8.2 Radio interference
Gallagher energizers comply with usual
Telecom and International standards and
safety regulations. However, problems can
arise for a number of reasons and can be
difficult to eliminate in areas with poor radio
reception.
To avoid radio interference:
• The energizer earth must be highly
conductive (refer to
“4.3.1 Installing the
Earthing (Grounding) System”
)
• The energizer must be well away from
any mains power supply earth and neither
should be connected to water pipes.
• Do not allow an energizer earth wire
to touch a building which can act as a
broadcast aerial. Use Leadout Cable G627
to insulate the earth wire.
• Earth the offending radio and improve its
aerial. Try to keep both as far away from
the energizer and fence lines as possible.
• The mains power supply earth must be in
good condition.
• The mains power supply plugs and sockets
for the energizer and radio must be in
good condition with no loose connection.
• Spray grass along fence lines closest to the
radio with defoliant spray.
8.3 Telephone interference
To avoid telephone interference:
• Do not have electric fence wires running
for any distance parallel to telephone
wires or power lines. This particularly
applies if the electric fence wire is carrying
high current, such as a leadout wire to a
large fencing system.
• All joins should be “figure eight” or
“reef knots” and all other connections
should be joint clamped securely so there
is no sparking. Re-tighten clamps every
summer.
• Ensure cut out switches are in good
condition with no loose connections.
• Maintain your insulators in good
condition. Poor quality insulators can
cause problems that are difficult to trace.
Sparking inside these also causes radio
interference.
• Under gateways, use Leadout Cable
(G6270 or G6272) threaded through
plastic piping for physical protection,
avoiding sharp objects. It must be flexible
to allow for strainer post movement.
• To find leaks, shorts, faulty joins, broken
wires, and faulty insulators, walk the
fence lines with a transistor radio tuned
off the station and on high volume. It will
click when a fault is close.
• If there is still a problem:
Operate the energizer without the earth
or fence connected. If the interference
stops then the fault is in the fence line or
earth. If it is still there then the fault is in
the energizer or in the mains (110V/230V)
power supply connections.
