Antennacraft Antenna ST2 manual

							BEFORE YOU BEGIN
Your 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 an-
tenna 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.
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.

points and unfold them until they snap into the locking plas-
tic 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.

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 in-
formation Sheet for grounding instructions.
•Use a wall-through tube to neatly route the cable through
walls.
CONNECTING LEAD-IN CABLE TO THE ANTENNA
Follow these steps to connect the RG-6 coaxial lead-in cable to
the antenna.
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 termi-
nals 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.
3.  Tape  the  transformer  and  coaxial  cable  to  the  antenna 
boom using plastic tape. 
1.  Attach  one  of  the  coaxial  cable’s  F-connector  ends  to  the 
supplied  matching  transformer.  Use  plastic  tape  to  weath-
erproof  the connection. 
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.
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.
