Hello, I'm new to the forum and I'm already researching at some time on how to match antenna impedance. I am developing a 433.92MHz remote control that transmits in OOK modulation to a receiver that upon receiving the signal triggers some loads. My question is the following to carry out the marriage of impendancia of the line with the antenna so I saw a VNA is necessary, but this is a very expensive equipment, so I do not have access. Could someone help me with some alternative way that does not use VNA to accomplish this?
