Our take on the RH-771 Dual Band VHF/UHF BNC Antenna

The RH-771 is a 38 cm telescopic whip antenna for handheld radios with a BNC socket. It transmits on 2 m and 70 cm (144/430 MHz) and receives across 120, 150, 300, 450 and 900 MHz, with a rated 2.15 dBi gain, 50 ohm impedance and a standing wave ratio under 1.2. It is a cheap generic part, so it suits owners of BNC radios who want a longer, more flexible antenna than the stock rubber duck. Compared with brand-name dual-band whips, it lacks published durability data and brand support, but the fold-over joint and telescopic sections are the features buyers look for at this level.

Questions and answers

Will it fit my handheld radio?
It uses a standard BNC connector, so it fits radios with a BNC socket. Radios with SMA or other connectors need an adapter.
Does it transmit on both bands?
Yes. Transmit is rated at 144 and 430 MHz, and receive covers 120, 150, 300, 450 and 900 MHz.
How much power can it handle?
The rated power is 10W. Keep within that on transmit.
How long is it?
It is 38 cm (about 15 inches) when extended, and the telescopic sections collapse for carrying.
Is it better than the stock antenna?
A longer whip usually gives more reach than a short stock rubber duck, but this is a generic part with no published gain or SWR test data.
Where is the RH-771 Dual Band VHF/UHF BNC Antenna cheapest?
At Walmart, for $11.99, as of our latest check.
