The Diamond SP‑3000W Lightning Surge Arrestor provides high‑performance protection for radio equipment across an exceptionally wide frequency range of DC to 3,000 MHz. Engineered for reliability, it maintains an SWR of less than 1.1 and an insertion loss of under 0.2 dB, ensuring minimal impact on signal quality.

With a 200W PEP power rating and Type‑N female connectors, the SP‑3000W is ideal for HF, VHF, UHF, and SHF installations requiring robust lightning and surge protection. Its advanced discharge characteristics — including 1000V impulse discharge voltage, 6000A impulse discharge capacity, and DC230V ±20% retention discharge capacity — provide strong defence against transient spikes.

Compact and lightweight at 113g, the SP‑3000W offers excellent insulating resistance of over 10,000MΩ at DC100V, making it a dependable choice for safeguarding base stations, repeaters, and sensitive RF systems.
