[TowerTalk] How to run my 400' feedlines?

[john at kk9a.com]

I had a 350' run at my previous station and I direct buried 1 5/8 hardline 
without any problems.

I am in the process of moving my tower, which requires me to re-cable the
feedlines.  The new runs will be roughly 400', and I think I am going to use
LDF5-50A Heliax.

The question is how to run the cable.  The options are:

1) Direct burial in a ~18" deep trench.  I don't think that running conduit
is going to be an option.  Is Heliax "rated" for direct burial?  Does it
matter?

2) Run the cables through the trees at about 8' up in the air.  This is
obviously not as good aesthetically, and I've had some problems with current
on the shield of previous "hung in the air" feedlines - but it may be the
only option if direct burial is out...

Thoughts, suggestions, comments?
