The Diamond SP3000W is a professional-grade coaxial lightning surge protector designed to safeguard sensitive radio transceivers, receivers, and network equipment from damaging electrical surges and atmospheric static discharges. Boasting an ultra-wide operational frequency range from DC up to 3,000 MHz (3 GHz), this high-performance surge arrestor is ideal for HF, VHF, UHF, SHF, ham radio, satellite, and high-frequency wireless communications. Featuring premium N-female connectors on both ports, it integrates seamlessly into high-fidelity, low-loss transmission lines.
This precision-engineered protector delivers outstanding RF performance, maintaining an exceptionally low Voltage Standing Wave Ratio (VSWR) of less than 1.1:1 and an insertion loss of less than 0.2 dB. These specifications guarantee that your system’s signal strength and overall integrity are preserved with virtually zero degradation. Capable of handling a maximum power rating of up to 200W PEP (Peak Envelope Power), the SP3000W is built to withstand high-energy transients, featuring an impulse wave discharge capacity of 6,000 Amps and an impulse wave discharge voltage of 1,000V.
For added reliability, the unit utilizes a high-quality gas tube element with a DC 230V (±20%) impulse wave retention discharge threshold and an exceptional insulating resistance of over 10,000 MΩ (at DC 100V). Physically, the SP3000W is housed in a heavy-duty, weather-resistant metal casing measuring a compact 78W x 41H x 20D mm (1″ x 1.6″ x 0.8″) and weighing just 113 grams (0.25 lbs). It is engineered for straightforward mounting and reliable grounding in both indoor and outdoor communication stations.
