Topband: 50 ohm direct burial coax cable

[N5PA]

I agree, the LMR-400DB and LMR-600DB is the way to go.  Great loss numbers,
higher velocity, and better high SWR handling characteristics.  I use both
with great results.  These new 43 foot verticals will need LMR-600DB if you
are running legal power to handle the high currents, unless you are running
an automated tuner at the base of it.

Bury Flex is good cable, however, in comparison to LMR400, its velocity
factor is 10 to 15% lower.
This means that its insertion loss will be 10 to 15% higher.  The VF also
isn't as well controlled in Bury Flex, in case you are making phasing lines.
I use both kinds, in the appropriate applications.
