[TowerTalk] Routing cables under buried radials

[Gene Smar]

 Ignacy:
     I'd just install a conduit from the present tower to any future one through the existing radial field.  As an alternative, I'd install the conduit through the existing radial field up to a buried pull box past the radials.  I'd finish the conduit run from the pull box to the new tower once the tower has been installed.  Then I'd replace the radial wires with new, and install the additional radials you mentioned in your email.  Reusing or soldering the existing radials would be too much work for my taste.

     Good luck.

Subject: [TowerTalk] Routing cables under buried radials

I have a 100 ft tower that is surrounded by 36 100 ft radials and 4 x 20 50
radials. Coax and rotor cable are buried. The area is planted with grass.

I would like to add more radials but a question is what to do if additional
cables are needed past the radial field, e.g., for additional towers.

Here are a few options.

1. Try to put a 4 inch PVC pipe below the radials. Lots of work.

2. Remove or cut radials, bury a PVC pipe and then solder the radials. Less
work but soldering back critical

3. Just put cables on top. After 1-2 years they will migrate underground.
Not sure if a riding mower, or a truck (to install a new tower) can do
damage. Or enough damage creating intermittents, e.g.,  with OM8000
amplifiers (if purchased).

4. Bury 2-3 cables under the radials and use Green Heron stuff for WiFi
switching, including remote rotor controllers.

5. Route additional cables around the radial field with better coax to
compensate for extra length.

6. ???
