>Commscope makes a very nice CATV-grade RG6 specified for direct burial. Another good RG6 variant is Belden 1829BC. It's gel-flooded, solid copper inner, braid + foil. Works well with PPC and T&B Snap-N-Seal type connectors. I selected it for use in a DC power-passing application for a Hi-Z 8-circle array. Paul, W9AC
