On the Schleicher ASH-26E, there isn't enough room above the
glareshield to allow clearance for the PowerFlarm antenna - - it's not
supposed to contact the canopy. This, and to avoid it blocking the
view or panel, required making a shelf bracket to extend aft from the
glareshield lip and also to allow the PF to mount a bit lower. This
has the added advantage of bringing the control knob a bit closer to
the pilot for easy access.


I made the bracket from aluminum with a curved portion to mate with
the underside of the glareshield, TIG welded to the bracket shelf. The
curved underside mount could be made of wood and the shelf screwed to
that if TIG welding isn't available. Links to pictures:

That bracket looks a little...uh... "undesirable" in the event of a
bail out. *My $0.02.

The bracket (and PowerFlarm) "goes away" with the canopy in the 26E,
so there is a break-away plug under the glareshield so the canopy
eject process won't be impeded should I decide not to try landing the
remaining glider bits.

The bracket is .050" aluminum, and even if used on a glider such as
the DG-800 series, where the pedestal stays put, would easily bend out
of the way. Is could, if need be, be mounted with frangible nylon
screws or 3-M mushroom style interlocking tape.
