4:1 Yagi Balun
The Centaur Yagi Baluns are specifically designed to mount on a Yagi antenna boom. Be sure to mount the Balun on the TOP side of the antenna boom with the balun's stainless steel dowell pins positioned directly upward. This will ensure that the condensation drain holes on the opposite side of the balun will be at the lowest point for proper drainage of water.
Centaur Yagi Baluns come equipped with a stainless steel band clamp and two mounting pads to attach the balun. The clamps have predrilled keying holes which fit the stainless steel dowell pins. Additionally, the mounting pads are included to prevent over tightening of the mounting bands. Do not over tighten the mounting bands.
The Centaur 4:1 Yagi Balun is ideal for antennas with a feed point impedance of 200 ohms. Typically the balun is fed with 50 ohm coax and then a short 16 gauge wire to the feed point. The 4:1 designation comes from (50 X 4 = 200) thus the feed point impedance is four times the impedance of the coax.
