Limitations of Low Power Radio
As a company, we feel strongly that the most honest representation of our information radio systems' performance is to state that, even though AM signals are delivered to virtually all homes, businesses and vehicles within the 3-5 mile radius of the antenna (25-75 square miles), reception will almost always be highest in vehicles. Why?
  1. Vehicle AM receiving antennas are exposed.

  2. Indoor AM receiving antennas are more likely shielded by the building structure and might be in close proximity to sources of AM interference, such as computers or AC power wires.

  3. Vehicle AM receivers themselves are commonly more sensitive to AM signals and commonly have better receiving antennas than AM indoor receivers.

As a percentage, there is no doubt that more vehicles have AM receivers, compared to residences and offices. 

As a result, we market all our Information Radio products for in-vehicle reception.

Information Radio Station is a generic term synonymous with Travelers Information Station (TIS), Highway Advisory Radio (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, wattmeter, 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.
