That Sked 40 is too heavy and unnecessary. Use 4" dia. ten foot lengths
drain pipe with pre-cut round holes in it on one side. Light, cheap,
swagged on one end, expanded fit on other end, glue or no glue, has 45
degree bends available, is usually big enuf dia., and comes with my
personal stamp of approval. DO NOT SEAL UP underground cable runs.
Because u can not seal up underground cable runs. But, u engineer types,
go ahead and seal them up then dig them up a year later and pour the water
(or ice) out. Water will get into (or is already in) virtually anything a
ham will make or have. Get used to it! Provide escape for moisture, give
up on "sealing." Leave that to NASA and others with really big bucks. de
