Setup Instructions
Dipole Antenna Mounting Options
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.
Flexible dipole wires are secured using Hex
Kep nuts and a fiber washer as indicated
on page 7.
If you don’t have enough room to fully
extend the ground arm of a rigid dipole,
you can use half of a rigid dipole 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 obtained 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 connector.
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.
Connecting the Dipole Antenna
Rigid dipole sections screw onto the opposite sides
of the antenna module, and are then fully extended.
Using half of a flexible dipole for grounding a rigid
dipole. This is a good choice when you don’t have
room to fully extend the ground side of the dipole.
