Hi Ken

I am surprised at the -97dBm sensitivity.

Yea, it's a genuine Atheros card, not just an Atheros chipset. I bought it
based on reports online touting it's high reciever performance and the
fact that it is a mini PCI card, not a pcmcia card.


One of you other posters suggested remoting the router box to remove the
cable loss problem. It is the place where most of your problems lie.
Even moving it part the distance will help. You might also look at a
better coax. We use to use LMR400 extensively. It was much cheaper than
RG213 and lower loss as well.

That is what I was using - 40' of it.


Oh and be careful with the WAP etc setup as regards "maximum distance".
We had a problem early on where we left it at the default for a 10km
path and the ACKs (or something) kept crashing and kept the speed down.
The distance number introduces some kind of ACK delay..

Good luck!

Thanks for all the help, Bob - 73!

I tried to make the same antenna with 1/2" hardline & had several RF
analyzers to help me, it never worked out. This article helps
explain why coax wont work, I used wire and would my on coils for
phasing, i also took apart a Madrax antenna to get the measurements,
they used brass tubes inbetween the coils, not because its brass but so
the 1/2 wave length can be easily adjusted.

Hi Tucker

Thanks for reference to that great site. I really like that flat antenna.
