Model JCM-20-100 20-100MHz -15 dBi Gain 


Design Features: The JCM-20-100 Jammer manpack collinear antenna is rugged all weather model, enclosed in a ABS radome, uses high quality brass radiating elements and does not require any field tuning or adjustments. The compact size of omni-directional antenna allows easy handling, shipping and highly suitable for transmitting, receiving without having the requirement of multiple antennas. 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.
Constructions: The jammer collinear antenna is supplied complete in assembled condition. This high gain jammer manpack antenna has smooth VSWR 0ver the VHF 20-100MHz band. The JCM-20-100 jammer manpack antenna consists of ultra corrosion resistant radiating elements and enclosed in ABS housing. The ABS has excellent transparency for Radio Signal and mechanically Robust to support extra mechanical strength to the antenna.
Mounting: The high gain man pack jammer collinear antenna is designed & supplied Man-pack application. The high gain man pack jammer antenna uses N-Male termination at the base so that same can be mounted directly on the equipment/transmitter. Optional: The antenna can be supplied with spring base if required with additional cost.
NOTE: Part # JCM-20-100-S with spring fitted at base. Add 100mm in overall length and add 250 Grams in gross weight.
