Change your wiring, if needed/possible.

At least change all the plugs to properly mounted F plugs.

Remove all supermarket grade splitters, with and without power, use
instead high-grade splitter, low insertion, using F plugs.

Install a proper masthead amplifier, as close to the antenna element of
your aerial as possible. Make sure that the power supply injector is
properly connected.

Make sure that you are using the LNA on the Nova-T 500.
