UHF Directional Yagi Antenna, 9 Element, 480–520MHz
The RFI YB9-62 is a high-gain directional Yagi antenna for fixed-site UHF communications, built for repeater links, telemetry, and SCADA networks. Oversize item: additional freight charges may apply due to its length.
Overview
The RFI YB9-62 is a 9-element UHF Yagi antenna covering 480–520MHz, engineered for fixed-site installations that need strong directional gain rather than omni-directional coverage. It's built for repeater systems, point-to-point radio links, SCADA, telemetry, and other critical communications infrastructure.
Its welded aluminium construction with an alodined finish keeps it corrosion-resistant on exposed towers and masts, and the full-band design means no on-site tuning is required. If your site doesn't need this much gain, the RFI YB6-62 (6-element, same band) is a lower-cost step-down option in this range.
Key Features
- 9-element directional Yagi design means concentrated RF energy in one direction for longer, more reliable point-to-point and repeater links, for network designers linking remote sites.
- Full 480–520MHz coverage with no tuning required means a straightforward install with one less variable to get wrong on site, for technicians commissioning fixed UHF links.
- 18dB typical front-to-back ratio means better rejection of unwanted interference from behind the antenna, for sites sharing spectrum with other UHF users.
- Welded aluminium construction with an alodined finish means it stands up to years on an exposed tower or mast in New Zealand conditions, for operators who need infrastructure that lasts.
- Rated to 100W input power means it handles serious repeater and base station transmit power without drama, for high-power fixed-site systems.
- N female connector with cable tail means a low-loss, high-power connection suited to permanent fixed-site installs, for network techs wiring up repeater sites.
Applications
- Repeater stations and point-to-point radio links
- SCADA and telemetry networks
- Utility and transport communications
- Mining and industrial radio systems
- Government and public safety communication networks
- Remote monitoring infrastructure
What's in the Box
- 1 x RFI YB9-62 9-element UHF Yagi antenna, N female connector with 9008 cable tail
- Mast/boom clamp sold separately, see Complete Your Setup below
Complete Your Setup
The YB9-62 mounts via a 100mm x 25mm diameter boom. The RFI UCR1 Antenna Clamp (20–52mm) is a likely fit for this mounting diameter, though we'd recommend confirming against RFI's mounting guide for your exact mast size before ordering.

Frequently Asked Questions
What frequency range does the YB9-62 operate on?
The antenna is designed for 480–520MHz UHF communication systems.
What are the advantages of a 9-element Yagi antenna?
A 9-element Yagi provides higher directional gain, longer communication distances, improved signal quality, and better rejection of unwanted interference compared with smaller directional antennas.
What applications is this antenna suitable for?
The YB9-62 is ideal for repeater systems, point-to-point links, telemetry, SCADA, utility communications, mining, transport infrastructure, and industrial radio networks.
Is the antenna suitable for outdoor installation?
Yes. The welded aluminium construction with an alodined finish is designed for permanent outdoor use in harsh environmental conditions.
Why is this listed as an oversize item?
Due to its physical length, the YB9-62 requires specialised freight handling. Additional shipping charges may apply depending on your location.
Can Mobile Systems Limited install this antenna?
Yes. We supply, install, align, test, and commission professional fixed-site antenna systems and complete radio communication networks throughout New Zealand.
