UHF Stubby Antenna 4-Pack

This pack supplies four compact UHF antennas covering the 400-470 MHz band with an SMA-Female connector. Each unit measures 4.5 cm and presents a 50 ohm impedance for handheld two-way radios. The set suits teams or individuals who need spare or replacement whips for compatible UHF FRS walkie-talkies.

Install by threading onto SMA-Male jack

Installation is a simple screw-on action onto any radio with an SMA-Male antenna port; no tools are required. The short stubby profile reduces snag risk but offers less gain than longer whips, so range may drop in fringe areas. Ensure the connector seats fully to avoid high SWR caused by a loose fit.

3 dBi gain handles close-range work

The 3 dBi gain and 20 W power rating cover routine on-site or outdoor communication where line-of-sight is clear. Performance tapers off in dense terrain or at maximum licence-free distances where a longer antenna would provide more aperture. Users needing extended reach should consider a full-length alternative.

Questions about this item

How can I confirm the stubby antenna is performing correctly after attaching it to my UV-5R?

After installation, verify clear two-way communication on UHF 400-470MHz channels; the 3dBi gain and 50 ohm impedance should provide reliable transmission up to 20W input power without restricting movement.

What comes in the package and are any additional adapters required for my BF-888S?

The box contains 4 SMA-Female stubby antennas measuring 4.5CM each; no extra adapters are needed for radios with SMA-Male connectors such as the BF-888S, UV-82, or Kenwood TK-260.

Which antenna version should I choose for a Retevis H-777S versus a Kenwood TK-270?

Both models use SMA-Male connectors and operate within the 400-470MHz UHF range, so the same 4-pack of 3dBi gain stubby antennas is compatible with either radio.
