RadioSAFE System

Standard Antenna System

High Power plus High Efficiency
This high performance AM radio antenna offers communications professionals the ability to establish an AM broadcast signal capable of reaching greater distances than before possible with antennas of similar design. This high capacity, high efficiency antenna is compact and light-weight, making it easy to ship and install. It is also competitively priced.
Frequency Range Users
Different versions of the antenna's design allow it to function on any AM frequency in the 530 to 1710 kHz range. Field tests prove that this antenna is capable of handling hundreds of watts (conventional TIS antennas only handle 10 watts) and that it can produce a coverage pattern exceeding 20 miles in radius. Common users are emergency managers and associated amateur radio operators who want to reach their publics during times when power, other communications and internet services are compromised. Commercial broadcasters can also benefit by using the High Performance AM Radio Antenna to keep their AM stations on the air temporarily at low power following calamities. And amateur radio enthusiasts who want a solution for special applications that can be installed in confined spaces will benefit.
Travelers' Information Station licenses can easily upgrade to the HPR.0990 Antenna because it fits in the same 1.5” Insulator mounts that their stations’ antenna mounts currently have, though additional mounts may be required. The antenna’s efficiency will allow a 10-watt TIS signal to travel farther than with a conventional TIS antenna. A waiver is required from the FCC if the station’s field intensity would exceed 2.0 mV/m at 1.5 km (0.93 mile).

As a higher wattage antenna as part of the RadioSAFE System, an emergency Special Temporary Assignment (STA) from the FCC is required.

Engineering for the required waivers and STA’s can be supplied by Information Station Specialists.

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.
