Hey all, I happened upon this the other day, and thought I would share it with you. It is a RF Transmission Line Loss Calculator. very useful for those of you who will be stringing antennas this spring. The address is:http://www.owenduffy.com.au/electronics/tl/tllc.php I am also placing it on the KY Amateur Site Links Page for future reference. 73, Pat, KD4PWL
