Considering the time you spend building your own antenna with
unknown performance (not everyone has a 3 Gig SWR meter laying
around), you're better off buying a much better antenna.

15 dBi backfire antennas for $30 or 19 dBi "BBQ" grid for $40.

It would be nice to have a link to these.
Also, availability or price could vary per region, Shaun for
example is in New Zealand.

Exactly. Even though we're just a few hours by 'plane from LA we only seem
to get <35% of the stuff that folks in the US have available to them
imported here.

Granted, but without being able to definitely measure your
antenna's performance; its going to be a lot of trial and error.

A lot of wifi gear does have signal strength reporting
functionality. While it's not perfect, it's a good start.
Plus, in the end it is a matter of whether it suits the
need. If one needs 2 miles only then whether it couldn't
link at 20 miles versus a professional solution that could,
isn't necessarily important.

Just the other day I drive past an old satellite dish
someone was throwing away. I came quite close to chucking
the thing in my truck and rigging it with a router (acting
in access point mode) to see what kind of signals I'd pick
up. But alas, it's winter and too cold and icy to be up on
the roof and I'm the kind of person who needs to follow
through on a project fairly soon, if I had to wait a long
time it gets shelved and just clutters up the basement. I
HAVE to clean out my basement soon, LOL.

Unless the chip set actually has a signal level output, its
usually going to only show you the signal to noise ratio,
which is good enough if you test it where you know there
isn't any interference.

I keep a notepad in the truck with addresses where I see the
old abandoned eight foot dishes, anticipating they would be cool
to play around with. I figure a simple A-frame gin pole on the
back of my truck could take them down in short time. An 802.11b
moon bounce would be pretty neat (after tweeking for the latency
delays).

Sometimes the solution can be good enough in the only way
that matters, whether you can get sufficient strength from
point A to point B where you need to use it. There may not
be a need to find what is *best*, nor even have any accuracy
at all in measuring it, it is a means towards an end. It
just has to work.

Already have a shed, dont' want to drag everything back and
forth as workshop is in the basement. Can't attach anything
to the house.

Much of the 802.11 gear I've worked with has a field named RSSI
somewhere in the diagnostic info that can be printed by the software
that comes with it. RSSI means Received Signal Strength Indicator
anywhere I've encountered it. So that's a measurement (in possibly
arbitrary units) of signal strength, not simply signal to noise.

I have two drivers for my US Robotics WiFi. The later version has
readings for both signal strength and signal to noise ratios.

It is quite possible one of these other businesses had put a
repeater on their roof so they could enjoy using their
account inside without having to pay for on-site service.

The only way you could more reliably know for certain is to
take a wifi locator, signal strength meter back down there
and canvas the area looking for more spots not on maps.

It is certainly possible for signals to go 800 feet outside,
line of sight, but more surprising if you're inside the
sandwich shop, even moreso to maintain connection with a
laptop and do that in a shop where there might be a kitchen
with microwaves.
Click to expand...

It was a Subway sandwich shop, so I don't think they had any microwaves
going. And I was (accidentally) sitting right by the window that was closest
to where that hot spot would have been. So it was almost like I was
outside -- the laptop was right next to the window.

Also, as noted, I only had one bar out of five. Still, I was able to surf
without any problems.

So, Neil
I think you were very successful getting responses for a stupid question,
and stretching it out by your responses.

For a troll you did very well.

I take it you don't have any friends to hang out with during winter break
from school.

Are you talking about yourself here? Because, obviously, if you had friends,
you'd be enjoying time with them, rather than wasting time in a thread that
you feel is "stupid." I'm just sayin'..
