> driveway to install 1/4 wave lines. BTW, the published Vf for the line is > .8. Turned out to be .73. Good point Ron. Always good to measure the cables unless it is a *reliable* manufacturer. All of the RG8X I've measured has been .7 to .75 vf. Foamed cables can range from anything over .66 up to .9 or over depending on the density of foam. 73 Tom
