Mag Loop Tuning Aid

Since the HF transceiver I use doesn't have an SWR meter, I went in search for a way to ensure my mag loop antenna is tuned properly without any extra equipment. So, I built this little tuning aid.

Small Transmitting Loop (Mag Loop)

From all the articles online and YouTube videos, it looks like the bees knees. I've decided to give it a try and find out exactly how good they really are.
