or other non-ideal ground-plane positions.
• Stainless steel whip with black high gloss finish means maximum durability in outdoor conditions, for vehicles that live outside year-round.
• Supplied with 5m RG58 cable means one less thing to source separately, with the flexibility to fit your own connector.
• Stud mounted design means compatibility with a range of RFI mounting bases, for installers who aren't locked into a single roof-centre mount.

• Commercial vehicle installations
• Base station mounting

Other Bands in This Series

The CD93 series covers several UHF sub-bands at the same 6.5dB gain. If 490-520MHz isn't your operating frequency, see CD93-65-70 (400-420MHz) or CD93-72-70 (490-520MHz, no cable). The 400-420MHz option is a different frequency band, not a direct substitute, so pick the one that matches your licensed frequency.

FAQs

Does this need a large ground plane to work?
No, the elevated feed design is ground-independent, so it performs reliably even on surfaces with a limited ground plane.

Does the antenna include a connector?
No. It's supplied with 5m of RG58 cable already fitted, but no connector terminated, so you can fit the exact connector your radio needs.

What does 6.5dB gain actually mean in practice?
RFI rates the CD93 series at 6.5dB improvement over a 1/4 wave whip. Real-world pattern testing typically shows 1.5-2dB of actual gain, still a meaningful improvement, particularly in built-up areas and rugged terrain.

Where can this antenna be mounted?
Its ground-independent, stud mounted design suits a variety of mounting positions, including gutter mounts and roof bars, not just a traditional roof-centre mount.

Can Mobile Systems Limited install this antenna?
Yes. We supply, install, test, and support RFI antennas and complete two-way radio systems throughout New Zealand.
