Ok, that's sound better, having only part of the antenna sticking out. But it is kind of contradicting what I read in Dave's link. And I understand that since focusing on infinity it is less of a problem, but still annoying and unaesthetic to have the hole dipol antenna in front of your eyes all the time.
I would like to see more photos of brick antenna and remote display installations.
Also, what about external antennas near the gear similar to transponder antennas?

I talked to Dave about this at Mifflin.

Like you guys, mounting the coax and center part under the instrument
panel with one end of the dipole sticking through a hole seemed like a
sensible compromise. It also addresses the issue that you Will Not
Install anything that is stuck to a Schleicher glareshield, otherwise
the canopy will not release in an emergency. This is a serious issue,
Sailplane and Gliding reported a fatal crash a while ago because a
pilot could not release the canopy to jump out, with pda wires holding
the canopy on.

At Mifflin, Dave said no, no, no -- the antenna needs to be higher
than that. Some more official confirmation would be nice -- we really
need to try that kind of installation and see what the range is. One
of Dave's issues is that a lower antenna will be blocked by instrument
cases and all the other metal that is behind the glareshield. A good
point.

And as the other say...c'mon guys, surely there is a better solution
somewhere at Antennas R Us.

I plan to install the brick with this silly antenna, and hope that if
we all keep complaining flarm will come up with something more
acceptable. Replacing antenna will be easy.

The antennas supplied with PowerFlarm appear to be off the shelf
commercial stuff. They're functional, but hardly ideal.

Here http://www.linxtechnologies.com/prod...ipole-antenna/

is a 900 MHz dipole that although a bit long (4.5") is at least very
thin one way (3/16") and locates the coax feed on the end. With just
a little bit of sailplane application specific engineering, much less
obnoxious designs are surely possible.
