2-7. CHANGING DIRECTION OF RADIATION (ANTENNA CURTAIN ROTATION)
The direction of radiation can be changed by rotating the antenna curtain with the TOWER maintained in its
present position. Rotation of the curtain requires a crew of six (includes a designated crew chief). Perform curtain
rotation as follows:
WARNING
DEATH ON CONTACT
Transmitter must be shut down and tagged "Out of Service" before rotating antenna
curtain. Contact with high RF voltages can be fatal, and electromagnetic radiation can
cause severe or fatal internal burns.
Antenna curtain must NOT be rotated in winds higher than 20 MPH (32 KMH). Antenna
damage and/or personnel injury could result.
NOTE
The ANTENNA GROUP contains extra ANCHORS (screw-in and pound-in) for use in
establishing a second direction of radiation (beam) to eliminate the need for removal
of existing primary anchors. The following procedures assume that these anchors are
available for use. If all anchors, including spares are in use, remove unused anchors
from their current locations for use during curtain rotation.
Shut down transmitter and tag transmitter "Out of Service".
Disconnect transmitter coaxial cable from ANTENNA COUPLER connection.
Disconnect the VERTICAL FEEDLINE and CENTER LAYOUT WIRE from ANTENNA COUPLER.
Disconnect BACK and SIDE LAYOUT WIRES at CLAMP 3 and 4 on CENTER LAYOUT WIRE.
