Topband: Beverage feedline suggestion

[David J Rodman MD]

My beverage antenna to Europe was cut down by new property owner.  The 
best replacement configuration on my OWN property is 580' at 40 
degrees.  The only problem is the coax feed line is approx 600' from my 
beverage coax switch and another 200' to the station.  If the antenna is 
to be used on 160 and 80m, what feedline is suggested to maximize signal 
and minimize cost.  Right now the antenna is fed with "mini" RG59 and 
the antenna is at least 1 S unit less noise than my other two antennas.  
I presume the quietness is loss of signal from the feed line length.  I 
haven't matched the antenna to the feed transformer yet, but it is hard 
to imagine that would be 6-10dB loss.  Thanks for opinions.  Dave.
