AS-49061 Monopole Blade Antenna

It is a monopole blade antenna encased in fused silica. This antenna type is inherently linear. The materials used in the construction of the antenna were chosen to minimize the effects of the severe environments.

A resin quartz composite heat shield was mounted to the antenna to make the antenna flush with the heat shield of the vehicle. The mounting flange can be modified to meet the mounting requirements of a particular vehicle.

Features:

Space Qualified
Linear Polarization
High Temperature
Flush Mounted
High Pyrotechnic Shock
Tunable
Ideal Flight Termination Antenna
