It is an honour to meet you, your videos taught me so much about LORA and all things RF, Thanks for telling all makers to get a VNA even if it is a Nano, Yet to get my T beams, they should be here by next week while I wait, practising how to make 433mhz antennas of varying types and figuring out how to tune them, So far I have made 1 433mhz Folded end Dipole, please look at my readings and tell me what you think. Please see Finally got me a VNA (noobie)
