 Model SCD-243-318 243-318 MHz 3 dBil Gain 


Design Features SCD-243-318 SATCOM coaxial dipole antenna is an omni-directional antenna for vertically polarized waves. SCD-243-318 Omni-directional UHF satcom 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 satcom dipole antenna allows easy handling, shipping and highly suitable for SATCOM application without having the requirement of multiple antennas. The satcom dipole antenna features high suppression of skin current which provides the smooth VSWR over the 243-318MHz 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 satcom antenna is highly suitable for fixed station application, shipboard mounting and mobile application.

ConstructionsThe SCD-243-318 satcom 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 243-318 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 satcom antenna.
