 Model JCD-0820 800-2000 MHz 2 dBi Gain 


Design Features : The JCD-0820 Jammer coaxial dipole antenna is rugged all weather model, enclosed in a ABS radome, uses all ultra corrosion resistant aluminum alloy 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 including 800/900MHz GSM, GPS L1, GPS L2 and 1800/1900MHz GSM bands 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 coaxial dipole antenna is supplied complete in assembled condition. This discone antenna has smooth VSWR and constant Gain over the 1200-1600 MHz frequency band including 800/900MHz GSM, GPS L1, GPS L2 and 1800/1900MHz GSM bands. The JD-0820 jammer discone 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 jammer antenna.

Mounting : Following four options are available to choose from:
(1) Standard NATO 4 holes pattern for military vehicle. (2) Roof-top hole mounting on the vehicle which requires a 16mm hole through roof of the vehicle with N-Female termination. (3) Man-pack mounting; in this you can mount the antenna directly on the equipment with M-male termination. (4) Antenna can be supplied with pole mounting hardware; in this the mounting hardware is suitable for mounting on any outer diameter pipe between 32-51mm.
