Improved grounding system for mountain top radio sites
Abstract
The use of bentonite (well drillers mud) when installing vertical ground rods was described. This concept was developed to use copper tubing a lateral trench (radial type ground) that has been backfilled with layers of bentonite. In the case of mountain top sites, it is usually possible, with machinery, to obtain a trench that is 200 mm to 600 mm deep. Several of these sites are over 3460 M and are getting a backhoe and dry bentonite to these locations was discussed. In addition to the radial ground, metal oxide varisotors (MOV), bipolar zeners and coax tee's are used to complete the protective scheme.
