[TowerTalk] Power ground

Hi,

Additional radials will always help. No detriment to this. However using
brazed water pipes is not recommended. The brazed connections represent a
seriously weak electrical joint and may fail prematurely under thermal
stress of high currents.

Subject: [TowerTalk] Power ground

Hi, all concerned:

My building-entry power ground (rod), here in Cincinnati is, well, in
not-so-good condition, after years in service.

The line comes in above grade to a corner of the building, through trees,
from a pole 75 feet away at the county roadway.

When the rod is replaced, would there be an additional lightning-strike
safety benefit to adding "some number" of short radials to it?

What are the *technical* pros and cons of burying the line?

Can physically-separated grounds be tied together with buried copper water
pipe sections brazed together?

TIA & 73,

Dave, N3HE
