All coax I/O and control lines and AC/DC power line for high end amplifiers with multiple RF inputs and outputs, control/keying/frequency I/O.
Includes typical amps such as Yaesu Quadra, Icom PW1, ACOM, ALPHA,Tokyo High Power, Palstar, ETC.
Included are the following chokes and installation guidelines to suppress RFI in and out:
Deluxe Kit:
RF Input (1x):Ring Filter (1.4” ID) – 5-9 turns of RG-58/8X size through center
RF Output (3x):Snap On Filter (1” ID) – 3 turns of coax cable through center
Relay/ALC Cables (1x):Snap On Filter (3/4” ID) – multiple turns through center, both cables in same ferrite
Band Control cable:Snap On Filter (3/4” ID)- multiple turns through filter
AC/DC Power:Snap On Filter (1” ID) – 3 turns of power cord through center
You get 1.4" ID Ring x 1, 1" ID snap on x 4, 3/4" ID snap on x 2 with each kit.

50 ohm coax to 75 ohm balanced output baluns are useful for low (< 1 wavelength) dipoles exhibiting 75 ohm characteristic impedance or for matching to balanced ladder line whose endpoint impedance is near 75 ohms.
50 ohm coax to 75 ohm CATV coax connections are easily done with a 1.5:1 unun with SO-239 connectors on input and output. Likewise 50 ohm coax to unbalanced verticals or loads near 75 ohms can be matched with a 1.5:1 unun.
