§ 95.208   (R/C Rule 8) How high may I put my antenna?

   (a) Antenna means the radiating system (for transmitting, receiving or
   both) and the structure holding it up (tower, pole or mast). It also
   means everything else attached to the radiating system and the
   structure.

   (b) If your antenna is mounted on a hand-held portable unit, none of
   the following limitations apply.

   (c) If your antenna is installed at a fixed location, it (whether
   receiving, transmitting or both) must comply with either one of the
   following:

   (1) The highest point must not be more than 6.10 meters (20 feet)
   higher than the highest point of the building or tree on which it is
   mounted; or

   (2) The highest point must not be more than 18.3 meters (60 feet) above
   the ground.

   (d) If your R/C station is located near an airport, and if you antenna
   structure is more than 6.1 meters (20 feet) high, your may have to obey
   additional restrictions. The highest point of your antenna must not
   exceed one meter above the airport elevation for every hundred meters
   of distance from the nearest point of the nearest airport runway.
   Differences in ground elevation between your antenna and the airport
   runway may complicate this formula. If your R/C station is near an
   airport, you may contact the nearest FCC field office for a worksheet
   to help you figure the maximum allowable height of your antenna.
   Consult part 17 of the FCC's Rules for more information.

   Warning: Installation and removal of R/C station antennas near
   powerlines is dangerous. For your safety, follow the installation
   directions included with your antenna.
