VP9000 Vertical Profile Antenna System (for fixed-location operation)
HearMoreInfo/StreamCast Service (for streaming broadcasts to smartphones, tablets, laptops & PCs)
Signal Measurement Radio Receiver (to ensure FCC signal compliance long term)
2X Signal Booster
  • 16' black, anodized pole extension to existing antenna system offers up to double the efficiency/range of the station's antenna and allows the transmitter to run at less wattage or the signal to have twice the signal intensity at a given distance.
  • Functions with upper-band (typ:1610-1700) antennas only and is recommended for federal government agencies that do not have a signal intensity limitation; also for any operator in a challenging environment that requires maximum signal intensity to cut through woods, buildings and obstructions. (Note: local government licensees must seek a waiver of the FCC rules to allow a signal intensity above the standard 2.0 mV/m limitation.)
Antenna Height Extender: 10' black, anodized pole extension to existing antenna system increases signal strength 70%, useful for areas challenged by terrain, interference or obstructions.

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.
