MORGAN SYSTEMS M-309 OPEN WIRE/BALANCED LINE ARRESTOR · Accessories & Components
A replacement, service, interface, or modular accessory for a documented product or system.
Why operators make room for it
MORGAN SYSTEMS M-309 OPEN WIRE/BALANCED LINE ARRESTOR: understand exactly where it fits in the station
Model 309 is designed for use with open wire balanced feed systems such as ladder line, window line, twinlead, etc. It is compatible up to it’s design power rating with a wide variety of input impedances / reactances ranging from about 300 ohms to 600 ohms Like all arrestor protection units these circuits are designed to be ground-mounted and should be installed close to earth entry point connections for best results. For transmitting or receiving applications using open-wire fed systems in single wire or parallel balanced lines, these arrestors use our patented technology in larger housings with insulated terminals. These units are constructed in metallic aluminum chassis cases.

Complete product details
For transmitting or receiving applications using open-wire fed systems in single wire or parallel balanced lines, these arrestors use our patented technology in larger housings with insulated terminals. These units are constructed in metallic aluminum chassis cases.
Model 309 is designed for use with open wire balanced feed systems such as ladder line, window line, twinlead, etc. It is compatible up to it’s design power rating with a wide variety of input impedances / reactances ranging from about 300 ohms to 600 ohms Like all arrestor protection units these circuits are designed to be ground-mounted and should be installed close to earth entry point connections for best results. Compatible with both split capacitor type antenna tuner and balun output stages common in modern antenna tuning products.
All units use toroidal inductors and present near dead DC short on antenna side of arrestor, constantly draining feedline wires of static and any developed voltage potential feedthrough breakdown voltage from input ports to output ports 4,000 to 6,000 volts. Arrestor units may be placed anywhere in the feedline at ground level without serious change in tuning, but small change may be detectable due “to small” increase in total feedline length caused by size of arrestor case & circuit.
Models 308 and 309 series all rated for frequency range 1-30 MHz, non-DC continuous through ports, polarized. Units 308 & 309 are constructed in aluminum cases with a mounting footprint of 4"x2", 1.875" tall. Units include a 2 page owner’s manual.
