FCC Form 1023 FEDERAL COMMUNICATIONS COMMISSION
August 1968 Washington; D. C. 20554

REQUIREMENTS FOR CONSTRUCTION OF ANTENNA TOWERS
For Use by Stations Authorized At Temporary Locations

Antenna structures for land, base and fixed stations authorized in the Safety and Special Radio Services for opera­
tion at temporary unspecified locations may be erected without specific prior approval of the Commission where
such antenna structures do not exceed a height of 200 feet above ground level; provided that the over-all height of
such antennas more than 20 feet above ground, including their supporting structures (whether natural formations or
man-made), do not exceed a slope of 1 foot above the established airport elevation for each 100 feet of distance or
fraction thereof from the nearest boundary of such airport.

Any antenna to be erected in excess of the foregoing limitations requires prior Commission approval. Licensees
seeking such approval should file application for modification of license accompanied by a completed FCC Form
714. (When using FCC Form 400 dated November 1967, or later, FCC Form 714 is not required.)

In addition, notification to the Federal Aviation Administration is required whenever the antenna will exceed 200
feet above the ground and whenever notification is otherwise required by Section 17.7 of the Commission’s Rules.
Such notification should be given by filing Form FAA-117, in duplicate, with the nearest office of the Federal
Aviation Administration.
