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 ver sati le
EXA-2000 can be mounted eithe r vertically or horizont ally.
✶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 instructions
before beg inning any work. The EXA-2000 is 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.
STEP 1
Identify Parts.
Lay out and identify the parts as shown.
Check to be sure a ll items w ere includ ed in the kit.
STEP 2
Determine mounting location. Refer to the antenna
patterns sho wn to determ ing mo unting loca tion.
STEP 3
Attach mounting brackets.
Snap the mounting brackets
onto antenna as shown. Attaching the brackets in opposite directions
improves stability of the antenna mounting.
STEP 4
Wall Mounting
. Mount the EXA-2000 on the wall high
enough to achieve optimum range. Mount to wall using the two #8
screws provided.
STEP 5
Post Mounting (Vertical).
The EXA-2000 can be
moun ted vertica lly by attach ing to a p ost as sho wn.
STEP 6
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.
