Triple Ratio Switch Balun (TRSB)
The Triple Ratio Switch Balun (TRSB) provides isolation for balanced or unbalanced antennas and impedance matching over the 9 to 75 ohm range. A three position switch allows instant selection between 50:50, 50:25 and
50:12 ohm configurations. The TRSB is ideal for the Buddipole or other loaded portable dipoles, verticals, mobile antennas and beams.
Used in conjunction with the Buddipole it increases the flexibility of the system and facilitates operation on the lower bands such as 40, 60 and 80 meters.
The TRSB operates from 1.8 to 30 mhz at power levels up to 100 watts. Overall size is approximately 4.5" L x 3.1" W x 1.5" H and weight is 6.8 ozs.
The TRSB comes with BNC female connectors on both ends. Included with the balun is an adapter with 2 mini-banana jack leads (to plug right into the Buddipole center Tee) and a hook and loop strain relief.
