WARNING SUMMARY

TB 11-5820-1148-10

WARNING SUMMARY

SITE SAFETY PRECAUTIONS: HF Radio sites are potentially

dangerous areas. A number of hazards exist during the deployment,

operation, and tear down of tactical antenna systems, and it is

important that a safety program be implemented in accordance with

MIL-STD 882 and the safety section of MIL-STD-1472. The following

hazards are particularly associated with HF antennas, including the

FANLITE Antenna

Electrical Shock: Make certain that the deployment site is free of

overhead wires, which must be considered dangerous electrical shock

hazards. Ensure that no overhead wire is closer than 100 feet from the

mast.

RF Burns: Contact with the transmitting antenna can cause painful

injury from RF burns. Ensure that all power is OFF or isolated before

deployment, tear down, or during maintenance operations.

Collision: The mast, guy ropes, and antenna element wires are

deliberately toned down to make them difficult to see. There is a very

real collision risk from personnel, vehicles, and low flying aircraft. When

the tactical situation permits, ensure guy ropes and antenna elements

are clearly marked to prevent personnel injuries and equipment

damage; also ensure that the selected deployment site is well clear of

helicopter landing zones.

Radiation Hazards: At only one kilowatt, the radiation from the antenna is

not considered to be of sufficient intensity that a hazard to personnel is

likely. However, a potential hazard exists to nearby ordinance and fuel.

Generally, a transmit antenna should not be deployed within 700 feet of

explosive devices or within 170 feet of a fuel handling site.

Construction Hazards: Antenna erection requires two persons to safely

perform this task. To reduce the possibility of injury, mast and antenna

deployment should normally be conducted in daylight and during dry,

windless weather (UNDER 25 MPH, 40 KPH). The construction team

leader must emphasize the increased risks when conditions are less

than ideal. Antenna setup and tear down should not be attempted

during thunderstorms due to lightning risk. All team members should

wear hard hats/Kevlar/gloves and goggles during mast and antenna

deployment and tear down. Eye protection. Safety glasses, goggles,

OSHA approved eye wear. Keep all unnecessary personnel away from

the area while deploying or retracting the mast. Avoid placing hands

between sliding clamp assemblies or joints while raising and lowering

the mast. Failure to observe all warning may result in severe injury or

DEATH.
