Most vehicles end up with a forest of antennas because each system wants its own — VHF for the two-way, UHF for the fleet channel, another for cellular. The CD40 collapses that into one whip: it works across 136-155 MHz, 378–520 MHz and 698–960 MHz simultaneously, with no tuning, so a single 310 mm whip on a single NMO mount serves all three. This is the whip alone, to fit an NMO base you already have.

Available Options:

• CD40-136960-11 (Whip only)
• CD40-136960-43 (NMO Base + 5m cable)

Product Features:

• Three bands at once: 136-155 MHz VHF, 378–520 MHz UHF and 698–960 MHz.
• Nominal gain 0 / 3.8 / 3.2 dBi across the three bands respectively.
• Full-band tuned — no field adjustment on any band.
• Flexible over-moulded 310 mm whip: survives car parks, branches and wash bays.
• 50 W rating; vertical polarisation; NMO mounting; supplied as whip only.

Application Areas:

• Fleet vehicles running two-way radio and cellular from one mount.
• Emergency services and utility vehicles with mixed VHF/UHF systems.
• Any vehicle where roof space allows only one antenna.

Selection & Installation Notes:

• Ground dependent — unlike RFI's collinear range, the CD40 needs a metal ground plane. Mount it on the roof or bonnet, not on a fibreglass canopy or a bull bar bracket.
• Pick the VHF split first: this is the 136-155 MHz version. The other variant covers the alternative VHF band, and they are not interchangeable.
• The -11 is whip only and the -43 adds the NMO base and 5 m of cable — this one is whip only.
• Three bands on one feeder needs the radios kept apart: tell us what you are connecting and we will confirm the splitter or duplexer arrangement.
