UHF Standard Yagis
Price range: $255.19 through $748.65 inc GST
Hi-Tec Aerials standard series UHF yagis are cost-effective directional antennas for UHF CB, land mobile radio and telemetry links. Seven sizes from 2 to 12 elements let you match gain and beamwidth to the path, from short hops to long rural links.
- Y2U to Y12U: 3 to 11 dBd gain
- Four bands: 400–430, 430–450, 450–470 or 470–495 MHz
- Light, rear-mounted, 25 mm square boom, 100 W
- Supplied with a 1 m RG58 tail and N plug, no clamp
- Customisable: cable type, cable length, connector and mounting
Directional UHF on a budget
A yagi focuses signal in one direction, extending range to a distant repeater, base or telemetry site and cutting interference from other directions. The standard series is light and simple to mount, making it the go-to for farm and rural base stations, UHF CB links and SCADA/telemetry.
Choosing a model
- Short paths or wide coverage: Y2U (3 dBd, 145° H-plane) or Y3U (4.5 dBd).
- General links: Y4U (6.5 dBd) or Y6U (8 dBd).
- Long, difficult paths: Y8U (9 dBd), Y10U (10 dBd) or Y12U (11 dBd) for the most gain and narrowest beam.
- Band: 400–430, 430–450, 450–470 or 470–495 MHz. The 470–495 MHz band covers UHF CB.
For harsher sites, see our professional UHF yagis. For all-round coverage, see the UHF folded dipole. Two yagis can be stacked with a power divider for more gain.
Standard build and customisation
As standard, each yagi has a 1 m RG58 tail with an N plug and no clamp. You can customise:
- Cable: RG58 or RG58 Low Loss, any length (see coax cable)
- Connector: N, BNC, TNC, FME or unterminated (see connectors)
- Mounting: mounting clamps or saddle clamps, plus fascia mounts for houses and sheds
