The last issue of Velocity Views had an article from Scot Baker about
Stormscope antennae installation on the underside of the pilot side
wing. It was suggested that the antennae cable would have to be cut and
spliced if one wanted removable wings. Because there is two separate
layers of shielding in the cable, only a pro can do the job. The factory
will splice it for $300 if one sends in the cut cable after going to the
trouble to disconnect it from the control unit. Will a spliced cable
ever work as well?

I wondered if there weren't a better way. Here is another option. Simply
enlarge the wire channel 31" into the wing from the inboard end of the
wing so that the cable can be passed in and out of the wing to the
antennae . After getting a blessing from the factory, I employed the
following process:
=20
1. Open the hole for the antennae into the channel as instructed in
the Views. (I was relieved that the channel was where it was supposed to
be 31" from the inboard edge and 4" toward the TE from the center spar.
To double check this location I noted that the drill point was right on
a straight line from the entrance of the channel on the inboard side to
the outlet of the channel at the strobe light on the other end.)
2. Fish out the strobe light, nav and com wires through the newly
cut hole so they won't be in the way. the later step of trying to cut
through the foam around the wires doesn't work. Don't ask how I know.
3.Enlarge the inboard fiberglass opening of the channel to 1.75 "
4. Sharpen the end of a 1.75 OD X 40" aluminum tube and pass it up
the foam surrounding the channel. It helped to re-sharpen the tube every
10" of foam cutting since the aluminum doesn't hold an edge.
5. Pass the com/strobe wires back out the channel.
6. One could leave the tube in place for ease of passage of the
cable. I am trying it without the tube first.
