[TowerTalk] from towers to shack

[john at kk9a.com]

I am not sure what coax you use, I use Heliax buried with no pipe.  I only
use a PVC pipe for rotator and relay control cables.  While it is more
work to bury cables, especially in hard soil, I think that it does look
nicer.  There is probably no electrical reason to bury them if your
tower(s) and entrance panel are properly installed.

Hello



I'm about to review coaxials and control lines going from the towers to the
shack.

Actually I have below ground plastic pipes 100 mm (4 inches) so from tower
to shack they go underground. The last coaxial had to put on the land
because is not passing through the pipe.

Now I'm thinking about doing the same, underground, but a larger pipe, or
other option might be to put the pipe OVER the ground at a height of
1.50-1.90 m (60-75 inches) so I can walk under the pipe or at a height of
0.40 meters (16 inches) to pass over the pipe and the grass can be cut
without problems.



my question is about which is TECHNICALLY the best option, if there is a
technical benefit or about RFI to put them under ground. If there's no
advantage, is much easier to manage the cables OVER the ground



Any feedback is appreciated



Thanks in advance,



73,
