Antenna tweaking

Last Updated or created 2025-08-21

A while ago I was playing with LoRa (Long Range radio), I made a simple setup which worked good enough.

After that I installed Meshtastic

I also used OpenMqttGateway with LoRa.

I’ve been using antennas also with SDR(Software Defined Radio.

Not happy with the performance, I bought a Nano-VNA.
(Vector network analyser)

Due to the many options, I was lost at first. Maybe I have to ask Bigred.
Calibrating I get now, but I can’t easily calibrate an antenna with fixed cable.

Much to learn, but that’s what I want. 🙂
