I already have the MFJ-259D ANT Analyzer, and I can vow that it's very useful for, not just the 222MHz Amateur Band, but the Medium Wave Broadcast Band, for looking at the input of Part 15 AM Carrier-Current Couplers and Part 15 3-meter compliant radiator antennas. So, at the price that is being asked for on that MFJ-259C, well worth it, for a useful piece of measuring gear.
