Standard Series

Lightning protector from Diamond or various manufacturers for in-line use; the protector can be used in the coax cable directly at the antenna base or at the radio. Available as N- or UHF connector, female/female or male/male, with a solder lug for ground connection. Available for various power loads, see table.
Diamond SP-1000
CA-35RP Diamond SP-3000

Please note: Normally the coax connectors are not waterproof; use coax seal (wrap it on like normal tape) and mold to fit!

Overvoltage protection for control lines

You should not only protect a coaxial cable against lightning, but also a control wire, e.g. of rotors, switches and antennas like SteppIR beams. With the device up to 16 wires of a control line can be easily protected against overvoltage. Just install the box at the base of your tower or at any other well grounded point and pass each wire oven one of the screw terminals. High-grade metal oxide varistors protect each individual wire, additionally a capacitor protects again HF induction of your transmitter.
