ASSEMBLY INSTRUCTIONS
1)
Unpack the antenna and locate the hardware package. Some antennas are shipped in
two sections, in which case the boom is broken between directors 37 & 38. Remove D37 and
D38 from the rear boom section and slide the two boom pieces together. Align the elements.
Replace D37 & D38 and retighten.
2)
Straighten any misaligned elements and tighten hardware if necessary.
But do not touch
R1, DE or D1, as these have been factory set for minimum SWR.
3)
Install the U-bolt into the boom to mast bracket so that the mast comes up directly
under the boom.
Note that the bracket can be installed for either vertical or horizontal polarization.
