Dual-band handheld antenna

The usbroway HYS-771N is a 15.6-inch dual-band antenna covering 144 and 430 MHz with an SMA-Female connector. It is built for operators of compatible handheld radios who want a flexible, high-gain whip for everyday carry and field use.

Gain and power handling

The antenna delivers 2.15 dBi gain at 144 MHz and 2.5 dBi at 430 MHz while accepting up to 20 W of input power. Its lightweight construction keeps the radio balanced during extended operation and the SMA-Female joint ensures a secure, low-loss connection.

Upgrade from stock rubber duck

This whip replaces the short factory antenna supplied with most supported handhelds, adding measurable gain on both VHF and UHF. The improvement is most noticeable when operating at the fringe of repeater coverage or in urban canyons; users who only work strong local repeaters may not justify the extra length.

Highlights

Questions about this item

How do I fit the SMA-Female connector on the HYS-771N, and what step do people often skip?

Screw the SMA-Female connector clockwise onto the radio’s SMA-Male jack until finger-tight; the step many miss is checking the centre pin seats fully before transmitting.

What maintenance or replacement will the HYS-771N need after extended use?

Inspect the SMA threads and centre pin for corrosion or bending; replace the antenna if the gain drops below the rated 2.15 dBi at 144 MHz or 2.5 dBi at 430 MHz.

What limit appears first when I run the HYS-771N at high power for long periods?

The 20 W maximum power input is the first limit; exceeding it risks overheating the antenna element and degrading the 2.15 dBi / 2.5 dBi gain figures.
