There are several antenna analyzers on the market:
While these are good products, there missing one thing–a computer interface. If the MFJ or my Autek analyzer should have either a built-in computer or a computer interface or both. With that interface, you could make automatically tuning antennas. For example, if you were using a Slinky antenna, you could make a device that would allow the analyzer or computer to control how many windings were in the active coil. For a base-loaded antenna, it could automatically adjust the tuning components at the antenna’s base.
For non-tunable antennas, it could automatically plot frequency vs. SWR curves. It could also store this data and you could plot how an antenna system’s SWR changes over time and in conjunction with various weather conditions.
Wouldn’t that be cool??
