Pretty sure both our transponders are now using the short fins.
One of them is a Garmin unit receiving data.......

Good Morning Moe,
Most often a shark fin is a high speed communication antenna. They
create relatively low drag and handle ice very well.
The dual "shark fins" that are occasionally installed as a pair and
oriented horizontally are generally called Blade Antennas. They are used
to receive VHF Navigation and glideslope signals

Fellow Commander Drivers:
Typically which radio is connected to the "Shark Fin Antenna" I
seem to be having a senior moment and can't remember.
Thanx!

Subject: Re: Commander-List: Flying with doors removed.
Hi Bill,
Last week I managed to track down the research for the arrangements
that the Department of Civil Aviation put in place, here in Australia
back in 1962. At the time they were operating 2 560Es and 2 680Es.
They conducted significant air testing of a 560E with both the
baggage door removed and the emergency exit window removed. Their aim
was to enable operations in a Search & Rescue environment.
Their conclusion was simple: Baggage door-off or window removed or
both were permitted provided a 10% reduction in AUW was achieved for
take-off, and across the operational envelope.
Hope this helps...
Cheers from Oz
Russell

Bert, that information would be very helpful if you can send it. I
am also wanting to fly with the baggage door removed.
Thanks

Good Morning Steve,
You are probably correct!
I had forgotten about those itty bitty "shark fin" antennas.
They are generally mounted on the belly and are used to receive data for the
transponder or DME. Some anti collision units use an additional one mounted
on the top of the fuselage.
They handle the same job as do those short (two to three inches long) wire
antennas that are so easy to break off when washing the airplane.

That is amazing.
I can think of all kinds of small part off a TC that can be built again.
Door Handles?
Control Wheels?

I had to order =BD of a rear door hinge for my 500S 3 years ago and it
cost $950.00. We didn=92t use it as it would have required dismantling
the door to replace it. My mechanic was able to weld the broken one
(for the second time) and we had to keep the hinge as the supplier
wouldn=92t take it back after the 2 weeks that we had it.
It seems that a technique such as this would be perfect for this
application. Of course it would depend on the end cost for one part.

Subject: | Re: Shark Fin Antenna |
Hi Old Bob..... Right now we've got a Mode-S transponder running with
TIS-B traffic snooping. Its completely dependent on a data uplink from
the ground..... And if I've got it right, it's using one of the little
fins to recieve that data.
ADS-B I'm a guessin' we'd have another antenna on top to cover the air
to air exchange of data we don't have now. So far TIS-B has been a nice
pair of extra eyes in the cockpit with us when working, and covers most
of the busier places we fly.
P.S. I think those little shark fins break off even easier than the
little whips do. Be careful dragging a preheater tube under the
aircraft. (That one wasn't my fault for once!)
