5. Make one coil for each source of
interference/antenna combination.
Set completed coils aside while you prepare
antenna coupling loops and antenna wires.
Make Antenna Coupling Loop
The antenna coupling loop is made using standard
2-conductor wire.
1. Begin with a piece of 2-conductor wire long
enough to reach from antenna to source of
interference.
Remember to measure installation path (not line
of sight) from antenna to source of interference.
Allow additional wire to create antenna coupling
loop and for positioning coil.
You may want to make/attach antenna coupling
loop and run wire to source of interference
before cutting it.
2. Remove 46cm (18in.) of outer sheath from one
end of wire, so that wires can be separated.
3. Strip 4cm (1.5in.) of insulation from end of each
wire.
4. Form a loop by splicing the two wires.
Antenna coupling loop is now ready to install.
Remaining wire is referred to as antenna wire in
the following steps.
Prepare Antenna for Cancellation
The noise cancellation process must be performed
on one antenna at a time. Follow these steps to
prepare the antenna.
1. Isolate antenna being cancelled. For more
information see Isolate an Antenna on page B-
6.
2. Remove antenna end caps.
3. Remove antenna cover.
Install Antenna Coupling Loop
Installing the antenna coupling loop is a critical
step in the noise reduction process. It is important
to follow the recommended guidelines for
positioning the loop.
