Wrap the chain around the operating arm hinged to the top of the jacking
lever. Insert the pin to lock the lever in the stored position. Use Fold-Out 7 to
locate each part.
Use the strap wrench from the accessory kit to orient the mast by rotating the
lowest mast section. Aim the open side of the antenna in the assigned
direction. The open side of the antenna should be in line with the yellow
stripe on the mast section and the zero degree reference on the azimuth plate.
Note the indication on the azimuth plate opposite the mark on the launcher
base plate for reference during more precise orientation of the antenna. A
more precise orientation should be made later by maximizing the received
signal strength on the radio receiver. Lock the mast in position with the
azimuth lock turnscrew at the side of the azimuth plate.
Use Fold-Out 7 to locate each part. Check the spirit level to see that the
launcher is still level. Adjust the red-coded guy wires if necessary. Use the
turnbuckle on the snubbers for fine adjustment of the antenna mast.
The eight steps you have just read are those which must be performed to raise the antenna
system. It is important that you perform the steps in the same sequence they are listed.
