[Antennas] Suggestions Hardline Feedline Run

[Richard Freitas]

Hi Ed,
   
  I would think that landscape timbers would make one heck of a speedbump and I would be worried about them shifting over time due to the consistent traffic across them and causing damage to the feedline.  For quite some time, utilities that are underground have at least 18" of coverage and some, like electrical primary lines and telephone feeds are close to 36" deep.  If you were planning on using landscape timbers, it tells me that you don't have a problem with the feedline being close to the surface near the road area.  I would run the feedline through rigid steel electrical conduit (very similar to pipe) and bury it just below grade so there is a light covering of road surface over it.  Basically, you just want to "scratch" it into the surface.  It seems that you could dig 15' or 20' by hand (carefully) if you think there may be something else that close to the surface.

  Hello all K5OF, Ed, here in NC, Recent new subscriber and past subscriber from few years ago.I relocated and I am in the process of building a new home and station here in NC. New station will require hard-line feedline run to go across 15ft to 20ft dirt/gravel roadway/driveway to shack. This roadway has electrical and telephone line feeds to my property and a easement right of way to other property owners on adjacent land right down the middle of said roadway.So burial is out of the question to cross roadway or running through pipe or culvert due to unknown depth of electrical or telephone and possible damage to mine or my neighbors feeds. (buried more than 30 years ago!) Looking for any ideas other than what I propose here to get feedlines to shack. My idea was to place large landscape timbers similar to RR ties across road laying parallel to each other across road with a wide enough space to accommodate feedlines required and eventually covered with earth to form a
 sort of "speed bump" like effect for lack of better term and visual to get feedlines to the shack. Lining the trough between the timbers with sand and/or small rock for drainage and the feedline laid on top of the sand or rock eventually covered with earth. This would permit any maintenance or replacement of feedlines to be accomplished without a lot of effort. This area is the only area of all the feedline run where I have a problem. Feedlines will be laying on ground or supported slightly above ground through woods for the rest of the run approx. 300-400 ft of feedline run. Sorry for long post but I felt being as descriptive as possible might save for repeats or misunderstandings Any and all ideas would be appreciated. Thanks, Ed
