With the RFI CD40-148960-11, the answer is one. This multiband antenna covers 148-174MHz VHF, 378-520MHz UHF and 698-960MHz in a single whip, 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. This is the whip only: it screws onto an existing NMO mount, making it a straight swap for a damaged whip or an upgrade on a vehicle that already has an NMO base fitted.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour bands in one whip\u003c\/strong\u003e means one antenna serves 148-174MHz 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\u003eSingle compact profile (267mm whip)\u003c\/strong\u003e 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\u003e1 x RFI CD40 multiband whip (CD40-148960-11), whip only\u003c\/li\u003e\n\u003cli\u003eNMO mount and cable not included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eComplete Your Setup\u003c\/h3\u003e\u003cp\u003eThis whip needs an NMO mount to work.

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 148-174MHz VHF, 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\u003eWhat's the difference between the 148960 and 136960 versions?\u003c\/h4\u003e\u003cp\u003eThe two CD40 versions differ only in VHF coverage. The 148960 covers 148-174MHz and the 136960 covers 136-155MHz; both cover 378-520MHz and 698-960MHz UHF. Choose the one that matches your VHF channels.\u003c\/p\u003e\u003ch4\u003eWill this whip fit my existing NMO mount?\u003c\/h4\u003e\u003cp\u003eThis CD40 whip fits a standard NMO mount.
