§ 95.2141   LPRS antenna height and directivity requirements.

   LPRS operators must ensure that their stations satisfy the antenna
   requirements in this section.

   (a) For LPRS units where the antenna is an integral part of the unit,
   and for LPRS stations operating entirely within an enclosed structure,
   e.g., a building, there is no limit on antenna height.

   (b) For all other LPRS units, the tip of the antenna must not exceed
   30.5 meters (100 feet) above ground level. If harmful interference
   occurs, the FCC may require that the LPRS station antenna height be
   reduced.

   (c) Directional transmit antennas must be used for LPRS stations used
   with AMTS.

   (d) LPRS antennas must also meet the requirements in § 95.317 regarding
   menaces to air navigation. See 47 CFR 95.317 and consult part 17 of the
   FCC's Rules for more information (47 CFR part 17).
