Page 15: Assembly, Mounting, And Operation
Antennas are precision measurement devices. Handle your antenna with care. Do not cross thread any connections or permanent damage to the antenna could occur. The 1/4–20 mount on the bottom of the Model 3303 is not a ground location. Assembly, Mounting, and Operation... -
Page 16: Assembly
Assembly TTACH 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. -
