BFC1 = Balanced DC Feed Choke; 7 T of #22 stranded PTFE twisted pair on an Indiana General #F624-19-Q1 toroid.
i = 125
RFC1 = 2 T of #18 stranded PTFE on a Fair-Rite #2677006301 shield bead.
i = 2000
T1 = 4:1 Z Conventional Transformer; 2:1 T of #22 stranded PTFE on a Fair-Rite #2843000202 Balun Core.
i = 850
T2 = 1:1 Z Transmission Line Transformer, using 50
coax.
Coax = 22" of mini 50
PTFE coax, OD = .095"
A large 2-hole balun core was constructed by gluing two Fair-Rite #2643102002,
i = 850 cores together.
The transformer is constructed by winding 4.5 turns of the coax around the center of the balun core.
