I assume you mean panel antennas. If so, I just added up the total
cost of one of every antenna on the:
http://www.fab-corp.com
web site (excluding the quantity bundles, and connector variations).
That's 10 antennas for a total of about $600. I'm sure FAB
appreciates your business.

True. Signal Seeker is not an antenna. It's a radio with an antenna
attached. Comparing that to just an antenna is a waste of time.

Make and model? USB or ethernet? No reason to keep the competition
name secret. Let's see what Google can find. One of these perhaps?

If you can see lots of networks, perhaps the reason it can't connect
is that they're encrypted and don't allow connections?
Does your purchase of such a competitive device imply that you're
going to do a side by side comparison test? If so, I can recommend a
few simple tests that will establish the relative differences in
performance. Actually, one is very simple. Locate an access point
with a very simple antenna at some location in the open. Connect a
computah to the access point that is capable of serving large files.
Connect your test radio to a laptop and download large files while
measuring the thruput speed. Start very close to the access point and
move backwards. Record the speed at convenient distances out to as
far as you can easily measure. With a big antenna, this can easily be
miles so be prepared to deal with long distances. Make a graph of
distance versus thruput. The graph will be jagged because of
reflections, multipath, interference, and such, but will give a good
idea of the distance versus speed tradeoff. If you need setup clues
or benchmark software, please ask.
>The

I can't resist a joke. I was in a shop that sells cell phones and was
listening to the salesmans pitch line. He was comparing cell phones
for a customer that was obviously clueless. So, he declared that one
particular phone was more "powerful" because it showed 5 bars instead
of 4 bars for the cell site. Never mind that they were radically
different phones, with totally different signal strength to RSSI to
number of bars conversion algorithms. How many microvolts or dBm
receive signal equals one bar?

War driving? Does it work with Netstumbler under Windoze 98/ME in
native mode? Does your USB radio include an NDIS 5.1 driver for
Netstumbler on W2K and XP? Does it work with Kismet (Linux)?
>I have great response from

That would be me, but I wouldn't exactly call my comments static.
Most of my comments are requests for detail and numbers, some of which
you previous promised.

I, on the other hand, know that aperture size limits antenna gain for
panel antennas and that as long as the patch antenna is not built from
more than 2 layers, the gain will be directly related to the aperture
size, which is the active antenna area. Download MStrip40 for a
suitable simulation:

Thruput vs range as previous described would be a good start.
Compare with competitive radios and antennas. Throw in a simple
laptop with built in MiniPCI radio or PCMCIA for comparison. Measured
receive sensitivity and transmit power output (EIRP) would be nice,
but will require quite a bit of test equipment. I'll settle for
thruput vs distance.

It's not considered polite for me to question your motives. However,
please note that if you really, truly, genuinely want to do battle
with me, answering some of my requests for details and numbers would
be a good start.
>My feed back from people

I've been involved with many manufacturers and product over the last
35 years. Very few people write unsolicited comments of praise. One
mail odor and online company I just checked shipped to about 10,000
active customers last year, and received about 40 email and written
messages of praise. I know because the company posts these on the
company bulletin board. Everyone reads them. Most of the customer
feedback is in the form of complaints, shipping issues, tech support,
and requests for additional info. The number of unsolicited comments
of praise you supply seems a bit excessive for your size company.
Also, your postings all show problems in grammar and spelling, which
also appears in the alleged customer feedback. The similarity to your
style and to other alleged comments on the eBay site, make me suspect
the origin of your customer testimonials.

Now wait a minute. I said that your antenna has a definite receive
advantage over system with a connecting coax cable. Everything else
is problematic, but the receive advantage is certainly there.
Incidentally, on the topic of understanding wireless, I do which you
would use dB, dBM, and dBi in their proper places. They're not
interchangeable.
