Lighting Chokes
Lighting chokes are used to pass tower lighting voltages across the base
insulator of a series-fed tower without appreciably altering the tower impedance. LBA
tower lighting chokes are provided for either two or three wire 110/220 VAC circuits.
Maximum current is 25 amps. These chokes are rated for peak base voltages to 10,000 volts,
and present a typical reactance of +j5000 ohms at 530 kHz. Bypass capacitors are provided
on each winding.
Lighting chokes should be protected from the weather. LBA Technology offers a small weatherproof aluminum cabinet with feedthrough insulator to accommodate outdoor mounting of these chokes.
Static drain chokes are employed to drain static discharges from towers before they build up to levels that could damage equipment. They are designed for installation in antenna tuning units and other equipment.
