Antenna Tuning
July 2008 Revision 4.2 51/62
Note that the isolation adjustment process often requires repeating the procedure several times
between the top and center antennas and between the center and bottom antennas. This means
that it is normally more difficult to achieve good results of isolation between the center and bottom
antennas. Therefore, it is important to check and minimize the isolation between the center and
bottom antennas before moving to the top and center antennas. Typically, an isolation value equal
to or less than 600 mVpp should be obtained between the center and bottom antennas and also
between the top and center antennas.
Once the antennas have been correctly tuned for optimal impedance and isolation, it is best to
verify their synchronization with the mains power supply and the trigger threshold levels.
