I've got too many antennas lying around, I can no longer remember what they were for. 50MHz? 144MHz, 430MHz? Dual band? Single band? Not a clue. I've ordered a £30 NanoVNA (vector network analyzer) off Amazon, arriving tomorrow with Prime. It looks like one of the many cheap VNAs on Ebay/Amazon but reviews are very good.

Now it's time to take the FT-818 out for fun.
