Ruggedised UHF Directional Yagi Antenna, 6 Element, 400–420MHz
The RFI RDA6-65 is a ruggedised, high-gain directional Yagi antenna for fixed-site UHF communications, built for repeater links, telemetry, and SCADA networks in demanding environments.
Overview
The RFI RDA6-65 is a 6-element ruggedised UHF Yagi antenna covering 400–420MHz, delivering 10dBi of directional gain for point-to-point links, repeater systems, and other fixed-site communications infrastructure. If you need more gain, the RFI RDA9-65 (9-element, same band) is the step-up option in this ruggedised range.
Its heavy-duty welded aluminium construction with a black powder-coated finish is built for coastal, alpine, and industrial sites where standard antennas struggle. The full-band design means no on-site tuning is required.
Key Features
- 6-element directional Yagi design, 10dBi gain means concentrated RF energy in one direction for longer, more reliable point-to-point and repeater links.
- Full 400–420MHz coverage with no tuning required means a straightforward install with one less variable to get wrong on site.
- 20dB front-to-back ratio means strong rejection of unwanted interference from behind the antenna, for sites sharing spectrum with other UHF users.
- Heavy-duty welded aluminium with black powder-coated finish means it stands up to coastal, alpine, and industrial conditions where lighter-duty antennas fail early.
- DC-grounded elements means built-in protection against static build-up and help dissipating a lightning strike, for exposed mast-top infrastructure.
- Rated to 100W input power means it handles serious repeater and base station transmit power without drama.
- N female connector with weather-resistant cable tail means a low-loss, high-power connection suited to permanent fixed-site installs.
Applications
- Repeater stations and point-to-point radio links
- SCADA and telemetry networks
- Utility and transport communications
- Mining and industrial radio systems
- Local government and public safety communication networks
- Remote monitoring infrastructure in coastal or alpine locations
What's in the Box
- 1 x RFI RDA6-65 6-element ruggedised UHF Yagi antenna, N female connector with short 9302 cable tail
- Mast/boom clamp sold separately, see Complete Your Setup below
Complete Your Setup
The RDA6-65 mounts via a 100mm x 32mm diameter powder-coated aluminium 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 RDA6-65 cover?
The RDA6-65 is designed for professional radio systems operating between 400MHz and 420MHz.
What is the gain of the antenna?
The antenna provides 10dBi of directional gain, making it ideal for long-distance point-to-point links and repeater applications.
What is a Yagi antenna?
A Yagi antenna is a directional antenna that focuses radio energy in one direction, increasing communication distance and reducing interference compared with omnidirectional antennas.
Is the antenna suitable for harsh outdoor environments?
Yes. The welded aluminium construction and durable black powder-coated finish are designed to withstand harsh weather, vibration, and demanding outdoor conditions, including coastal and alpine sites.
What connector does the antenna use?
The RDA6-65 is fitted with an N female connector and a weather-resistant cable tail for reliable outdoor performance.
Can Mobile Systems Limited install this antenna?
Yes. We supply, install, align, test, and commission professional fixed-site antenna systems, repeater infrastructure, and complete radio communication networks throughout New Zealand.
