With the RFI CD40, the answer is one. A single whip covers VHF, 378-520MHz UHF and 698-960MHz, so a multiband radio gets one clean install instead of a cluster of antennas on the roof.\u003c\/p\u003e\u003cp\u003eRFI's concentric radiator design keeps the VHF and UHF elements from fighting each other, so the pattern holds up across every band with no tuning required. The kit arrives with an NMO base and 5 metres of RFI 9006 cable, ready to install. The whip-only version screws onto an existing NMO mount, making it a straight swap for a damaged whip or an upgrade on a vehicle already fitted with an NMO base.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMultiband in one whip\u003c\/strong\u003e means one antenna serves VHF, 378-520MHz UHF and 698-960MHz, for fleets moving to multiband radios.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull band, no tuning required\u003c\/strong\u003e means no cutting or field adjustment on install, for technicians fitting out a whole fleet.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVSWR under 2.0:1 across more than 93.9% of the band\u003c\/strong\u003e means efficient power transfer from radio to antenna, for reliable talk-back at the edge of coverage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConcentric radiator design\u003c\/strong\u003e means VHF and UHF patterns stay clean instead of interfering, for consistent coverage whichever band is in use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible moulded whip on an aluminium base\u003c\/strong\u003e means it flexes with low branches, knocks and vibration rather than snapping, for vehicles working rural and forestry tracks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact profile\u003c\/strong\u003e (267mm whip on the 148-174MHz version, 310mm on the 136-155MHz version) means less roof clutter and fewer holes, for utes, response vehicles and fleet cars.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEmergency services and volunteer response vehicles\u003c\/li\u003e\n\u003cli\u003eCouncils, utilities and infrastructure fleets\u003c\/li\u003e\n\u003cli\u003eTransport and logistics fleets running multiband radios\u003c\/li\u003e\n\u003cli\u003eConstruction, forestry and rural vehicles\u003c\/li\u003e\n\u003cli\u003eOrganisations moving from separate VHF and UHF antennas to one multiband install\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNMO Kit (-43):\u003c\/strong\u003e 1 x RFI CD40 multiband whip, plus 1 x NMO base with 5m RFI 9006 coaxial cable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhip Only (-11):\u003c\/strong\u003e 1 x RFI CD40 multiband whip.

Any radio operating on licensed VHF or UHF land mobile frequencies in NZ needs a valid Radio Spectrum Management licence, and we can help you sort that out.\u003c\/p\u003e\u003ch4\u003eWhich radios suit the CD40?\u003c\/h4\u003e\u003cp\u003eThe CD40 suits multiband vehicle radios, including DMR, P25 and TETRA models, operating within its VHF band, 378-520MHz UHF or 698-960MHz. It also works with single-band radios in those ranges, which makes it a good future-proof choice if a fleet upgrade is coming.\u003c\/p\u003e\u003ch4\u003eDoes the CD40 need a ground plane?\u003c\/h4\u003e\u003cp\u003eYes. RFI specifies the CD40 as ground dependent, so it needs to be mounted on a ground plane such as a metal vehicle roof. Bare-metal contact between the mount and the roof matters too. If your install point is fibreglass or plastic, talk to us before ordering.\u003c\/p\u003e\u003ch4\u003eHow is the CD40 kit installed?\u003c\/h4\u003e\u003cp\u003eThe CD40 kit installs as a permanent NMO roof mount through a 19mm (3\/4 inch) hole. RFI recommends removing a narrow ring of paint around the hole for metal-to-metal contact, then tightening the locking nut to between 6Nm and 12Nm. We can fit it for you in the Bay of Plenty.\u003c\/p\u003e\u003ch4\u003eDoes the cable come with a connector?\u003c\/h4\u003e\u003cp\u003eThe CD40 kit comes with 5m of RFI 9006 cable on the NMO base.
