I mostly replicated this experiment at a gig during some downtime yesterday. Very interesting. Thanks for posting!

Another reason to "see the world from the receiver's perspective" is that receivers, active splitters, active antennas, etc. will all generate intermods where a simple antenna into an analyzer will not. So, in effect, you can see something opposite than your images show, specifically more IM frequencies.


Whenever possible, I connect my analyser to the antenna splitter output.

Most receivers have more sensitivity than you need.  It's all about signal to noise.

Been very busy in the trenches lately ....
Really cool stuff!!  What kind of attenuator did you use to protect the scanner from the high level signal of the distribution amplifier?

None, there usually is a small level gain with UA84x units, but not enough to warrant padding the inputs.

BradI know that curiosity killed the cat, but what device did you capture the images from?Brian

RF Venue Vantage (Mac) with a RFExplorer unit.
