Coax Cable Impact

Without a coax cable attached to the high input the power enveloppe of a close by Mobile Phone Base Station is just visible using MAX DECAY

The signal under marker 1 also is from the mobile phone base station.

As soon as you connect one of the supplied coax cables to the high input and leave the other side open this changes

The power envelope and the signal under the marker increase with almost 20dB

Replacing the supplied coax with a double shielded coax, costing more than the tinySA, shows the shielding of the supplied coax is not perfect as the power envelope reduces to (almost) the level without coax cable attached.

So be aware many coax cables are far from perfect.
