Topband: 1000 feet 5/8" hardline or 600ohm True Ladder line.

You are correct, Rick.  I meant 0.2 dB.  Brain not too well in gear this AM.

Thanks for the correction, so no one is mislead.

0.2% is only 0.01 dB, that can't be right.  Maybe
you meant 0.2 dB.

The ARRL Antenna Handbook shows about 0.4 dB for 420
feet of 75 ohm 1/2 inch hardline.  Paralleling two
runs of line does not decrease the insertion loss.
