UHF Fiberglass Antenna with Ground Plane Kit 400-470MHz - Compact Base

In this review the UHF Fiberglass Antenna with Ground Plane Kit is assessed as a compact, weatherproof base antenna focused on reliable UHF performance for ham radio operators and emergency communicators. The bottom line: it is worth considering for anyone who needs a simple, durable 400-470MHz solution with a convenient SO239 connector and an included ground plane kit. The antenna's modest 2.5dBi gain and 100W max power make it a good, straightforward choice for repeaters, scanners, and mobile transceivers where a small footprint and easy mounting are priorities.

Key Features

• Frequency 400-470MHz: Provides solid TX/RX coverage across the common UHF band used by many GMRS, ham and repeater systems for dependable two-way communications.
• SO239 Connector: The UHF female SL16-style connector makes it easy to mate with standard coax and typical ham radio mounts without adapters in most setups.
• Durable fiberglass construction: Lightweight but rugged and UV-resistant, the mast resists corrosion and stands up to outdoor exposure on rooftops or walls.
• Ground plane kit included: Short and long whip elements are supplied to improve signal efficiency and help the antenna hit repeaters more reliably than a bare monopole.
• Indoor/outdoor versatility: Comes with a mounting bracket and hardware so it can be installed in attics, garages or on exterior mounts for flexible placement.
• Compact 17in length: The modest physical size makes it unobtrusive for mobile or rooftop installs while still supporting 100W max power for typical amateur or scanner use.

Who It's For

The antenna is aimed at hobbyists and emergency communicators who need a compact UHF base or mobile antenna that is weatherproof and easy to mount. Its 17in length, SO239 connector and included ground plane kit make it especially useful for ham operators setting up a small repeater feed, a mobile transceiver on a rooftop, or a scanner that needs improved reception.

Those who need high-gain performance for long-range fixed links or professional commercial applications should look elsewhere; this model is designed for convenience, durability and routine UHF use rather than maximum gain or specialized VHF-only installations.

Pros & Cons

Pros

• Durable fiberglass body offers weather and UV resistance for long outdoor life.
• Includes ground plane kit and mounting bracket for straightforward installation and improved efficiency.
• Works across the 400-470MHz UHF band with a standard SO239 connector for easy compatibility.
• Compact size and 100W max power make it suitable for many ham and mobile setups.

Cons

• Moderate gain of 2.5dBi is fine for local and repeater work but not for long-distance high-gain needs.
• Dual-band whip lengths are provided but true VHF performance will be secondary to the UHF focus.

Specifications

Our Verdict

The UHF Fiberglass Antenna with Ground Plane Kit is a sensible, value-oriented antenna for ham operators and emergency communicators who want a compact, weatherproof UHF solution with easy mounting and standard SO239 compatibility. It is not a high-gain specialist, but its durability, included ground plane and versatile indoor/outdoor installation make it a practical choice for improving local repeater reach and scanner reception.
