[TowerTalk] New (?) idea for protecting underground feed

[pramey@smtplink.ram.com]

     I think that you have a good idea IF you never need/plan to ever 
     replace the coax runs.  If you are taking the time to protect it you 
     need to also have a plan to replace or upgrade the runs if & when 
     needed.  How long is the useful of the tower? Do you plan to move the 
     tower or your location in a few years?
     
     Have a great day and thanks for you imput that you sent to me on your 
     FK-2568.

Now that the #25 foldover is (finally) on it's way back up, 
I thought of an inexpensive method of protecting my 
underground feedline that I don't recall having seen 
described.  Here's what I might try, unless I get some real 
negative feedback:
     
I'll pick up appropriate lengths of 5/8 inch i.d. garden 
hose.  Rubber or vinyl, depending on the state of my 
pocketbook.  My LMR400U will slide nicely through the hose 
(sans connectors), and the hose will be buried in a shallow 
trench.  I some advantages in that there will not be a lot 
of air space between the coax and hose (maybe 1/2 inch hose 
will provide an optimum fit) to collect moisture, and the 
hose comes with built-in waterproof connectors, with 
adapters readily available and easy to mount on entry 
panels or switchboxes.  The hose is easily extensible if 
needed with more hose and connectors.
     
Since the LMR400U is not rated for direct burial, I'm 
hoping this will provide sufficient protection without my 
running into the underground pipe filled with condensed 
moisture problem, with the water eventually making it's way 
through the coax jacket.
     
Any comments?
