1. Cut four 6" pieces of wooden dowel.


2. Cut a slot about one-third of the way through each dowel,^1 ⁄ 4 " from
   an end.

The slot has to be wide enough for the washer to slip into.

3. Assemble the dowels and washer in the parabolic dish, as shown in
   Figure 6-12.

Use cable ties to hold the dowels in place. If you are doing this by your-

self, it can be kind of a struggle, but it is doable. Getting another person

to hold the dowels in place while you put the cable ties on it will simplify

your life.

4. Solder an 18" black wire to the ground pad of the microphone car-
   tridge and an 18" red wire to the +V pad.

Figure 6-13 shows a cartridge before and after soldering.
