Using a NanoVNA to Fix Our Repeater Coverage

Post author By admin
Post date September 1, 2024

We’re phasing two dipole antennas together on our repeater system, but we need to add downtilt – to move the main lobe down toward our main users.
This is how you build a delay line to accomplish this using a NanoVNA.

NanoVNA Tricks: How to Accurately Measure Coax Length (EASY)

Post author By admin
Post date August 31, 2024

You can use a NanoVNA to measure coax length or distance to fault, similar to a TDR using the Transform function.

*Note the model I use is a NanoVNA SAA-2N – not the H4*
