Topband: Beverage Front to Back Non-exsistant

At what frequency Pete? At the upper end of the BC band, you 
should still see F/B (it will be 1 wl long electrically or longer) but at 
the bottom of the BC band the Beverage will only be 1/3 wl long 
electrically! Don't expect any great directivity in that case.

I spot check my Beverages at the upper end of the AM band every 
day. I have a list of stations with F/B ratios written down. When a 
termination opens up or an antenna falls...I know immediately 
which one it is. I don't see why your system should behave any 
differently.
