Transmitters
The TR.6000 AM Radio Transmitter Model 15.73 is a tried and true workhorse solution for 0-10 watt AM operation. Employed for emergency and temporary applications, this model requires only 1RU in height. It delivers a high quality AM signal on any AM frequency (10 kHz or 9 kHz spacing). Its input accepts balanced 600-ohm audio and the RF output connects to standard 50-ohm cable.

Need a transmitter that's capable of hundreds watts? We might be able to help you there too.
Antennas
HPR.0990 Antenna
Offering more than twice the efficiency and power capability of comparable antennas, the HPR.0990 High Performance AM Radio Antenna is designed for medium power applications of 200-300 watts depending on frequency. See the HPR.0990 High Performance AM Radio Antenna webpage. See also Norfolk, Virginia's, experience, linked right, and the March 31, 2021, Radio World letter from Paul Dobosz:  "ISS antenna is an option in an AM pinch; It fills a need for cost-effective, compact AM and TIS antenna."

AN2X Antenna
Next in line is the AN2X Antenna, which has a much longer basepipe than the standard ANXX Antenna (described immediately below), and so offers higher efficiency. See technical specifications here.

ANXX Antenna
The ANXX Standard AM Radio Antenna is a compact whip antenna that is ideal for applications on any AM frequency in which up to 100 watts is required. View specifications.
Antenna Support & Accessories
The antennas are commonly installed on a flat building roof or on the ground. They can be mounted atop a new or existing antenna support structure (pole, tower or mast) or the VP.9000 Vertical Profile Antenna Support and Grounding System, which is manufactured specifically to support them. The VP.9000 System accommodates antenna mounts and stand-offs, a groundplane connection, an integral lightning arrestor and other required subcomponents.
Groundplanes
A preconfigured groundplane may be supplied for burial or installation on the surface of the ground or a flat building roof. “PowerPlane” Preassembled Groundplanes are custom-cut based on the operating frequency, power and available space for installation. See a summary backgrounder on this topic.
Rent a Radio Station
A complete, portable 10-watt radio station on wheels can be shipped to your door, set up for your broadcast frequency. EventCAST Stations may be set up to admit your programming, or provide the means to repeat a recorded program that you provide. We can even record and supply programming. Just say “go.”
(*) Preowned / certified components are often available upon inquiry. Use of these products by licensed broadcasters may be covered by adherence to FCC Part 73 Rules.

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
