Dual-Band Coverage for Handheld Radios

This flexible antenna operates on 145 MHz and 435 MHz bands with 2.15 dB gain. It handles up to 10 W of power through a 50 Ω impedance. The SMA-male connector fits most radios with an SMA-female port. Vertical polarisation and omnidirectional radiation suit portable ham and marine use.

Replaces Stock Rubber Duck Antennas

The upgrade is worthwhile when the original antenna lacks dual-band coverage or shows wear at the base. A 2.15 dB gain increase can improve both transmit reach and receive clarity on congested channels. Users staying on a single band or needing higher gain for fixed installations will not benefit from this model.

Fits Common Handheld Models Directly

Compatible radios include Baofeng UV-3R, UV-100 and UV-200; Wouxun KG-UV6D and KG-UV8D; Yaesu VX-3R, VX-6R, VX-7R, FT-60R and FT-270R; plus listed Puxing, TYT, Zastone, Linton and Tonfa units. No adapter is required for SMA-female ports. Radios with BNC, K-type or proprietary connectors cannot use this antenna.

Questions about this item

What connector does the TC-669ET use to attach to the radio?

The antenna terminates in an SMA-male plug that threads directly onto any SMA-female handheld transceiver.

How do I install the antenna and what step is often missed?

Screw the SMA-male connector onto the radio's SMA-female jack until snug; the step often missed is not tightening fully, which raises VSWR and cuts radiated power.

When should the antenna be replaced?

Replace the antenna if the black radome cracks, the SMA-male threads strip, or VSWR climbs noticeably above the rated 2.15 dB gain level.
