When it comes to 100 watts being barely adequate for 160 as some have suggested, could it be the modern scenario as explained to me by the folks at DX Engineering at Dayton a couple years ago? I have had a 43 foot vertical for over 40 years, and old commercial model made in the 1930's. I have a good counterpoise underneath it along with a home made remote tuner at the base. When I inquired about the sudden popularity of the 43ft vertical, and the fact no mention was made about matching or just the use of a 'special' balun at the base, I was enlightened by the DXE guy. His experience was that a whole crop of hams today, don't care what is going on from the rigs output to the antenna as long as their antenna tuner will match the load. If they can hear something or work one or two, they are apparently happy. A 20:1 SWR on the feedline is inconsequential to them as long as their meter says 1:1 and the power out is 100 watts to the tuner. So, your 100
watts to a well fed antenna may not be the Achilles Heel you think it is, it very well could be the other ends problem. This applies to all the bands also, where antenna bragging comments along the lines of "I work everything I hear", really means they may not be hearing much.
