Which antenna analyzer do your people use? I'm considering the NanoVNA-H4.
Thanks!
We have a NanoVNA. I haven't tried it but there are ways to use an SDR as an antenna analyzer. You just need to have something to calibrate it against.
Yeah, I've seen Zachmann's article. But it didn't appear to be very consistent; and the NanaVNA is "affordable". 🙂
I'm most interested in getting the antenna impedance closely matched to 50 ohms. Cuz that's one thing I CAN control. I'm still shopping for ultra low loss feed line. It appears that is where signal loss occurs. Even if the SWR isn't ideal, all the transmitted energy will eventually be radiated. Signal is lost in the feed line as the transmitted signal bounces to-and-fro between transmitter and antenna...
