1) Transmission
Coax Cables
Between transceiver and power amp and,
power amp and antenna.
Use a larger ferrite core and make loops
or use a few cores (or more as you
experiment), close to
transmitter/transceiver/power amp.
Mode#31500
Fits:
RG-214, RG-213, RG-8,
9913, LMR400 or smaller
Model#311000 Fits:
RG-214,
RG-213, RG-8, 9913, LMR400,
LMR600, LMR900 or smaller
You
can make 3 loops over 9913 type
flexible coax.
2) AC Power Lines
AC-DC power supply and AC power lines on
transceiver and power amp
Use a lager ferrite core and make loops
or use a few cores, close to power
supply unit.
Mode#31500
Fits:
12AWG/3C,
14AWG/3C, 16AWG/3C, 18AWG/3C or
samller
You can make a loop over 18AWG/3C (typically used for PC’s) power
cable.
Model#311000 Fits:
12AWG/3C,
14AWG/3C, 16AWG/3C, 18AWG/3C or
smaller
You can make 3 loops over 14AWG/3C (typically used for hi-power
HF
amp’s).
3) DC Ground Lines
If separate DC ground is connected, use
a ferrite core (Model 31500) and make
loops (you can make 3 loops over
10AWG-strand), close to
transceiver/power amp/tuner/etc.
4) Accessory Cables
When RF feedback exists, use a ferrite
core (Model 31500) with loop(s) on cable
connected to affected equipment. This
may include mic, computer interface and
other accessory cables.
NOTE: Ferrite core Model#311000
is recommended for heavy gage coax and
power cable in order to make loops. For
smaller cables, Ferrite core Model#31500
is recommended.
