Attaching Ground Radial Wires to the SMBA-2 Shelf
Prepare the twenty 25 foot radial wires by stripping off insulation at one end and crimping a #10
Terminal Lug. As an option, the terminal lugs may also be soldered to help ensure positive
electrical connection and long life.
Using the 20 sets of supplied #10 stainless steel hardware (Bolt, Flat Washer, Star Washer, Split
Washer, Nut) connect the 25 foot ground radial wires to the
SMBA-2
shelf as shown below. (You
will use two radial wires on the corner nearest the insulator.)
Radial Wire Pattern
Bias "T" Connections
Refer to the MFJ manual for details on the Bias "T". The Bias "T" supplies the DC power required
in the remote tuner using the coaxial cable that goes from the Bias "T" to the remote tuner. The Bias
"T" is usually located in the radio room and has 12 VDC connected to it. Make certain the coaxial
cables are properly connected to the Bias "T" as shown below. Ensure the ON/OFF switch on the
Bias "T" is turned ON when using the system.
The customer supplied coaxial cable coming from the Bias "T" (located in the radio room) is
connected to the MFJ tuner SO-239 connector using the right angle UHF adapter (included).
