Locating Your Terk HDR-I
For Best Results

1. All antennas are affected by electromagnetic fields.
To maximize performance, position your HDR-I
antenna away from direct contact with receivers,
tuners, CD players, TVs and computers.
Note: Antennas work best when CD players, VCRs and
computers are turned off.
2. Keep the antenna away from large metal objects.
Placing the HDR-I near a window often provides the
best results.
3. On occasions, certain areas in your home may be
null points or dead spots where no radio signal can
be received. This may also occur in metal-frame
buildings and houses with aluminum siding. In this
case, simply move your antenna, trying different
locations, until the best reception is achieved.
4. In weak signal areas, optimum tuning is achieved
with your receiver’s scan button in the off position.

Remember that no antenna can receive a radio signal
that isn’t there. When a usable radio signal is present,
your HDR-I will improve AM and FM reception.
Note: Generally, a practical limit to radio reception is
40-50 miles from the broadcast transmitter depending on
the terrain.
Gain Control Knob
Located on the back of the HDR-I is the gain control knob.
The gain control is the mechanism that either increases
or decreases the antenna’s amplifier intensity. The
further away you are from the radio signal, the more you
increase the gain. If you are very close to the radio signal,
signal saturation occurs. Lowering the gain will decrease
the amount of distortion. See Fig. 5.

Q: Can I extend the wire on my FM antenna to place it on a window sill or
somewhere away from my receiver?
A: You can extend the wire with RG-59 cable and a two-way F connector.
These items are available at any electronics store.
Q: When I touch the antenna, it works better. How come?
A: When you touch the antenna and your feet are touching the
ground, you are acting as a giant antenna. You can only
accurately judge how the antenna is working when
you let it go.

Performance Specifications
Power Connection:
Plug the small end of the included power supply into the
jack located on See Fig. 4. Plug the large end of the
power supply into any working electrical outlet.
NOTE: When plugged into an electrical outlet, your TERK
antenna will remain “ON”. This is not a problem because
the AC adapter uses very little power. To turn “OFF” the
power supply, it must be plugged into a switched outlet.
Some late model radio tuners and receivers come with a
switched outlet located on the back. It is safe to use this
outlet for the TERK power supply.

Making Connections
With Your New HDR-I
FMGain
FM AM
DCPower
Radio tuners and receivers can have different connections
for your new HDR-I antenna. Please find the connection
that best matches your tuner or receiver and follow the
listed instructions.
FM Connections:
75 Ohm Coaxial:
Your TERK antenna has a Slip-On Coaxial connector on
the FM lead. Simply slide the connector onto the coaxial
terminal. See Fig. 1.
AM Connections:
Your TERK antenna uses a Twin Lead Bare Wire for
AM connections. If your radio tuner or receiver has a
Push-Button connection, simply slip the bare wires into
the push button connections. For a Screw Terminal
connection, wrap the bare wires around the screw
terminals and tighten. Please note that the black wire
should be connected to ground (GND) See Figs. 2/3.
