[C320-list] GPS Antenna Installation

My advice is - don't.  It is better to mount the GPS antenna near the centre
of the boat to reduce motion of the GPS antenna.  (Helps the receiver by
reducing the doppler that it has to track.) )  Actually, you will find that
the GPS receiver works with the antenna in the saloon under the roof but
reduces the already weak GPS signal, by how much I don't know.  Or mount the
antenna on the pedestal to make life easier for yourself.

I'm installing a chart plotter on the pedestal and will be mounting the GPS
antenna on the pushpit starboard side of the ladder.  From inside the
starboard aft locker I'm able to get a drill to the underside of one of the
pushpit's "stations".  When I drilled through the fibreglass from the
underside about two shot-glasses of water came out which I found strange.
Anyway, past that point the going got extremely difficult and completely
dulled five titanium drill bits in no short order.  I then tried with a tiny
bit which has unfortunately broken off up in the hole which I cannot get
out. I presume I will have to abandon that hole now and try another route. I
would think I'm encountering problems because the stainless steel tube is
welded to the flat mounting bracket and there could be a big glob of wend in
there at the base.  I was also planning on using this route as a feed for
the starboard observation seat speaker as my boat is not prewired like later
models.  Can anyone tell me how you managed to drill through this very tough
material?
