TWAYRDIO 7 Element UHF Yagi Antenna 11dBi 400-470MHz - Directional

In this review of the TWAYRDIO 7 Elements UHF Yagi Antenna the bottom line is simple: this is a focused, lightweight outdoor Yagi built for users who need higher UHF gain and better directionality for GMRS, amateur radio or satellite work. The antenna delivers an advertised 11dBi gain around 430MHz and a narrow beam that helps reach repeaters and distant stations; customers repeatedly note improved signal clarity and range after swapping from a stock whip or low-gain antenna. Assembly is straightforward and the corrosion-resistant alloy suits outdoor mounting.

Key Features

• Directional 7 elements: The seven-element design concentrates energy forward so users get stronger long-distance transmit and receive performance.
• 11dBi gain at 430MHz: Higher gain helps hit repeaters and maintain clearer contacts on GMRS and amateur UHF links.
• Rugged, lightweight construction: Antioxidant aluminum alloy offers corrosion resistance and strong wind tolerance while keeping the antenna easy to handle at 0.45kg.
• Compact three-section boom: The 985mm length in three sections makes transport and assembly easier while still providing a focused beam.
• Standard UHF female connector: The SL16/UHF female makes it compatible with common coax and radio installations without special adapters.

Who It's For

This antenna is best for radio hobbyists, GMRS users and small repeater setups who need a directional UHF solution that increases range and reduces interference. Field operators who want something lightweight and corrosion resistant for rooftop or mast mounting will value the simple assembly and U-bracket mounting.

Those who should look elsewhere include users needing wide omni coverage (this is directional), or those who require a built-in mast mount or larger commercial-grade antenna rated for continuous high-power installations above 100W; the unit is intended for general outdoor use and hobby to semi-pro applications.

Pros & Cons

Pros

• Good measured gain and front-to-back ratio that improves long-distance contacts and reduces unwanted signals.
• Durable, lightweight aluminum construction resists corrosion and handles strong winds well.
• Easy to assemble and tune from the supplied three-section boom and U-bracket hardware.

Cons

• Screw sizes for mounting have been noted as a minor pain point by some customers, requiring sourcing alternate fasteners.

Specifications

Our Verdict

The TWAYRDIO 7 Elements UHF Yagi is a solid value for radio enthusiasts and GMRS users who want higher directional gain without heavy hardware. It combines genuine performance benefits, corrosion-resistant construction and easy assembly, making it a practical upgrade for rooftop or mast installations where focused UHF range and reduced interference matter.

Frequently Asked Questions

Will this work for GMRS repeaters?
Yes; the 400-470MHz range and 11dBi gain make it suitable for many GMRS repeater applications when correctly mounted and aimed.

What connector and impedance does it use?
The antenna uses an SL16/UHF female connector and is specified at 50 ohm impedance.

Is it weather resistant for outdoor use?
Yes; the antioxidant aluminum alloy construction is lightweight, waterproof and corrosion resistant and the antenna is rated for strong wind conditions.
