The EXA-2000 Remote Antenna is designed to enhance the radio range of Linear’s
receivers. This antenna can be connected to the “F” connector on many Linear
receivers to improve their range when they must be located in poor signal reception
locations. Usually an increase of 20-30% range can be expected. The versatile
EXA-2000 can be mounted either vertically or horizontally .

✶ NOTE: Generally, the higher the antenna is mounted above ground level,

the better the radio range will be.

The EXA-2000 provides maximum performance when mounted and installed
properly according to these instructions. Please read the entire instructio ns
before beginning any work. The EXA-2000 i s a 1/2 wave, center fed, antenna
composed of two parts: an antenna assembly with a ten-foot, 75-ohm coaxial cable
with an “F” connector and two mounting brackets. The cable connects to the “F”
connector on the receivers. If the antenna must be mounted further than ten feet
from the receiver, an additional extension cable of 15 feet may be used for a
maximum cable run of 25 feet. Because of the cable resistance, the performance
of the EXA-2000 may be degraded by using more than 25 feet of cable.

Attic Mounting.

Attach the antenna to a joist, beam or
some other object in the attic. Try to keep the antenna as far away from
large metal objects (duct work, furnace vents, etc) as possible.
Caution: In attics, or under room structures, metal foil back insulation
and drywall metalic vapor barriers will degrade radio range and
performance.
