Diamond SS‑500 Wide Band Antenna Splitter/Combiner – 0.5–500MHz, 3x PL Female, 30dB Isolation, 0.8dB Loss


Trustpilot

The Diamond SS‑500 is a high‑performance wide‑band antenna splitter/combiner designed for flexible signal routing between antennas and receivers. It supports configurations such as two antennas feeding one receiver or one antenna feeding two receivers, making it ideal for amateur radio, monitoring stations and professional RF environments.

Using a wide‑band transformation network, the SS‑500 provides efficient impedance matching and excellent isolation between inputs. With insertion loss ≤ 0.8dB up to 200 MHz and 30dB isolation between inputs from 3–200 MHz, it maintains signal integrity while minimising interference and cross‑coupling.

Covering 0.5–500 MHz, the SS‑500 is suitable for HF, VHF, and UHF applications. Its compact, robust metal housing and PL‑female connectors make it easy to integrate into fixed or portable setups, ensuring reliable performance in multi‑antenna environments.
