Free-Standing AM Radio Antenna System with Tower

 Vertical Profile Antenna Support and Grounding System

Our standard AM radio antenna produces a signal intensity of 2.0 mV/m at 1.5 km, the FCC maximum field level. That signal is typically strong enough to erect signs for alerting listeners at 3 to 5 miles. Its frequency range is 530-1710 kHz.

The antenna may be mounted atop a square or round pole of wood, metal or fiberglass.

Required accessories includes insulators, mounts, support poles or masts, lightning arrestors, groundplanes or groundrods.

Information Radio Stations is a generic term synonymous with Travelers Information Stations (TIS), Highway Advisory Radio Stations (HAR) / Highway Information Systems & Low Power Radio Stations (LPR). Operation of the stations is governed by FCC Part 90.242 Rules. A FCC license is required. Information Radio Stations may be fixed or portable. Subcomponents may include transmitter, antenna and ground system, digital voice player, wateter, cabinet with conventional or Corbin locks, lightning arrestors for RF, power and telephone lines, coaxial cable. Most stations employ black maximized antennas to discourage ice accumulation and security measures to prevent unauthorized program access. Options include synchronization, battery backup, solar power, remote programming by local, network or telco, multi-station audio distribution via RF or LAN / WAN or wireless network.
