AS-309H Surge Arrestor
Operation and Installation
(For one or two wire transmission lines)
AS-309H Single Wire or Two Wire Arrestor
Rating 5 kW CW and Peak Power at High VSWR
– approximately 3000 V GDT
20 kA rated per tube
1 MHz to 60 MHz
Stainless steel hardware
Water-tight Nema-4X/6P harsh environment enclosure.
The main difference between this arrestor and others is the use of a static bleed component in
combination with a gas discharge tube (GDT). The high voltage bleeder in the AS-309H
suppressor is constantly draining static and voltage charge build up from the antenna. It also
relieves the gas tube from handling the current that would cause voltage build up and would
ultimately lead the tube to fire. This can happen before the gas tube conducts, as gas tubes
exhibit a delay. In addition, the suppressor appears as a mismatched load when a surge is
applied (combined operation of these components and gas tube) and much of the surge energy is
reflected back to the antenna. The antenna is also a mismatched load to much of the surge
energy, so some of that energy is reflected back to the surge arrestor, and goes back and forth.
In the process, the energy is dissipated in both the feed line and the arrestor.
