If you plan to use your own coaxial cable instead of the provided cable, you must use
cable and connectors rated at 50 ohms. Although cable used for cable TV installations
loo s similar to this cable, it won’t wor with your Listen system.
If you need to run cable over a greater length than 50 feet for 216 MHz applications or
greater than 100 feet for 72 MHz applications, we recommend that you use RG-8 cable
rather than RG-58. It is a lower loss cable, meaning that more of your signal will reach
the antenna.
Long cable runs can result in signal degradation due to “loss” characteristics of the
cable. At 72 MHz, there is a loss of 2dB per 100 feet of cable and at 216 MHz, there is a
loss of 5 dB per 100 feet of cable. (A 3dB loss means half of your power has been lost.)
However, it is better to suffer coaxial power loss than to try to shoot your signal throughit is better to suffer coaxial power loss than to try to shoot your signal through

The antenna’s pattern is hemispherical, meaning that it has an “active” side and a
ground side. The active side directs the signal toward the receivers, so it is
essential that the active side be oriented toward the area where the receivers will
be used. The Antenna Module’s ground side has the word “GROUND” molded
into the plastic.
See Diagram A. If it is necessary to locate an antenna low on a wall, the ground
side should face down. If you are mounting a monopole antenna in a ceiling or
high on a wall, the ground side should face UP. It may be necessary to move the
ground side of the antenna mount around in order to accomplish this.
To move the ground side of the module, simply remove the four nuts, reverse the
module so that the ground side is facing the bracket, then re-attach the nuts. Be
careful to not detach any wires if the module opens while it is not secured to the
bracket.

Selecting an Antenna Locationocation

The location and configuration of your antenna mount will determine the quality
of your signal; therefore, there are some important factors to consider.
ºWhere will the receivers be located? Ideally, the antenna will be centrally
positioned above that area.
ºWhere will the transmitter or stationary receiver / power amplifier be located?
We recommend that it be located no more than 25 feet (7.6 meters) from the
antenna.
ºAre there any metal obstructions in the area? Ideally, there will be no metal
between the antenna and the receivers. Also, try to avoid mounting the
antenna in a location where nearby metal would be in parallel with the an-
tenna -- this degrades the signal.
ºWill the antenna be mounted outdoors? Antennas work well outdoors, but if
possible, try to place the antenna where it will not receive too much exposure
to moisture or dirt. Covering exposed connections with petroleum jelly or
silicone gel will extend the life of the antenna.

Several types of antennas are included in this kit. You will only use one of them.
How do you select the best antenna?
ºFirst, what is your operating frequency -- 72 MHz or 216 MHz? This eliminates
half of the antennas since you can only use an antenna that will work for your
frequency range. Remember, the LONGER antennas work on the lower
frequency of 72 MHz and the SHORTER antennas work at 216 MHz.
ºNext, do you have any space restrictions? The rigid dipole antenna (the one
with the two extendable arms) provides the best signal, but only if you can
fully extend the sections of the antenna. If you can’t fully extend the rigid
dipole, you will need to go with either the flexible dipole or the monopole
antenna. We recommend using a dipole antenna whenever possible.
ºIf you need to mount your antenna on top of an equipment rack, you will need
to use the monopole antenna.
ºFor mounting in a ceiling or in a wall, or taking up the least amount of space
along an outside edge of a wall, the flexible dipole antenna is a good choice.
Remember, though, that you need to extend the sections of this “floppy”
antenna as far apart from each other as possible.

Dipole Antenna Mounting Options
Mount to an Electrical Box in a Wall
See Diagram B at right
The antenna may be mounted to a single or
dual gang duplex box, or to a square or
hexagonal junction box.
Attach the kit’s Mounting Plate to the electri-
cal box (see photo, right). The cover plate
has a number of holes and slots to
accomodate a wide variety of electrical boxes.
Next, secure the Mounting Bracket to the
plate and connect your antenna as noted in
the following pages.
Mount Directly to a Wall
See Diagram C at right
We recommend using the Mounting Plate to
make for a sturdier installation, however, it is
not necessary to do so. If you use the
Mounting Plate, you will need to provide two
shallow clearance gaps in the wall to allow
for the two protrusions in the Mounting Plate.
Use appropriate anchors to secure the Mount-
ing Plate to the wall (hollow wall anchors are
provided in this kit), then secure the Mount-
ing Bracket to the plate. If you are not using
the Mounting Plate, use appropriate wall an-
chors to mount the Mounting Bracket directly
to the wall.

Mounting Inside a Wall or Ceiling
See Diagrams D and E
The antenna may be hidden inside a wall or ceiling IMPORTANT: Do not install
the antenna inside a metal wall or ceiling, as this would obstruct the signal
You will use a flexible dipole (the floppy wires) in this configuration Select the
correct wires for your configuration (72 MHz or 216 MHz) Connect one
antenna wire to the ground side of the Antenna Module using one of the Hex
Kep nuts provided Connect the other wire to the active side using the other
Hex Kep nut, as noted in Diagram D below If you are using a Mounting Bracket,
you will need to install the provided fiber washer between the antenna and
mounting bracket
Secure the mounting bracket to a beam, making sure the active (non grounded)
side of the antenna is directed toward the area where the receivers will be
located (see Diagram E below) Then, secure the ends of the antenna to beams
using wood screws or the provided sheet metal screws Try to make the wires
as straight as possible, and make sure they extend in opposite directions

Mounting to a Mast or Conduit
The antenna may be mounted to a mast,
pole or section of vertical conduit A mast
made of non-conductive material works
best; however, if you must use a metal mast,
be sure to orient the antenna mount so the
mast is not between the antenna and the
designated receiving area
The Mounting Plate is not required, but will
provide a stronger mount for the antenna
Secure two commercially available conduit
clamps (not included in this kit) to the mast,
then attach the Mounting Plate to the clamps
and connect the Mounting Bracket to the
Mounting Plate, as shown in the photo at
right

Insta ation of a dipo e antenna on a vertica mast with the
Mounting P ate. Note that the antenna is insta ed at the TOP
of the mast.
IMPORTANT (see Diagram F at left): When installing an
antenna on a metal mast, make sure the mast does not extend
above the antenna module If you are mounting the antenna in
a high location (such as a stadium), the active element should
be at the bottom If mounted low, the active element will be at
the top of the installation Make sure the antenna is mounted
in such a way that the mast will not interfere with the signal

Connecting the Dipole Antenna
You have two choices of antenna with
the dipole option: the rigid dipole,
which has the two extendable arms,
or the flexible dipole, which has the
“floppy” wires with securing rings at
the ends Rigid dipole pieces screw
onto the connectors at the top and
bottom of the Antenna Module Flex-
ible dipole wires are secured using
Hex Kep nuts and a fiber washer as
indicated on page 9
If you don’t have enough room to fully
extend the ground arm of a rigid
dipole, you can use half of a rigid di-
pole for the active side and half of a
flexible dipole for the ground side
Although the dipole works best when
the wires are fully extended straight,
satisfactory operation can still be ob-
tained when you slightly bend the
ground wire (not the active one!) to fit
around a ceiling or floor corner
Connect the coaxial cable (either the
cable provided in the kit or your own)
to the Antenna Module’s BNC connec-
tor Connect the other end to the
LT-800 transmitter or the LR-100
Receiver / Power Amplifier, depending
on which device you are using
If you supply your own cable, you
MUST use 50 Ohm coaxial cable and
connectors Do not use cable made
for cable TV installations; it is rated
at 75 Ohms and will not work in this
application
Rigid dipole sections screw onto the opposite sides o the
antenna module, and are then ully extended.
Using hal o a lexible dipole or grounding a rigid dipole. This
is a good choice when you don’t have room to ully extend the
ground side o the dipole.

Monopole Antenna Mounting Options
A monopole (single element) antenna may
be mounted to a grounded light box or junc-
tion box in a ceiling or floor using the Mount-
ing Plate and Mounting Bracket
BEFORE STARTING, reverse the Antenna
Module on the Mounting Bracket, then install
the Hex Kep nut on the ground post (see
Diagram G at right) The combination of the
Mounting Bracket, nut and your grounded
electrical box provides the required ground
for the antenna
If you do not have access to a grounded box,
you will need to attach a flexible antenna el-
ement to the ground side of the Antenna
Module (see Diagram I) Be sure to use the
correct length element (longer wire for 72
MHz, shorter one for 216 MHz) Connect the
wire underneath the shorting nut and run it
up into the ceiling

I’m not hearing anything in my receiver.
1. Make sure the receiver’s batteries aren’t dead, that it is turned on, set to
the right channel, and the volume has been turned up.
2. Make sure your transmitter or stationary receiver has been powered up
and set to the right channel, and the desired audio has been applied.
3. Make sure the coaxial cable has been tightly attached to both the antenna
and the transmitter / stationary receiver.
4. Make sure you have used 50 ohm coaxial cable.
5. Make sure the antenna element(s) has been securely attached to the
Antenna Module.
I’m getting a signal, but it isn’t very strong.
1. Make sure you are using the correct antenna element(s) for your operating
band (72 MHz or 216 MHz). Antennas for 72 MHz are longer than those
used for 216 MHz.
2. If you are using a dipole antenna, make sure both elements are securely
attached to the Antenna Module and that they have been fully extended in
opposite directions.
3. If you are using a monopole antenna, make sure it has been grounded with
either the grounding plate / grounding base or a flexible antenna attached
to the grounding post on the Antenna Module.
4. Make sure the active element of the antenna is directed toward the area
where the receivers are being used and that the ground side is directed
AWAY from the receive area.
5. Make sure the antenna has been placed in an area free of metal obstruc-
tions.
6. Check the operating power of your transmitter - there are three settings,
1/4, 1/2 and full power. Increase the power if it’s low.
