Which connector type do I need?
Most handhelds use SMA-Female, SMA-Male or BNC — the specifications list the connector for each antenna. Send us your radio model if you are unsure.
Will a high-gain antenna improve my range?
A tuned high-gain antenna typically improves range and signal clarity versus the stock rubber-duck antenna, especially outdoors.
Are antennas compatible across brands?
Antennas are frequency- and connector-specific rather than brand-specific. Match the band (VHF/UHF) and connector to your radio.
