Are there available any good experiences with 1:4 Guanella (current) balun,
consisting of 2 separated coax air coils (1:1 baluns) on TopBand with high
power ?
Do the coils should have any coupling (capacitive or inductive) ?
Are air coils useful instaed of ferrite core coils ?
Are coils of 50 ohm coax useful or should I use 100 ohm wire to transform ~ 200
ohm into ~ 50 ohm ?
Thank You in advance.
