The Ten Tec tuners have already been mentioned by Jim, K9YC. I've found that the old Dentron MT-3000As will tune almost anything. I have a pair of them that I use on a regular basis with a long wire and pair of 65' almost vertical wires on the low bands, 160 up to 40. They work very well and seem to hold there value based on asking prices I see on various sites. These would be a good choice for someone looking for an "interim" tuner while waiting for the KAT500. The MT-3000A uses a tapped inductor while another model has a roller inductor. (MT-3000RA may be the model number) I tried a Palstar AT1500CV a few years ago and it would not tune my antenna on 160. I put the Dentron on it and it tuned right up. I plan on getting the KAT500 when Wayne says it's ready for prime time. Until then, I'll wait and leave the Dentrons set for the low bands.
