ETS-Lindgren 3303 Monopole Antennas - Manual (Page 16)

Assembly
A TTACH C OUNTERPOISE
Do not lift the Model 3303 by the counterpoise.
The counterpoise attaches on the top of the
Model 3303 Rod Antenna base with the rod
element passing through the opening in the
counterpoise. Mounting the counterpoise
between the housing and the rod antenna
prevents the body of the antenna from
intruding into the field being measured.
1. Unfold the counterpoise and place it on top of the base.
2. Attach the counterpoise to the base using the four screws on the top of
the base.
