Okay I don't have fancy spectrum analyzer. As a matter of fact I don't
even have
anything besides HF radio. The other day I got a chance to look into 5.7
GHz
wireless antenna and I couldn't believe how compact it was. If that
device was
installed on my ceiling, I doubt I would have seen it. It was the same
size as
2 cigarette packs. And it could transmit signals well over 3 miles. Wish
there
was a easier way to detect RF signals. Any help?
