Sinclair's SM300 and SM600 series of transport antennas specifically designed to address the need for compact, low profile, broadband antennas. These multifunctional antennas are single port which makes them easy to install. Given their broadband capabilities these models can serve multiple discrete RF systems when used with an cross band -coupler. SM 300 covers UHF-2500 MHz while the SM600 covers frequency bands between 746-2500 MHz. Designed to withstand constant vibration and harsh environments without compromising performance, these rugged antennas were designed and built for rooftop mounting.
