Don't worry about feedline loss for a Beverage.  A few dB loss isn't 
going to make any difference at all.  You can worry about feedline loss 
for transmit antennas, not for receiving antennas.

Thus, as I plan for long cable runs back from my (to be installed) Beverages I am thinking I need either solid copper, solid aluminum,. or copper covered aluminum for my RG6 coax.  So the question is am I wrong in this understanding?
