5. Twist the free ends of the wires from the microphone cartridge
   together and feed the microphone wires through the PVC fittings from
   inside the parabolic dish until the end of the wire reaches the^3 ⁄ 8 " hole.
   If you have trouble pushing the wires around the 90° turn, take a stiff
   wire with a hook shape in the end (we used some 10 gauge wire; many
   building supply stores will sell you a few feet of this) and pull the wires
   through the PVC fittings and pipe.


6. Use a piece of 20 or 22 gauge wire with a hook shape on the end to
   pull the wires from the microphone cartridge through the^3 ⁄ 8 " hole.


7. Pull the wires through the^3 ⁄ 8 " hole, leaving enough wire inside the
   parabolic dish for the microphone cartridge to reach the 1^1 ⁄ 2 " washer
   with about two inches of slack left over.


8. Cut the wires to allow three inches to extend from the^3 ⁄ 8 " hole in the
   pipe and attach each wire to a right-angle phono plug, as shown in
   Figure 6-14.
   You can use either a plug that requires soldering to the wire or one that
   uses a screw to secure the wire, as we did here.
