Cobham VOR/LOC ANTENNA
3101-80A-00 / 108-118 MHz
Product Overview
The VOR/LOC antenna P/N 3101-80A-00 is specifically designed for helicopter and light aircraft use, typically mounted on the tail boom.
This antenna set, of the 'Towel Bar' type, comprises two radiating elements connected via integral coaxial cable to a single BNC connector, providing a unified RF output.
Its aerodynamic design minimizes drag, and the antenna structure is exceptionally light yet robust, ensuring an omnidirectional azimuth radiation pattern.
All metallic components are DC-grounded to facilitate static charge flow and provide lightning protection.
The exterior is coated with a glossy white polyurethane finish, offering resistance to hydraulic fluids and other corrosive substances.
- Designed for use on helicopter and light aircraft
- DC-grounded to provide static charge flow and lightning protection
- Saves weight/reduces drag
- Proven design and reliability
