Ken...

I have decent results with RG-6/U.

It's cheap, it has decent attenuation figures at 144 MHz, and can be bought at Home Depot.

And the /U rating means it can be buried.

I'm sure some will differ with my way of thinking, but I have a flat 1:1 match on my eggbeaters...and couldn't be happier. (My FT-817ND is happy, too)
