Taco Y81-A Instruction Sheet

FOR MODELS:
Y81-A, -2, -3.
Y-101-65, -4, -B, -5, -6, -C, -FM, -D,-H, -E.
Y-102B-F, -G, -120, -130, -150.
The Yagi dipoles and parasitic elements are all identified with a letter i.e. A, B, C, D and E. These markings will be
found on the crossarm indicating the location these elements are to be assembled on the crossarm (See Figure 6).
The antenna main mounting clamp holes are located in the crossarm perpendicular to the element holes. The dipole
insulators and parasitic elements mount to the same side of the crossarm.
Note: All Y-101 and Y-81 series Yagi have a two-piece crossarm. The antenna main mounting clamp is used to
assemble the two halves together and for this purpose four (4) 3/8" Dia. Bolts are supplied.
Start with the director element and the dipole elements and assemble them to their marked locations on the
crossarm as shown in Figure 1. Shims are supplied with Y-101-65, -4, -B, -5, -6, -C, -FM, -D,-H, and –E, to be
assembled with the dipole elements as shown in Figure 1. The dipoles are attached with 2 ¼ or 2 ½ (for models with
shims) inch long 1/4 inch bolts.
Next assemble the feedlines connecting the dipole elements as shown using feedline clamps and 5/8 inch long
10-32 screws (See Figure 2). Attach feedlines at dipoles to top of clamps with a centre-to-centre spacing of 3/4 inch
(See Figure 2).
