Thank you for purchasing a Shakespeare antenna product. 
Customer comments are welcome. Before installing, please study the 
diagram and check parts supplied against those listed.
IMPORTANT! Please read all instructions before installing.
The Styles 4188-S and 4188-SL Rail Mounts are four-way, ratchet 
action rail mounts with handle. They are made of stainless steel, 
and mount easily on vertical, horizontal, or slanted rails. Their dual 
swivel action permits easy lowering of the antenna to clear overhead 
obstructions. The Style 4188-S accommodates 7/8” and 1” rails. Style 
4188-SL is for 1”, 1¼” or 1½” rails. Each mount has a 9/32” hole for 
cable feed-through and standard 1”-14 threads.
Tools required: Allen wrench
Installation Instructions
1.  Choose an antenna mounting location that is as high as possible, 
as free as possible from obstructions, and as far as possible from 
other antennas or strong sources of RF. Be sure the rail to which 
you are mounting is sturdy, and capable of supporting the strain 
of your antenna. You can attach the mount to a vertical, slanted, 
or horizontal rail.  Unlevel or non-perpendicular mounting can 
be accommodated through the bottom swivel. For convenience, 
orient the mount so that the handle action will control the up/down 
position of the antenna.
2.  Remove the two bolts which hold the bottom grip in place. Align 
the two parts of the mount on the rail end using the bolts supplied.
3.  The lower ratchet mechanism of the mount is controlled by a large 
screw, which is accessible when the bottom mounting plate is 
removed. To rotate the antenna around the bottom ratchet, remove 
the two bolts (and washers) and use an Allen wrench to loosen 
the mechanism for adjustment. The handle tightens only the top 
ratchet.
4.  Assemble the antenna to the Rail Mount, being careful not to 
damage the antenna’s cabling, if any.
To raise or lower the antenna, loosen the handle by lifting it away 
from the mount’s base, move the ratchet to the desired position, and 
tighten the handle.
