Model JC-30-88 30 - 80 MHz -2 dB. Gain 
 

RCIED JAMMER ANTENNA

Design Features : The JC-30-88 Jammer Collinear Antenna is rugged all weather model, enclosed in a Fiber Glass enclosure, uses high class aluminum alloy and does not require any field tuning or adjustments. The N-Female termination of antenna is fixed at the bottom of NATO mounting base antenna to provide complete weather protection. This fiber glass jammer collinear antenna is specially designed to mount on the side of the vehicle with the help antenna adaptor base plate. The antenna uses standard NATO 4 holes pattern base which is suitable to mount the antenna directly on the antenna adaptor base plate. Similarly the antenna can also be supplied with pole mounting hardware (optional).Other customized mounting can also be supplied on request.

Constructions : The special co-axial stub and spark gap techniques are used for smooth VSWR and gain over entire the 30-88 MHz frequency band. The jammer collinear antenna consists of large diameter brass radiating elements stacked vertically, fed in phase and enclosed in fiber glass housing. The Fiber Glass has excellent transparency for Radio Signal and mechanically Robust to support extra mechanical strength to the collinear antenna. Cylindrical enclosure is used for low wind loading and for minimal effect of ice formation on the antenna operation as well as providing an aesthetically pleasing appearance. The antenna supplied with olive green colour for defence application.
