Setting up the AM Antenna

* Insert the claw on the bottom of the antenna into the groove in

the leg.

* Place the antenna on a level surface and rotate it to locate the

orientation that yields the best 'reception,

¢ To permanently

fix the antenna,

screw

the leg to a wall or

something similar before assembling (fixing the antenna in the

direction that gives the best reception).

EXTERNAL FM ANTENNA

The main advantage of FM over AM is the quality of the broad-

cast signal. In order to benefit fully from the high signal quality of

FM broadcasts, it is recommended that a special-purpose FM an-

tenna be installed. In weak signal areas, a multi-element (3 ele-

ment, 5 element,

7 element, etc.) antenna should be used.

FM OUTDOOR ANTENNA CONNECTIONS

There are two ways of connecting the FM antenna to the antenna

input terminals: with a 300 & twin-tead feeder or with a 75 Q

coaxial cable.

To get the most from the receiver performance, a 75 Q coaxial ca-

ble is recommended since it is more immune than the twin-lead

feeder to noise and interference from external sources. If an FM

antenna has already been erected outdoors, connect it, referring

to the figure.

GROUNDING

Grounding is recommended

if reception of FM programs is im-

paired by noise. To ground, connect a thick polyvinyl insulated

wire to the GND terminal and attach the other end to a metal

water pipe or grounding bar or wind it around a copper plate and

bury it.

NOTE:

terminals

Never connect a wire to a gas pipe for grounding since sparks

may ignite the gas.

EXTERNAL AM ANTENNA

If it is not possible to obtain adequate AM

reception even by

changing the orientation of the AM loop antenna, a separate in-

door antenna, or an outdoor antenna should be installed.

INDOOR AM ANTENNA

Use a vinyl insulated wire (5 — 6m:17

— 20 feet} and connect

one end to the AM antenna terminal and affix the other end to the

wall or ceiling, as high as possible.

OUTDOOR AM ANTENNA

If reception quality is not improved sufficiently even when an in-

door antenna is used, a viny! insulated wire should be installed

outside and fixed in place.

NOTE:

Do not detach the AM loop antenna when using an indoor or an

outdoor AM antenna.
