Default FLARM Antenna Hall of Shame?

Not to be confused with the Soaring Hall of Fame
for which nominations were just requested...
Though some FLARM installations perhaps deserve
nominations there too!

I've recently received a lot of requests for the FLARM
Antenna Hall of Shame advice, but sadly the original
web page got trashed. Urs and I started a technical
note with this information, never quite got finished,
but I've put the latest draft on my
Soaring Publications web page:
http://www.nadler.com/public/NadlerSoaringIndex.html

The direct link is:

The bottom line is:
- use the dipole antenna above your instrument glare shield/cover
- mount it as high as possible, usually back towards
the pilot to get well above instruments and front canopy edge
- mount it so it is vertical in cruise flight attitude
- run the coax cable diagonally away from the antenna;
keep it away from the antenna elements
After the first few minutes you'll never notice it,
and you'll get MUCH better range than alternatives.

Hope this helps,
Best Regards, Dave "YO electric"
