Because its certified system, not certified radio. Many of the
manufacturers do not provide antennas that are always available.
Just this month, Trangos DSS dishes were not available, it was buy your own,
or don't earn revenue for a month.
Or use a Andrews 3 ft dish with better RF characteristics for avoiding
interference with/to others, apposed to the inconsistent certified brand
that have higher wind load and higher price.
Sometimes the more responsible thing to do is to use the better choice, even
if uncertified. Because times change quick, and manufactuers do not always
keep up. If more manufacturers tested common antennas more quickly, this
problem/thread would not exist.
But why should the manufacturer eat the cost to test antenna manufacturer's
products, why not antenna manufacturers test with the radios?

No need to push manufactures when you can just not buy their product. Why
would you want to take the business risk of not buying a certified radio?
I mean Trango sells radios plenty cheap and they're certified. Canopy is
also cheap and also certified.

This sounds like a good idea. I am sure we could add a link to a listing
of certification labs. We also need to push manufacturers to certify.
Without some pressure from us the certification will just look like more
cost with little to gain to manufacturers. Pressure from customers would
make this more of a requirement than what it seems to be now. If we all
insist on certs then the overall cost for this would be negligible.

John,
Should WISPA consider publishing on our website a list of certification
labs? It seems that our industry needs someone to step up and take on a
leadership role and WISPA seems (to me anyway) to be the perfect
organization to perform this role.
We could start by simply polling our list members to see which labs
anyone has used and been satisfied with.
OK, speak up guys (and gals). What lab or labs have you researched or
used?

The rules state that any radio / antenna combination has to either be a
certified system or that a substitute antenna used would have to meet
the same specs as one used for certification in a system. Many think
that this means "anything goes". The truth is that there are almost
certainly a good bit of installed systems which would not pass FCC
enforcement inspection. Many believe that following maximum EIRP rules
is the only requirement. This is not so. It is a good practice if you
are not following the rules but that does not mean it is legal. Another
common belief is that "anything goes" is the rule of thumb due to the
general lack of enforcement in unlicensed bands. This is unfortunate
and further illustrates the need for our industry to mature.
Part of this maturity process should start by operators demanding to
see FCC certifications for the systems they buy. It is tough for
operators to remain compliant when so few systems are certified.
Another step should be that manufacturers certify their systems with
commonly used antenna / radio configurations every time they release a
product. Finally, distributors need to demand that all systems they
sell meet certification requirements. The fact is that certification is
not terribly costly or complicated and should be a step taken by all
manufacturers and eventually all of us. If anyone here represents
manufacturers who certify all their systems then now would be a good
time to toot your horn.
I believe the day will likely come that the FCC will inspect WISP
systems. It took them about 20 years to start cracking down on the
cable television industry for signal leakage and other infractions.
Something tells me this industry will not have to wait that long. Of
course the decision to follow the rules is inevitably up to each
person. I would like to think we all will be compliant in the future
but this is an unrealistic goal I am sure if manufacturers do not take
a leadership role in this effort. WISPA stops short of demanding that
members do anything but I will say, as President of WISPA, we should
all try to follow the law regarding this industry. No industry
association could expect to have impact in policy and legislative
efforts if they took the stand that shirking the law is a correct
course of action.

It sounds like several of you here build your own radios and use off
the shelf antennas. So if I buy a board, cards and an antenna what
are my obligations to FCC as far as having a certified system in
production? Thanks for the education
