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 "sub-boom" is supplied (see drawing above.) The boom is broken
between directors 55&56. Remove D56, D57 and D58 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 D56,57& D58 Note that D56-58 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.
