The CD61 is the mopole you fit when the mounting surface is not on your side. It is ground plane independent — it does not need a metal roof under it — so it performs on a bracket, a fibreglass canopy or a plant enclosure where a conventional whip would not. Full 380-470 MHz coverage with no tuning, and a highly flexible over-moulded whip that shrugs off what a rigid element would not survive. This is the N female bulkhead version — it mounts through a panel and takes a cable you terminate yourself.

Product Features:

• Full 380-470 MHz coverage, no field tuning required.
• 4.0 dBq nominal gain; VSWR <1.7:1 (380-400 MHz), <1.5:1 (400-470 MHz).
• Ground plane independent — the reason to choose this over a conventional mopole.
• 276.6 mm highly flexible over-moulded whip; vertical polarisation.
• 25 W rating; N-type female bulkhead termination.

Application Areas:

• Commercial and government UHF fleets on mixed vehicle types.
• Plant, machinery and enclosures with no usable ground plane.
• Panel-mount installations where the antenna terminates directly at a bulkhead.

Selection & Installation Notes:

• This is a whip with a N-type female bulkhead — no cable is supplied. Order the feeder to suit your run.
• Match the band split to your licence: 380–470 and 450–520 MHz overlap but are separate parts, and the wrong one costs you VSWR.
• The N male (-60) and N female (-30) versions exist so you can avoid an adaptor. An adaptor is another joint, another failure point, and on a vehicle it will find the vibration.
• Ground-plane independence is the CD61's whole point — if you do have a good metal roof, a cheaper conventional mopole may serve. Ask us and we will say so.
