SAFETY PRECAUTIONS
1. To protect your antenna and equipment from lightning damage, you should use a lightning arrestor. Attach the
lightning arrestor to the downlead at the point where it enters the building. Drive a ground rod at least 4 feet
into the ground. Use ground wire to connect the antenna mast and the lightning arrestor to the ground rod.
2. Keep antenna and downlead a safe distance from any power lines.
The antenna Braces are assembled to the crossarm at their marked holes 1 or 2 (perpendicular to the
element holes) with 1/4” x 2 1/4” Hex Head Bolts, Reinforcing Clip, Washer, Lockwasher and Hex
Nut. Opposite ends are assembled to the channel and 3/8” U-Bolt, Washer, Lockwasher and Hex Nut
