Pierrre,
You'll probably get some good answers from those building Visions if you
direct your question to the Vision Builders list.

A very good source for info on antennas is RST Technologies.  I notice
that they don't sell outside of the US, but  I think you'll find some
good info there.  Jim Weir (owner of RST) has written many articles on
antennas and antenna placement in fiberglass aircraft, you might find
more by googling his name.  http://www.rst-engr.com/

Great airplane--good luck

Mark/ Pierre,
I don't know if the Vision web site is down for you but it is down for me.
I
contacted Steve directly and he's chasing it up with the host. I think
it's
hosted through one of the builders who has access through  a college or
school.
Pierre, it might be appropriate to contact Steve directly as I've have
seen
this info available on builders discussions.

Hi Guys;

My name is Bob Archer and I do aircraft antennas, only internal zero drag
aircraft antennas. I retired a few years back after 35 years of designing,
building, testing and installing spacecraft antennas. A fellow worker and I,
both of which were into aircraft decided we could do better antennas with no
drag so started up a company. My partner split and left it to me so I am it.
I have many papers I have written on the subject of internal antennas and
would be happy to share with you folks. I will attach a sketch of how to
make Nav and Com antennas with a proper Balun. This drawing was writ by hand
many years ago and I have never updated it. But it does show the proper
information if you can decipher it. I have two Vor antennas of this design
in my airplane and at moderate altitudes recieve the Vor signal from about
135 miles. Lancair IV-P flyers claim 200 miles or better on my antennas at
20K ft.

I will also attach a product list with prices. And I will attach a paper on
the subject of Com antennas for composite airplanes. I have almost a full
page in the Aircraft Spruce Catalog.

I will be happy to answer any antenna questions that I can. BTW do NOT
bother trying to use ferrite beads as a balun, that does NOT work!

Regards

Bob
