Filter Power Rating (PEP watts): max coax cable rating

RFI Suppression Range (MHz): 1-600 MHz

# Ferrite Filters: 7

Typical Use:: AC/DC power, RF In/out (x3), Control Lines

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.

When considering solutions for AM broadcast (550 Khz – 1.8 Mhz) you should consider Mix 77 ferrites available in a variety of shapes and sizes. Choose a size to give the maximum number of turns of the affected wire or cable.

AM broadcast transmits on a low frequency with large antennas. Consequently it takes a large antenna to receive the signals. Typical “antennas” are AC house wiring, phone lines, long satellite or cable TV cables, DSL/CAT5 lines running between rooms, etc. The device wires that connect to these “antennas” need to be choked with as many turns through the ferrite as possible. Some installation examples are shown below on this page.

For AC/ DC power cords and coax cables the F240-77 (2.4″ OD, 1.4″ ID) “Donut” toroid is the most popular. Also available are smaller toroid donuts and Mix 77 beads. Shown below is a graph with 8, 10, and 12 turns through the toroid – obviously more turns has higher choking impedance. Mix 77 toroid products are HERE and Mix 77 small beads (for small wires) are HERE
