Here's a good one.
A fellow Grumman owner, Horatio (the name is changed to protect the innocent),
has always complained that his radios (comms) are really bad. He can hear
sometimes, but not always. He can be heard almost never. Last year he went to
Canada and was in fear of being shot down for crossing the border without
talking to anyone. Oh, he tried, but couldn't reach anyone. He told me that,
for the most part, the range on his radios was about 10 miles. He does have 4
GPSs in his plane though.
Dave had his antennas buried years ago. But, never really knew where. Last
year, he found them: one was in the wing tip, the other in . . . . hold that
thought. The one in the right wing tip looked kind of like a flat 12"x12"
aluminum Christmas tree ornament. Last year, he came to me and asked me to
install install another one of these ornaments in the left wing tip. I laughed,
of course. There was no way I was going to waste my time installing another
antenna that doesn't work. I told him I'd install two antennas in the dorsal
fin if he wanted buried antennas (he was reluctant because he'd have to get it
painted.) He hemmed and hawed for months, finally agreeing to the new antennas.
I prepped the dorsal fin channel and waited. He showed up yesterday. We went
to work. What I found was amazing: lots of cutoff coax going into the spar and
then going nowhere and an antenna in the right wing root. Yup. The second
antenna was attached to the honeycomb bulkhead in the wing root. Put it this
way, when you first step onto the wing walk, your first step is where the
antenna was. I found the LORAN antenna in the other wing root. They had to
have been installed with the wing off. I could not get to the screws. I had to
cut the nuts off with a Dremel and then cut the antennas in half to get them
out. The coax was sealed with some sort of epoxy where it goes into the cabin.
I wonder what he'll do when he's able to hear ATIS or AWOS 80 miles away. He
may fly out of the local area again.

With the dorsal fin hidden antenna I find there is a blond spot. It's prett
y bad sometimes. I had to relay ATC to Stu, who has the hidden ant, and have
to use the belly ant during all xcountries while using flight following. Th
e dorsal ant works great for forward towers but loses aft towers quickly
Just a heads up......

With both antennas in the dorsal, the most forward antenna is acceptable aft.
I've found I can hear those behind me, but they can't hear me. I just roll out
and transmit, then roll back.
