Abdullah:

I appreciate that you are not an EMC expert, nor a top expert in antennas.
However, I would expect anyone with a basic electrical engineering,
electronics, or physics education to recognize the following: The antenna
is not assembled according to any known design. Thus, it will not exhibit
performance necessary to conduct and document traceable measurements.
Neither the forward gain nor the shape of the pattern is known to the
necessary accuracy. Characterizing what amounts to a random collection of
metal will be more expensive and time consuming than to simply discard the
incorrect antenna and purchase one which is correctly assembled. Will your
lab be required to pass an inspection by a National Agency before your
measurements will be accepted? With the antenna assembled as you describe,
it will not pass inspection.

All of the above comments are based on information which should be available
to and known by an undergraduate engineer in any of the several disciplines,
and that is the reason for my original comment.

Ask them for a refund, and drop them from your vendors list.

What effect did it have? Sorry to say this, but it sounds like you
are going to spend far more money doing it yourself than if you had
simply farmed out the job to a real lab that was registered with the
FCC.


Our company is *setting up* a lab that will provide an EMC testing
service for other companies. We are in Turkey, so I don't think FCC
covers here... (and it's not as easy as "drop them from your vendor
list", there aren't that many companies or specialists that we can
"pick and choose")

I wish someone would answer the question "what would the effect of
this mistake be?" If there is no effect, then I'm wasting my (and
your) time... Thanks!
