Sec.  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.
