[TowerTalk] Measuring RF ground characteristics

[Artek Manuals]

Rick

I have over 20' depth of pure sand, drains like a sieve literally. It 
can rain here for days and I have no standing water. Since I grew up in 
this neighbor hood I vaguely recall the well drillers going down more 
than 60' before they began to encounter ( limestone) bed rock.
