B4KC 1/1: Palstar offers two different externally connectable baluns. Type B4000 1/1 has a transmission ratio of 1:1 and should be used for loads < 150 W. The B4000 1/4 OT as a 1:4 version is particularly intended for the case of medium-impedances, as is usually the case with the higher bands.
For use with Lo-Z antenna applications and center-fed wire antennas with open wire and twin lead transmission lines.
