It seems only one person has ever "blown up a Palstar AT4K on 160" that had it tuned properly. I use my AT4K from QRP to QRO and measuring the loss using my OHR WM-2 QRP wattmeter and K2 combo it has less than 2 miliwatts if you take the time to tweak it. I have 3 different 160m antennas and have never had a problem even with the most picky one to tune.
As with all things YMMV but at one time I did own an MFJ-989D it was a pig as far as lossy and felt like turning a rough jack when tuning. The Palstars are smooth as silk this is my second one.
