[Heathkit] How do I lay coaxial cable underground?

[David C. Hallam]

Buried plastic electrical pipe about 1" size works well for underground 
runs.  At the entry and exit points you put an 90 degree elbow and a "U" 
above ground fabricated from the pipe to prevent water egress.  That's 
what I plan to do for my vertical.
