Topband: Radials on ground v FCP

[CUTTER DAVID]

Rob

I recall a discussion on here some years ago which proposed that, whilst being an amazing antenna for top band, if you could achieve it, the broadcast model was not necessarily the best use of resources for amateur purposes, on the basis that broadcasters are mainly interested in ground wave to cover a defined relatively short range service area, whereas amateurs a more interested in dx.  

I don't recall how that discussion ended, but for purposes of saving wire, at least, the K2AV folded counterpoise (FCP) must be about as good as anyone could attain.  How it performs against that broadcast model would be of interest.
