B. Antenna and grounding

(A) Antenna

Installation of antenna and grounding is important for optimum reception of short-wave, broadcast or amateur radio signals. A good outdoor antenna will provide the best re- sults.

Caution:

Protect your Equipment Use a LIGHTNING ARRES- TOR.

Note:

A simple method is to install the wire antenna as high as possible, it must be extended to its full length for good re- sults.

ANT 1: UHF coaxial antenna connector

Use a low impedance antenna. The antenna feeder should be a coaxial cable equipped with a PL-259 connector.

ANT 2: 500-ohm antenna terminal

Connect a high impedance antenna such as a long wire antenna.

50-ohm antenna terminai Connect a low impedance antenna.

Note:

To connect both 500-ohm and 50-ohm antenna terminals at the same time may cause the receiving sensitivity worse.

C. External speaker

The R-5000 includes a built-in speaker. If you would like to use an external speaker, such as the SP-430, it may be connected to the EXT SP jack on the rear of the radio. The speaker may be any good 8 ohm permanent magnet type speaker. The diameter should be at least 4 inches for

A. Headphones

Any low-impedance (4 - 16 ohms) headphones may be used with the R-5000. Connect the headphones to the front-panel phone jack.

The optional HS-5 or HS-6 headphones are best suited for use with the R-5000. Stereo type headphones can also be used.

VHF ANT connector (Optional VC-20 VHF Converter is required for VHF reception.)

When an outdoor antenna is used the antenna feeder should be a coaxial cable equipped with a UHF connector.

Caution:

The VC-20 VHF Converter Unit should be installed by qualified service personnel to prevent personal injury or damage to the equipment.

(B) Grounding

Making a good earth connection is important for preventing dangers such as electric shock. Bury a commercially available ground rod or copper plate under the ground and connect it to the GND terminal. A thick wire, cut as short as possible, should be used for the connection. To make a good earth connection, connect the GND terminal to a grounded metal water pipe.

Caution:

Never use a gas pipe or electrical conduit pipe. Note:

A city water pipe cannot be used as a good earth in some cases.

good audio quality. If you plan on using a speaker other than the SP-430 it should be equipped with a miniature phone jack plug.

The internal speaker is disabled when the external speaker plug is inserted into the receptacle.

B. Tape recorder

This terminal may be used for recording broadcasts on tape. Connect it to the LINE IN jack of your tape recorder. The output level at this terminal is constant, regardless on the AF gain control setting.
