Overview of weep hole additions
2
•Tohelp create new weep holes on JMA stadium antennas (SX-*, DX-*, and XGU-* models),
this guide was created for alterations made directly in the field.
•Because there are many potential tilt and install angles, this guide allows for on-the-spot
judgments to be made about where the ideal placement for new weep holes may be –this guide
will help avoid damage to the antenna itself while drilling new holes.
•This guide includes:
1) A guideline of key parameters for drilling new weep holes into the stadium antennas,
including widths for new holes, clearance for drill depth, etc.
2) A drawing of the front of the stadium antenna, showing what areas on the radome should be
avoided when drilling, since elements of the antenna could be damaged.
•SX antennas can either be mounted vertically or horizontally. As such, weep holes are required
to be drilled on site, prior to installation, dependent on the antenna orientation.

Key details for drilling weep holes
3
Notes
Hole diameter
Hole
should be created using single drill with a 1/8” bit.
# of weepholes
Minimum
of 4 weep holes nearest to the low point as possible
Drill depth
Drill
has to go only ¼” deep; drill a complete hole in the Radome (the Radome is only .100” thick).
Re-sealing holes
Recommended to
use outdoor Silicone to seal the existing weep holes that will not be needed.
Considerations
Hard stop
Setting
a ¼” hard stop on the drill bit is encouraged to limit risk of over-drilling.
Danger
zones
If
it is required to drill in highlighted danger zones, the maximum clearance is ¼”.
Side of
radome
There are
no danger zones if drilling from side of radome, but drilling should be limited to ¼” to reduce risk.
