The SG-237PORTA Smartuner designed for quick portable set-up or base operation. It is designed to match ladder feed or end fed antennas. The SG-237PORTA can be set up for temporary communications on a balcony or ground location, and is even small enough to be handheld. The power handling capability is 100W (PEP) and 40W maximum on CW. Its rugged internal constructionis ideal for tough operation. Only four connections are required. The DC input requirement is 13.8V DC (nominal) 300mA, its DC operating range is 10.5 to 18V DC. Any 2.7m (9ft) whip will provide good operations above 3.5MHz. For operation down to 1.8MHz it is recommended that at least a 8.5m (28ft) wire antenna or 6 x 6m (20 x 20ft) loop antenna be used. When using a whip antenna in a fixed location it is important that a ground system of radials be used.
