DRIVEN ELEMENT ASSEMBLY - cont'd
1.
Select one of the folded dipoles and insert the reinforcing inserts into the tubing
ends, aligning the holes.
2.
Mount the dipole element to the insulator using the 8-32 x 1" screws, nuts, and
lock washers. See the sketch above for the correct hardware arrangement. Repeat
Steps 1 and 2 for other dipole assembly.
3.
(Refer to assembly pictorial) Mount the vertical dipole first, element to the front,
insulator mounting block to the rear Orient insulator on same side as 1" clip. Insert
8-32 x 3" mounting screw from the opposite side of the boom. Place a #8 flat washer,
lock washer and nut on the screw and hand-tighten.
Mount
the
horizontal
dipole in the same way, with the insulator oriented on the
underside of boom. Add an additional lock washer and nut to the mounting screw to
provide an even platform for mounting the PC board.
4.
Place the PC board onto the horizontal dipole studs first, then add the coax balun
leads (lugs on feedpoints, strap on mounting stud). Secure with three sets of 8-32 flat
washers, lock washers and nuts.
5.
Place the SO-239 case into the clip, connector facing rear. Place the other coax
balun on the vertical dipole studs, then add the coax lead from the SO-239 case. Place
braid strap on the mounting stud. For unkeyed RHC (right-hand circularity) connect the
center lead to the UPPER feedpoint stud. for unkeyed LHC (left-hand) connect the
center lead to the LOWER feedpoint stud. Secure coax leads with harness ties as
shown in Assembly Pictorial.
