Jim, It has been some number of hours now and we have not heard from Wayne (likely doing New Year's eve celebration with the family), so I will attempt to answer from my recall of prior information from Wayne. First, I believe the KAT500 will have a range as great (maybe greater) than the KAT3 - so if the KAT3 handles your antenna, the KAT500 should too.
I would also like to say that the stated 10:1 SWR tuning range is not absolute, but is worst case. The matching range of any tuner is more limited at low frequencies. For instance, if the tuner can match a 10:1 SWR at 160 meters, it may be able to match a 25:1 SWR at 10 meters. Of course, that all depends on the resistive to reactive ratio too - all loads are not equal. 73, Don W3FPR On 12/31/2011 4:36 PM, Jim Bennett wrote: > An interesting question!!
