1. If the antenna has a 2- or 3-section crossarm boom, assemble the
sections witln screws and wing nuts. (See Fig. 1) For 3-section antennas,
assemble with the short elements to the front of antenna and the Iong
elements to the rear of antenna. When assembling, push the front or rear
sections into the center section with the slot in the front or rear sections
pushed against the rivet, holding the insulator to the center section.
This will Iine up the holes for the screw and wing nut.
2. Open alI elements on the antenna. NOTE: The elements on this antenna
are tightly riveted. To avoid bending the elements while opening, grip the
elements near the rivets. (See Figs. 2 & 3)
3. Swing phasing rods (riveted to center section) into position on the front
section and secure with wing nuts. (See Fig. 4) NOTE: Do not attach
transmission wire or balun to these points. Transmission wire or balun
are attached to the bottom terminals of the folded UHF dipole as shown
in Step 5.
4. Thread standout into hole provided in Iower refl ector crossarm. (See Fig. 5)
5. Attach transmission wire (or balun, if coax installation) to tap-off terminals
at the bottom of the UHF dipole, as shown in Fig. 6 (or 6A if a straight UHF
screw dipole).
6. Fasten antenna to mast using U-bolt assembly as shown in Figs, 7 & 8.
7. If the antenna has boom braces, secure them to the mast below the
antenna as shown in Fig. 9. (Make sure the main crossarm is straight
when tightening U-bolt nuts securing the boom braces.)
