I have a 64 foot Trylon Titan Tower at 64 feet (with a 3 element Steppir)
and it's 30 metres from my home. I intend on burying the feedlines (X2
1/2" heliax and x2 RG213 coax) plus rotators cable and Steppir cable. I
was going to dig a 4" wide by 6" deep trench then just bury them. Yeah,
that's alot of work with a shovel. Any better suggestions? This is my
Labour Day weekend job (get the pun?).

That is my setup but I put large 4 inch plastic tubing in the trench
so that the innards could be easily removed, inspected and added to
without having to re dig the trench each time.
I left a heavy wire in place to make it easy to make changes over the
years. Because of the length underground and then the tower I used 7/8
heliax. I also placed a pipe into the tower concrete so I could place
the coax inside the tower if I wanted without the possibility of the
mower hitting it.
