If your combination antenna has a 300 ohm twin-lead wire,
use the 300-75 ohm matching transformer (not supplied).
Combination VHF/UHF Antenna (Separate VHF
and UHF 300 ohm twin-leads)
Connect the UHF twin-lead wire to a combiner (not
supplied). Connect the VHF twin-lead to the 300-75 ohm
matching transformer (not supplied). Attach the
transformer to the combiner. Attach the combiner to the
antenna jack.
Separate VHF/UHF Antennas
Connect the 75 ohm cable from the VHF antenna and the
UHF antenna twin-lead to a combiner (not supplied).
Attach the combiner to the antenna jack.

For Subscribers to Basic Cable TV Service
For basic cable service not requiring a converter/
descrambler box, connect the CATV 75 ohm coaxial cable
directly to the antenna jack on the back of the television.
For Subscribers to Scrambled Cable TV Service
If you subscribe to a cable service which requires the use
of a converter/descrambler box, connect the incoming
cable to the converter/descrambler box and connect the
output of the box to the antenna jack on the back of the
television. Follow the connections shown left. Set the
television to the output of the converter/descrambler box
(usually channel 3 or 4) and use the converter/descrambler
box to select channels.
For Subscribers to Unscrambled Basic Cable
with Scrambled Premium Channels
If you subscribe to a cable service in which basic cable
channels are unscrambled and premium channels require
the use of a converter/descrambler box, you may wish to
use a two-set signal splitter (sometimes called a "two-set
coupler") and an A/B switch box from the cable installer or
an electronics supply store. Follow the connections shown
left. With the switch in the "B" position, you can directly tune
any nonscrambled channels on your TV. With the switch in
the "A" position, tune your TV to the output of the converter/
descrambler box (usually channel 3 or 4) and use the box
to tune scrambled channels.
