ASSEMBLY AND INSTALLATION PROCEDURE
IF YOU DID
NOT
PURCHASE OR DO NOT WISH TO INSTALL THE 20 METER
ELEMENT, SKIP SECTIONS 13 THROUGH 16, 22 AND 23.
WARNING!
You can be killed if the antenna, feedline, or the equipment used to
install the antenna accidentally contacts any utility lines. Never install an antenna
near power lines!
1.
Be especially careful while moving or installing this antenna. This antenna is bulky
enough to cause a loss of balance if handled by an inexperienced person, or if a
capacitance spoke accidentally becomes snagged on a gutter, a tree limb, or any
other object.
2.
Mount the antenna in a location completely out of reach, or protect it with a non-
cunductive fence. The ends of the capacitance spokes and other parts of the antenna
can cause eye injury, serious RF burns, or both.
3.
Be sure the mast is sturdy enough to support more than 20 pounds of weight and a
wind load of approximately 3 square feet.
NOTE: WEAR SAFETY GLASSES WHENEVER
WORKING ON OR NEAR THIS ANTENNA.
During assembly please refer to the figures listed in the
following steps as well as the figures on the inside front cover.
