Gang,

This is my annual request that there is a simpler way to feed a tower.  Tom N4KG wrote an excellent article on his reverse feed system in the April 1994 QST. With Tom's system using elevated radials (either loaded or full length) you feed the coax to a radial and the shield to the tower.  We used a MFJ 259 to find a place to attach the radials for a match on the tower.  Tom also had an excellent section of calculating top load to get electrical length. If you don't have the actual QST you can down load the article.
Cebik contributed an article on reverse feed of towers and showed that there little ground loss that W8JI and others predicted.  

We did two towers one 60 feet and one 90 feet and the results were very good with great DX.  Tom ran several towers and most low band DXers know his results.  Sadly Tom became a SK last year. Best DX was Zone 17 on CW and Zone 25 UA0 from GA on SSB.
