Weight: (assembled)
Connector:
1) Unpack antenna and locate the U-Bolt package.
2 Insert U-Bolt into rear mount bracket. Note that the bracket is installed for horizontal
polarization. (See drawing above.) Use alternate mtg holes for vertical polarization.
3) Attach the feed line, and tape it to the mast. The connector should be sealed with
electronic grade RTV, butyl rubber, or equivalent. Don't forget to seal the area where the .141"
semi rigid coaxial cable extends into the rear of the antenna connector.
4) Straighten any mis aligned elements and tighten hardware if necessary.
5) The antenna SWR has been adjusted at the factory for less than 1.5:1. Additional
tweaking can be accomplished by adjusting the distance between the driven element and R1
and D1, or by adjusting the shape of the driven element.
6) If antennas are to be stacked, see "Instructions For Stacking Loop Yagis".
