shock protection.

2.5.3. Radio Frequency Grounding or Counterpoise

This grounding is used for protection from transmitted/induced RF signals, and possible radio frequency
interferences. It will not protect you from a possible lightning strike or currents with AC mains frequency.
These may be e.g., RF counterpoises (radials), which, in particular, could even be isolated from the ground.
When they are placed at the required height and have the proper length, they can resonate and be much
more effective for RF emission and protection than a direct connection to the ground.
However, this only applies to radio frequencies. They have no protective functions against electric shock
from currents with AC mains frequency, or lightning.

2.6. Connecting RF Cables, Additional Information

All connections between the tuner and the radio station should be executed in the sequence described
below, before the tuner is powered from the amplifier.
Before you start connecting the coaxial cable from the radio station to the tuner, ensure
that its two ends are not connected to anything and take all necessary precautions that
no one has access to them! Place warning signs at both ends reading:
a) Before doing anything else, connect the tuner's grounding terminal.
Do not proceed with the installation, unless you have connected the tuner grounding
terminal marked GROUND to the lightning protection grounding or the radio station
grounding system, according to tuner installation location, see Section
Considerations, Explicit Definitions
Before connecting any cable to the tuner, use a voltmeter to make sure there is no AC or
DC voltage above 12 V from the pin of the cable connector to the grounding terminal of
the tuner, from the ring of the cable connector to the grounding terminal of the tuner,
and between the connector pin and ring!
