FIGURE 7 - Northstar AN195 H-Field antenna

The length of the RG-58U coaxial cable must be a minimum of 20 feet,
but not more than 300 feet. Coil up any unused length of cable; do not
cut it to less than 20 feet! Be sure that all cable connectors are securely
fastened, and that the cable itself isn't subject to any tight bends.
Although the H-field antenna is generally less susceptible to impulse
noise than the whip antenna (see below), the H-Field antenna's location
remains critical in achieving optimum performance.
The Northstar 8410 Antenna Coupling Unit (ACU) consists of two poly-
carbonate pieces, a base and an upper unit, which is threaded to accept a
standard four-foot fiberglass whip antenna.
The actual four-foot whip antenna is NOT included
with the Northstar 8410 ACU antenna system.
The 8410 dimensions are listed below.
Height = 11 inches
Diameter = 2.6 inches
Weight = 1.5 pounds
