RE: [WISPA] Tower hole size

2007-07-25 Thread Kenneth M. Chipps PhD
There is no rule of thumb. Contact the manufacturer as it depends on the
tower and the soil type where the tower will go. The foundation plan makes
certain assumptions about the soil. If your soil does not match these
assumptions, then the foundation will need to be altered. Usually this means
a bigger hole. There are geologist/soil engineers who do this.

Anyone know how big the hole should be for a self-supporting tower? Is
there a guide or rule of thumb? Thanks! -RickG

Different systems. They also do not install expensive electronic devices in
those buildings at the end of the cable runs.

I agree that fiber and wireless would circumvent the issue entirely.

The telco and cableco run copper from building to building.

Do not connect buildings with copper cable, unless they are bonded to the
same single point ground system.. This is what wireless and fiber are for.

What are those of you that are connecting different buildings together with
cat 5\6 cable doing WRT grounding?  Aren't all grounding systems with
anything conductive linking them supposed to be bonded together so that the
equipment doesn't become the path to ground?  Is this as simple as placing
surge protectors on both sides or is it more complicated such as running
some 4 gauge copper alongside the cable?

Same with an RG-6 cable.
