Shelter Security
The FCC requires that the transmitter be secure from entry or control by unauthorized
persons, and that any hazardous voltages or other dangers (including most tower bases)
be protected by locks or fences as necessary to protect personnel and prevent
unauthorized tampering or operation. Security of the building further implies that it be
secure from wildlife. Use sturdy construction materials, including sheet metal if
necessary. Holes around conduit, cable, and other similar entry points should be stuffed
with steel wool and caulked to prevent entry of wildlife. Other features of security for your
shelter may include its location with respect to the prevailing wind conditions. Location
leeward of some natural topographical feature will prevent wind damage and snowdrifts.
Check the soil runoff conditions that may slow or hasten wind or water erosion and other
concerns that may be unique to your location.
