Antenna Tower

The trailer shelter combination must also have a self-supporting retractable tower system. The tower retraction must be electro-mechanically assisted. The self-supporting antenna tower must be capable of extending 50 feet. The wind loading for the antenna tower must be 90 mph for self-supported and guy supports for above 90 mph with ¼ inch nominal ice thickness. The antenna tower must be capable of accepting 4 antennas and one obstruction light. The antennas must be separated by 8’, same elevation.

The obstruction light is center mount and is NOT included on the 8 foot separation requirements. The antenna mounts must be compatible with standard aviation class omni-directional antennas, i.e. DPV-36 or D5072. The Obstruction light is LED / IR Obstruction Lights compliant with the FAA's Advisory Circular 150/5345-43J.

The following are the characteristic for the ancillary equipment to be mounting on the antenna tower:

• minimum antenna weight is 19 lbs per antenna.

• minimum antenna length is 154”

• obstruction light weighs 16 lbs

• typical RF cable will be LDF4-50A or LMR-400 o LDF4-50A - 0.15 lbs/f (riser, 8 cables) o LMR – 0.10 lbs/f (3.2 lbs from antenna mass to antenna)

RF cable management must be through the center of the antenna mounting apparatus. Cable management system must be capable of managing 16 RF cables, per manufacture recommendation, for antennas and one flexible ac power cable for the obstruction light. The obstruction light power conductor must be UV rated SOW type.
