How susceptible are the NanoVNA to Broadcast Interference?
My antenna test field is within 1 mile of two 50 kW AM broadcast transmitters at about 700 kHz and 1500 kHz.

Some of my work includes broadband HF, VHF, and UHF antenna design.
The HF broadband antennas are fairly large, on with more than 300 feet (100m) of wire length in the air.
So, there can be substantial undesired MW signals at the antenna feed.

I'm shopping for a NanoVNA system with ~3 GHz capability.
What is the power output of the NanoVNA transmit?

Any recommendations?
