Thanks for posting that, the Nano VNA is an amazingly useful bit of test gear. I tried it and it works a treat.

Yet another (similar) example of why you may need to measure the coax length with a Nano VNA.

Good example of using phasing to control radiation pattern. For his repeater site, I can see downtilt being an advantage, but for Mt Wombat and a 6 dB SMD array the pattern is better with zero downtilt. The four bay binary from RFI can be ordered with optional downtilt, which is sometimes preferred for commercial sites.

Good video.
