Balun Hybrids include an impedance balun (2:1, 4:1, 6:1, 9:1, 16:1, etc) and a 1:1 balun (choke) in a single enclosure. Use on OCF, loop, terminated dipoles and similar coax fed antennas requiring an impedance transformer Suppresses common mode current on the coax outer braid (prevents your dipole from acting as a tripole!).
Icom IC2KL, 4KL Standard RFI Kit
Included are the following chokes and installation guidelines:
RF Input: F240 toroid – 5-9 turns of RG-58 size through center
RF Output: FSB-1 (Big Clamp on) – 3 turns of RG-8 size cable
Relay Cable: FSB-1/2 – multiple turns through choke – ½” diameter hole
Transceiver Control Cable: FSB-1/2 – multiple turns through choke – ½” diameter hole
AC Power Line: FSB-1 (Big Clamp on) – 3 turns through center
Note to PW1 owners - use the DELUXE kit that has filters for all the I/O lines, 4 antenna outputs, and multiple input lines. See part # RFI-LA-PW1
