This balun is designed for dipoles, inverted V antennas, and similar 50 Ohm feed designs.
The B4-2K 4:1 voltage balun is ideal for folded dipoles, delta loops or other medium impedance balance antennas where ATUs are not required.
The REM-BAL is is a 4:1 current type balun and is ideal for open wire to coax interfacing, especially external to the operating position. Unlike voltage baluns, current type baluns maintain output balance over a wide range of loads. Can be used with a transmatch.
The T-4Plus Line Isolator has been designed so that it can easily replace other Line Isolators. The isolation factor is nearly 150% of the original values available in early models, and the leakage path has been practically eliminated.
The T-4GPLUS is the grounded version of the T-4. The T-4GPLUS should be installed directly at a properly installed ground rod, or other station ground system. If you are using a vertical antenna, it should be installed right at the feedpoint.
The T-4-500 Line Isolator compliments the new line of Radio Works current baluns. Built to a high standard, the sockets are in fact silver plated with gold plated centre connection with PTFE insulation. Suitable for amateur and professional applications where up to 500W is used down coaxial lines. Provides excellent isolation while keeping losses to a minimum.
