INSTALLATION OVERVIEW
INSTALLATION TIPS TO AVOID INTERFERENCE ISSUES
Since electromagnetic interference (EMI) issues with tower lighting systems installed on broadcast structures are
hard to pinpoint and diagnose, it is best to prevent issues in advance by following good installation practices.
These include shielding, grounding, and filtering as outlined below.
SHIELDING AND GROUNDING
The goal of shielding and grounding is to block EMI by surrounding all conductors and electronics of the lighting
system with a continuous metal shield, which is grounded to the tower structure. This shield must have no gaps
since RF Energy can pass through very tiny openings in metal enclosures or conduit.
Ensure that all enclosures, junction boxes, and conduit are mounted on the tower structure with a tight
metal-to-metal mounting (not through paint or rust).
Verify that all enclosure and junction box doors and covers fit tightly and latch securely.
Plug all unused enclosure holes with metal fittings or plugs.
Run all power and communication cables and conductors within metal conduit or metallic flex.
Ensure that all conduit and flex are in good condition so that metal completely surrounds all conductors
including at junction of conduit/flex fittings and enclosure.
Ensure that all conduit and flex fittings are correct type and size, and properly installed so that they make
a tight metal to metal connection at each enclosure entry.
Consider grounding the conduit at the base of the tower directly to the ground ring using #2 solid.
