Product Description
The Diamond SRH-771 is a high-performance dual-band antenna designed for handheld transceivers operating on the 144 MHz (VHF) and 430 MHz (UHF)bands. Thanks to its 40 cm length, it provides a clear increase in gain and signal range in both transmit and receive compared with stock antennas. With an SMA Maleconnector, it also offers excellent wideband reception on aviation and civil frequencies.
Key Features

Wideband Reception (RX)
Optimised performance also when listening on the 120, 150, 300, 450 and 900 MHz bands (including the airband). |
Light and Flexible Construction

Applications and Practical Tips
The Diamond SRH-771 is the ideal upgrade to increase the range of any handheld radio:
- Upgrade for V/UHF handhelds: An excellent replacement for poor-performing stock rubber whips, increasing coverage towards repeaters or in simplex use.
- Scanner listening and airband: Perfect for those who also use their handheld for receive-only on civil or aviation frequencies (120/150/300/450/900 MHz).
HRS tip: Before buying, carefully check your radio's connector. This model (SRH-771) has an SMA Male connector (with centre pin and internal thread). If your radio needs an SMA Female or BNC fitting, see the other versions in the Diamond range in our catalogue.

"Diamond's SRH-771 is without doubt one of the absolute benchmarks for those looking for a clear step up in transmit and receive performance from dual-band handhelds. The 40 cm length is immediately noticeable on weak signals, while keeping the renowned mechanical strength and build reliability of the Japanese brand."
