HPR.0990 AM Radio High Performance Antenna
Offering more than twice the efficiency and ten times the power capability of comparable antennas, the HPR.0990 AM Radio High Performance Antenna is designed for medium power applications up to 300 watts on frequencies 1000-1710. See Norfolk, Virginia's, experience, linked right.

ANXX Standard AM Radio Antenna
This compact whip antenna is ideal for applications on any AM frequency in which up to 100 watts is required.
Antenna Support & Accessories
The antennas above can be mounted atop an 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.

Stands and masts are also available for mounting the antennas on buildings with flat roofs.
Groundplanes and Groundrods
A preconfigured groundplane may be supplied for burial or installation on the surface of the ground or a flat roof. “FlexPlane” Groundplanes are custom-cut based on the operating frequency, power and available space for installation. “Unirod” RF Groundrods can provide grounding in a smaller installation footprint, when groundplane deployment is not possible. See a summary backgrounder on this topic.
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 hundred of watts? We might be able to help you there too.
