TV  FM High Gain Mast-Mount Antenna UHF/VHF/FM 
Amplifier with Switchable FM Trap

This amplifier with Switchable FM Trap
provides up to 30 dB amplification of
signals from outdoor VHF, UHF, FM,
or combination antennas. This high
degree of amplification is necessary
when your antenna is pulling in signals
from weak or distant stations, when it
is positioned 100 feet or more from the
TV, or when a single antenna supplies
signals to several units — TVs, VCRs,
or FM receivers. 

Note: This unit only amplifies signals;
it does not enhance distorted or noisy
signals.

FEATURES 

Separate Amplifier and Power Sup-
ply Units
 — maximize operational effi-
ciency. 

Built-In Adjustable Gain Control  —
reduces signals by up to 10 dB to pre-
vent overload and allow custom
matching of amplification to signal
strength. 

Switchable FM Trap — reduces or
eliminates FM interference, which ap-
pears as a herringbone pattern on the
TV screen.

Power Indicator — lights when the
amplifier is operating, and goes out if
power fails or the connecting cable
shorts.

Special Automatic Protection Cir-
cuit
 — guards against cable shorts
and prevents damage to connected re-
ceivers.

Surface-Mounted Components  —
assure long-term reliability.
