cause interference in the form of moving ripples or diagonal streaks.
Television or FM receivers operating near your receiver, can also be the
reason for this reaction. (Fig. 8.)

[Illustration: FIG. 8]

The insertion of a filter trap at the antenna terminals of the TV
receiver will sometimes eliminate or reduce this type of interference.

Antenna Connections

1. FOR POSSIBLE BETTER PERFORMANCE
CONNECT ADDITIONAL WIRE TO REMAINING
ANTENNA TERMINAL

TV RECEIVER]

An outdoor type antenna is recommended for best reception. If such
installation is impossible, different type indoor antenna may be used.
Quality of reception also depends upon local signal conditions.

Some models are equipped with a di-pole or mono-pole antenna mounted at
the cabinet back. To use this antenna, raise and extend rods. Vary the
length and position of the rods or rod for best picture and sound.

Under favorable receiving conditions, satisfactory reception may be
obtained with a 10 ft. length of antenna wire. (Supplied with some
models). Stretch out wire for best reception.

When using a regular outside antenna, disconnect the inside antenna
leads from the antenna terminal screws. Connect the antenna transmission
line to both of these terminal screws.

THE PROOF OF ZENITH ANTENNA SUPERIORITY IS IN THE PICTURE.

Zenith TV antennas are designed and constructed to provide you maximum
service and superior performance. Contact your Zenith dealer for the one
that will provide you with the best picture quality.

DIPLEXER

(SEE PAGE 8)

When using a combination VHF-UHF antenna system with a single
transmission line it is necessary to have an additional diplexer at the
receiver.

Make the transmission line lengths from the diplexer to the VHF and UHF
antenna post terminals on the receiver as short as possible. See your
Zenith dealer for additional information.

OSCILLATOR ADJUSTMENTS (VHF)

=NOTE:= _The VHF perma-set tuning control on the tuner is also the VHF
channel oscillator adjustment._ No additional oscillator adjustments are
incorporated. Therefore, should re-tuning of a VHF TV channel be
required, select the channel and then manually turn the tuning knob for
best picture and s
