3
Interconnections
Installation
1. Locate the tuner in a convenient location at the operating position. Avoid placing the
tuner near microphones, speech processors, computers, TNC's or other RF sensitive
devices.
WARNING: If random wire or balanced feeders are connected directly to this tuner,
position the tuner so the rear panel terminals can not be accidentally
contacted by persons or conductors. When transmitting with random wire
or balanced lines, the rear panel feed-through insulators can operate with
high RF voltages. These voltages may cause serious RF burns. These
high RF voltages may also damage anything contacting or within a half
inch of the terminals.
2. Install the MFJ-948 between the transmitter and antenna as shown in the diagram
above. Use a 50 ohm coaxial cable to connect the transmitter or transceiver to the SO-
239 (UHF female) labeled TRANSMITTER on the back of the tuner.
3. Coaxial feedlines attach to the SO-239 (UHF female) connectors labeled COAX 1 and
COAX 2.
4. A random wire (longwire) antenna may be connected to the five-way binding post
marked WIRE. See the ANTENNA HINTS section for detailed suggestions on
bringing a single wire feeder into the operating position.
