Dipole Antenna Mounting Options

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. 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.

Rigid dipole sections screw onto the opposite sides of the antenna module, and are then fully extended.

Setup Instructions

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.
