The better-known tower manufacturers offer complete technical and safety
documentation with their towers. Be sure that you have this information as it
regards wind loading, guying, etc. The best-designed antenna system will
function poorly if shortcuts and compromises are used during installation. Follow
the manufacturer’s instructions exactly, along with any engineering data prepared
for the site. Be absolutely safe and certain about this aspect as human lives may
be at stake.
Shelter Security
The FCC requires that the equipment 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. Locations 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.
Heating and Cooling Requirements
The environment’s temperature will contribute greatly to the length of the power
amplifier’s or transmitter’s life. Technalogix recommends that the building’s
filtered air intake must have capacity for all air-flow in the building plus an
additional 20%. Keep the intake below the roofline to avoid intake of solar heated
air. Please ensure that the intake and exhaust areas are on the same side of the
building to avoid pressure differentials during windy conditions. Also, do not
position intake near exhaust’s preheated air. If air conditioning is required to cool
the shelter, discuss the situation with a qualified HVAC technician. Under
average conditions, 12,000 BTUs will cool approximately 500 square feet to a
comfortable level.
The fans internal to the enclosures help cool the components. The specific fan
voltages and part numbers are listed in the Block Diagram included with the
Quickstart package.
