Yagi Antenna Installation
To prevent electrocution or severe personal injury, install antenna away from
prower lines and install with proper grounding.
Yagi Antenna Pre-Assembly
See Figure 14.
To per-assemble the antenna, do the following:
1. Unpack the antenna and locate the following parts:
• Boom (1-14 inches for 5 element model, 7/8 inch diameter for 3 element
model)
• 3/8 diameter elements (y---3 = 3 elements, y----5 = 5 elements)
• Gamma match parts bag
• Mounting bracket parts bag
2. Find the proper element dimension chart for your antenna, within the antenna
instructions, and trim each element according to your operating frequency.
Use care to trim equal lengths from each end of each element ensuring that the
mounting hole is at the center.
NOTE A
: Proper trimming and adjustment is critical to the Voltage Standing
Wave Ratio (VSWR). (High reflected power levels decreases forward power. The
life of the radio and transmit capabilities is dependent upon the VSWR being low
as possible).
NOTE B
: If you are using two frequencies, trim the antenna to the transmit
frequency of the unit where the antenna is mounted.
3. Insert the elements into their respective locations through the boom, starting with
R1 (the reflective element) in the hole closest to the mounting holes. Then insert
Dr, D1 etc. in that order.
NOTE A
: Shortest element is furthest away from the mount and increases in size
as it gets closer to the mount.
NOTE B
: Be very careful to line up the holes and not cross thread when securing
the elements in the next step. The bolts must tighten all the way down upon the
lock washers.
4. Secure the elements with the stainless steel 10-32 hex bolts and #10 lockwashers
provided.
