Stuart, In the old Ham Radio Magazine, a 1988/89 issue there is a very simple circuit called a PHASOMETER by the author. It uses as zero center meter (although you could set up LEDs to perform the same way) to determine which side of resonance your antenna on.
The specific purpose for this unit was for determining which way to skew your inductor to tune your mobile antenna. The author was going to incorporate it with an earlier motor driven inductor. He also suggested it as a tool for vision impaired folks. I thought that it would be useful for increasing bandwidth tuning for a low band antenna. If you're interested, I can find the article when I am back home sunday and make a copy. I have the article for the mobile tuner as well.
