Omni-directional Outdoor Scanner Antenna
with Matching Transformer and
50’ of RG-6 Coaxial Cable, with F-to-BNC adapter

BEFORE YOU BEGIN

Y our antenna has elements which are resonant in the 30-54 MHz,
108-174 MHz, 450-470 MHz, 470-512 MHz, and 800-912 MHz
bands. They work together to give you frequency coverage from
30 MHz to 1300 MHz. Before you begin assembly , read this manual
and the Consumer Product Safety Commission information. For
your safety and convenience, plan each step of the installation
and purchase the necessary hardware in advance. The order in
which you perform the steps and the hardware required depends
on the mounting and connection methods you choose. Your an­tenna comes complete with a matching transformer, 50 feet of
RG-6 coaxial cable with a F-to-BNC adapter.

We recommend two people assemble the entire antenna on the
ground, then mount the assembled antenna on the mast. The
following steps are required to assemble your antenna.

2. Press the supplied large end plugs into the main boom.

3. Hold the center and front main boom elements near the pivot
points and unfold them until they snap into the locking plas­tic suppport insulators. Position the legs on the smaller front
elements outward, so they line up with the elements under
them. Pull the swivel bracket elements outward until they
snap into the swivel brackets’ tabs.

Warning: When you install your antenna, use extreme caution.
If the antenna starts to fall, let it go! It could contact overhead
power lines. If the antenna touches the power line, contact with
the antenna, mast, cable, or guy wires can cause electrocution
and death. Call the power company to remove the antenna. Do

not attempt to remove it yourself.

CONNECTING LEAD-IN CABLE TO THE ANTENNA

Follow these steps to connect the RG-6 coaxial lead-in cable to
the antenna.

1. Attach one of the coaxial cable’s F-connector ends to the
supplied matching transformer. Use plastic tape to weath­erproof the connection.

2. Thread the transformer’s spade terminal ends through
either slot of the antenna’s strain relief tab, with the spade
terminal ends pointing towards the antenna’s lead-in termi­nals marked CONNECT LEAD-IN HERE. Use the supplied
washers and wing nuts to secure the transformer’s spade
terminal ends to the antennas lead-in terminals.

ATTACHING TO THE MAST

Slide the antenna’s mast clamp assembly over the end of the

mast. Then tighten the mast clamp assembly’s lock nuts to hold
the antenna in place. Take care not to overtighten the nuts.

Notes:

• Use a plastic tape to secure the cable to the mast at about

3 foot intervals.

• Use coaxial nail clips every few feet to secure the cable to

walls.

• Use a 75-ohm grounding block where the cable enters the

house. Read the Consumer Product Safety Commission in­formation Sheet for grounding instructions.

• Use a wall-through tube to neatly route the cable through

walls.

3. Tape the transformer and coaxial cable to the antenna
boom using plastic tape.

ATTACHING TO YOUR SCANNER

Attach the F-to-BNC adapter to the other F-connector end of

the coaxial cable, then attach the adapter to the scanner’s
antenna input.
