Retevis RHD-771 · Product source ↗The RHD-771 is a flexible dual-band handheld antenna for VHF/UHF. Retevis offers the family with different SMA connections, so connector gender and mechanical fit must match the particular radio.
For its published SMA-F version, Retevis specifies 144/430 MHz, 50 Ω and power handling up to 20 W. The manufacturer page gives an approximate length of 39 cm, while the antenna in this collection was identified as 37.5 cm. This difference is retained explicitly rather than treating both versions as identical.
