 Model JC3-1820 1800 - 2000 MHz. 3 dBi. Gain 


Design Features : The JC3-1820 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. This fiber glass jammer collinear antenna is specially designed to mount on the roof-top hole of the vehicle or can be supplied to mount the antenna directly on the jammer equipments. The JC3-1820 antenna is highly suitable for man-pack and vehicle mounting applications. Similarly the antenna can also be supplied with pole mounting hardware (optional).

Constructions: The special co-axial stub and spark gap techniques are used for smooth VSWR and constant Gain over entire the 1800 - 2000 MHz frequency band. The JC3-1820 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. The antenna supplied with olive green colour for defense application.
