Delivery Fees

All international orders incur a delivery fee. Within Australia, orders under the free shipping threshold also incur a delivery fee.

Product Info

Gap Setting Limits: 5 to 18 kV
Gap Capacitance: 1.0 to 0.3 pF

The Adjustable Spark Gap (DG PN 17245) is designed as a protection device to shunt lightning currents to ground, thus preventing high voltages and currents from damaging radio equipment.

The Spark Gap is designed to be installed near the antenna base and in parallel with the antenna. The Gap is adjustable from a breakdown voltage of 3 kV to 18 kV, by adjusting the screwdriver slug that is positioned inside the corona ball. The lock nuts under the corona ball must be loosened prior to adjusting the Spark Gap. The unit is factory adjusted one revolution out from the point of contact with the ground terminal, which represents a breakdown voltage of 5 kV.
