[TowerTalk] Buring Bury-Flex

[john at kk9a.com]

According to the last paragraph on the RF Parts site
http://www.rfparts.com/ldf4-50a.html

"All HELIAX coaxial cables are jacketed for direct burial or
for corrosive environmental conditions. Standard jacketing
material is weather-resistant polyethylene suitable for use
in extreme climates."

I've never run Heliax and its variants in the ground. Are they rated this
way by the manufacturers? I'm looking at running either 1/2" or 5/8" foam
lines in the ground. I'm fine with direct burial as long as the cable is
rated for it.

I direct bury Andrew Heliax.  The PVC coating is very tough and the solid
copper shield should not allow moisture ingress if the coating becomes
nicked. If you shop around you can purchase new LDF4 for a good price,
less than Bury-Flex plus the PVC tubing.  It has significantly less loss
and installation will be easier. There is no worrying about watertight
glue joints or PVC drain holes. If the cable is in an area where you might
dig, you can put something over the top for protection.
