1) Unpack the antenna and locate the hardware package. Antennas are shipped in two
sections. In addition, a 71" long "sub-boom" is supplied. (See drawing above.) The boom is
broken between directors 37 & 38. Remove D38 and D39 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 D38 & D39 and retighten.
2) Attach the two 3 x 4" sub boom plates to the 1/2" boom and the attached angle
brackets with the 8-32 x 3/4" hardware provided. Install the sub boom to the two plates with
the U-bolt holes offset towards the rear (for mechanical balance). Use the 8-32 x 1 1/4"
machine screws to attach the sub boom to the two plates. Install the 2" U-bolt in the holes
provided in the sub-boom.
3) Attach the feedline and tape it to the bottom of the boom & sub-boom. The connector
should be sealed with silicone RTV or equivalent. A small downconverter may be attached to
the rear of the sub boom to minimize feedline losses. 32" of low loss coax will be adequate.
Route the IF and power cables along the sub boom and the cross boom of your installation.
4) Straighten any misaligned elements and re-tighten if necessary.
