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.
