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 Happy Skies Old Bob AKA Bob Siegfried Ancient Aviator 628 West 86th Street Downers Grove, IL 60516 630 985-8502 Stearman N3977A Brookeridge Air Park LL22 In a message dated 2/26/2009 8:35:01 A.M.

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 On 20/2/09 5:48 PM, "BillLeff1@aol.com" wrote: Bert, that information would be very helpful if you can send it.

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.

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.

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!)
