Diamond RH‑775 Dual‑Band Telescopic Antenna – 144/430MHz 2m/70cm, BNCP Connector, 41cm Extended/14cm Retracted


Trustpilot

The Diamond RH775 is a compact, high-performance dual-band telescopic antenna designed for 2m (144 MHz) and 70cm (430 MHz) amateur radio use. With a fully extended length of 41cm and a retractable length of 14cm, it features 8 telescopic stages for flexible deployment and portability.

Weighing just 35g, the RH775 delivers 2.15 dBi gain at 430 MHz, supports up to 10W FM, and maintains a 50-ohm impedance for efficient signal transmission. It uses a BNCP connector for secure attachment to handheld transceivers and scanners.

The antenna operates as a 1/4 wave on 144 MHz and a 1/2 wave radially less on 430 MHz, ensuring reliable performance across both bands. Additionally, it supports wideband reception across 120/150/300/450/800/900 MHz, making it ideal for monitoring multiple services.

Whether for field use, compact setups, or wideband reception, the Diamond RH775 offers versatility, portability, and dependable signal quality.
