ITS6000 HAR Antenna System
Standard on Versions 6010 & 6020

The ITS6000 Highway Advisory Radio Antenna System features the standard antenna, which produces a signal intensity of 2.0 mV/m at 1.5 km, the FCC maximum field level. The signal is typically signable at 3 to 5 miles. The antenna may be mounted atop a square or round pole of wood, metal or fiberglass. This HAR antenna system is packaged with a factory-wired groundplane, pole mounts and insulators, a cabinet-protected lightning arrestor system and ground bus for lightning dissipation and groundplane connection. Components include . . .

Antenna Mount and Insulators
A galvanized-steel mount allows the antenna to be attached to any type of pole, minimum 6" diameter or 6" square. Includes split-plastic insulator mounts and stainless-steel hardware.

Lightning Arrestor, Enclosure and Ground Bus
 Provided in a NEMA-4 cabinet, the lightning arrestor is bonded to an aluminum panel, which serves as support for lightning grounding and groundplane connection clamps.

Groundplane
A groundplane is the copper wire part of the antenna system buried beneath the antenna support. The PowerPlane® Groundplane is placed in a 6"-to-12" excavation that extends outward 10 to 20 feet (depending on frequency) in all directions from the pad or pole base; it is covered with backfill. The groundplane consists of a central ring of #4 bare copper stranded wire with 62 radials that extend outward in a circular pattern.
