Antenna Installation
If any problems appear during this process, please call Shively Labs and dis-
cuss them with the installation designer.
Installing the
transformer
One of the unique features of Shively Labs antenna systems is the adjustable
impedance-matching transformer provided with the antenna. It allows the
installer to compensate for changes in the input impedance caused by the
installation (tower, conduit, ladder, etc.).
NOTE
The transformer may be oriented in whichever direction you wish (see
Figure 10
). Make it easy for yourself to reach for adjustment at startup.
Install the transformer between your transmission line and the feedline. The
male end (with the inner conductor connector in place) always goes at the
top. Transformer mounts are generally similar to feedline mounts and should
be installed in the same manner.

Installing parasitic
elements
(if applicable)
If your antenna includes parasitic elements, these are shown on your installa-
tion drawing. Install them exactly as shown on the installation drawing.
CAUTION
Be sure to follow all dimensions and angles shown on the installation
drawing, or your antenna will not perform as expected.
Each parasitic element clamps directly onto the feedline with clamps.
On the mounting bracket for each horizontal parasitic element, there is a small
spot of weld which you must line up with the centerline of the radiator. This
alignment is critical to the proper directionality of the antenna.
