I am often asked: Where do I get a good antenna? Or: Is this a good antenna? Unfortunately, you do not see if an antenna is good or bad before you do some measurements. Or you build one yourself. That is what we will do today. Be it for satellite reception, for LoRa, weather balloons, or even for Wi-Fi. Like that, we know what we have. And even can save some money.
