Please Note: A qualified structural engineer
should be consulted prior to mounting an
antenna on a tower or support structure.

TACO RUGGEDIZED YAGI ANTENNA
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).

SAFETY PRECAUTIONS
1. To protect your antenna and equipment from lightning damage, you should use a lightning arrestor. Attach the
lightning arrestor to the downlead at the point where it enters the building. Drive a ground rod at least 4 feet
into the ground. Use ground wire to connect the antenna mast and the lightning arrestor to the ground rod.
2. Keep antenna and downlead a safe distance from any power lines.

FIGURE 6
For stacking antennas in an array on a limited frame, the antenna support braces can be inverted or installed going up
at an angle instead of going down at an angle. CAUTION must be used to insure that the
antenna radiators be oriented in spaces identical (in phase condition), therefore to eliminate any interference between brace and antenna, a 2 in. spacer (not supplied) must be installed between antenna
crossarm and brace bars as shown in Figure 7.
