Model JCM-150 100-200MHz -3 dBi Gain 


Design Features: The JCM-150 VHF 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 VHF band 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 VHF jammer collinear antenna is supplied complete in assembled condition. This high gain jammer manpack antenna has smooth VSWR and constant Gain over the 100-200MHz VHF frequency band. The JCM-150 VHF jammer antenna consists of ultra corrosion resistant radiating elements and enclosed in ABS housing. The ABS has excellent transparency for Radio Signals 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. The antenna is designed with spring base mechanism so that it can fold/bend when hitting any obstacle especially in bushy areas. (The image shown below is without spring)
NOTE: Part # JCM-150-S with spring fitted at base. Add 100mm in overall length and add 250 Grams in gross weight.
