NOTE: The TR-220 uses a software technique to narrow the beam width. When
testing inside of a hanger, multi-path reflections can cause erroneous TURN
indications. If unable to eliminate TURN message, remove antenna cable
connection to DIFF port. This will not affect any test results.
8. Position the antenna with an unobstructed line to the UUT antenna. Ensure that the
transmitter or receiver (RX/TX) that you are testing is significantly closer to the Test
Set than another operating RX/TX; else, an undesired reply or erroneous and
inaccurate results may occur.
