The request was in response to a statement that the KAT-500 was not required if an all band antenna was used. The challenge was to name an antenna that will give full coverage WITHOUT TUNER making the KAT-500 superfluous. Of course, full coverage of 20 is 14.0 to 14.35 and 80 and 160 are included. Alpha-Delta makes nice products, but achieving full coverage on 160, 80, 20 and 10 is elusive. Maybe you only work CW and don't care about the phone band or 10 meter FM, but if so, you don't require full coverage. Even 40 requires you to accept a pretty high SWR at the ends to cover the whole 40 meter band. LPs can be good for broad banding, but even the RCA LPs that I saw on Guam with the rotors that weighed about a ton only covered 7.0 MHz and up.

Full band coverage on 40/20/15/10, plus about 100kHz on 75/80, partial-full coverage on 17m although it isn't cut for it, and some 6m as well. Full coverage 80m-6m with tuner...and even 160m, but the efficiency has to be terrible. And easily handles 500w+ 73 Dave On Wed, Jul 13, 2011 at 12:26 PM, Ken - K0PP <[email protected]> wrote: > > Hi Cookie, > > My Alpha-Delta pretty much meets the no-tuner-needed > requirement.
