BEFORE INSTALLING YOUR NEW ANTENNA, PLEASE BE SURE
1) Unpack the antenna and locate the hardware package. Antennas are shipped in two
sections. In addition, a 48" long "sub-boom" is supplied (see drawing above.) The boom is
broken between directors 37 & 38. Remove D38, D39 and D40 from the front boom section
and slide the two boom pieces together. Use the alignment marks on the boom to correctly
connect the boom pieces. Align the elements. Replace D3839 & D40 Note that D38-40 are all
similar in size. Tighten the elements on the boom.
2) Straighten any misaligned elements and re-tighten if necessary.
DE or D1, as these have been factory set for minimum SWR.
