Antenna System Planning
Before assembly, take time to review your installation plans for the antenna. Location of the antenna is very important. Surrounding objects such
as trees, power lines, buildings, and other antennas will interact with an HF Yagi. To minimize the effects of surrounding objects, mount the
antenna as high and in the clear as possible. Metallic guy wire within 30 feet of this antenna, if broken with strain insulators, will improve
performance.
YOU MUST INSURE THAT NEITHER PEOPLE OR PETS CAN COME IN CONTACT WITH YOUR ANTENNA WHILE IT IS IN
OPERATION. DEADLY VOLTAGES AND CURRENTS MAY EXIST. ALSO, SINCE THE EFFECTS OF EXPOSURE TO RF ARE NOT FULLY
UNDERSTOOD, LONG TERM EXPOSURE TO INTENSE RF FIELDS IS NOT RECOMMENDED. THERE IS A WARNING STICKER WHICH
MUST BE ATTACHED TO THE BOOM AS SHOWN IN FIGURE A
they are qualified to assist you. Make certain that everyone involved understands that you are in charge and that they must follow your instructions.
If you have any doubts at all, employ a professional antenna installation company to install your antenna.
System Grounding
Direct grounding of the antenna, mast and tower is very important. This serves as protection from lightning strikes and static buildup. A good
electrical connection should be made to one or more ground rods directly at the base of the tower or mast using at least #10 AWG ground wire
and noncorrosive hardware. For details and safety standards, consult the National Electrical Code. A coaxial lightning arrester should be used.
Cushcraft offers several different models such as the LAC series.

1-Boom Assembly
Lay out boom sections as shown in Figure 1A. Make sure tube ends
are free of debris to allow the inserts BE and BF to slide more easily.
Applying penetrating oil to the inserts will also be helpful. Secure the
BC/BD connection as shown in Figure1B. The other connections are
made using the element mounting hardware as shown in Figure 1C.
After the boom is assembled attach the remaining three element mount
brackets (Figure 1D).
