Antenna
System |
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. |
