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?
