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.

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*

The DX Commander Signature 12.4 is an All Band Vertical HF Antenna that covers 9 bands from 80m through to 6m. It is an economical and efficient way of getting on every HF band easily with a nice compact vertical antenna.

The antenna is basically a fan dipole, but rather than horizontal, it is vertical quarter wave elements in parallel on a common driven element base with short ground radials.
