 Model JCD-300-3000 300-3000 MHz 2 to 0 dBi Gain 


Design Features : JCD-300-3000 coaxial dipole antenna is an omni-directional jammer antenna for vertically polarized waves. JCD-300-3000 Omni-directional coaxial dipole jammer antenna is rugged all weather model, enclosed in a ABS radome, uses ultra corrosion resistant aluminum alloy and does not require any field tuning or adjustments. The compact size of omni-directional coaxial dipole jammer antenna allows easy handling, shipping. The coaxial dipole jammer antenna features high suppression of skin current which provides the smooth VSWR over the 300-3000MHz frequency band. 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. Due to sturdy design the and wide bandwidth the coaxial dipole jammer antenna is highly suitable for fixed station application, shipboard mounting and mobile application without having the requirement of multiple antenna.

Constructions: The coaxial dipole jammer antenna is consisting of round diameter radiating elements stacked vertically and enclosed in ABS radome. The special “Choke and Spark Gap” technique is used for constant superior performance over the entire 300-3000 MHz. frequency band. The UV resistant ABS enclosure has excellent transparency for RF signals and enough strength to withstand specified wind loads. The N-Female termination of antenna is fixed at the bottom of the mounting pipe for complete weather protection. The marine grade type 316 stainless steel mounting brackets are supplied with the coaxial dipole antenna. Standard NATO 4 holes pattern for vehicular mounting or vertical pole mounting option are available.
