The Dynasphere is prepared on the roof -
upper termination and ERICORE are attached, finial is
screwed into place and FRP mast fitted
|
The Dynasphere is elevated into position
and installed by securing the insulated FRP mast alongside
the antenna support mast using U bolts |
Upper installation complete |
ERICORE down conductor cable routed to the
ground using the most direct path. Note the smooth curves
to reduce inductance. |

Trenching to ground rod system |
Preparation of the ERICORE downconductor
cable to effect the lower termination |
Outer copper sheath and inner copper
conductor are exposed. HV dielectric is removed and
metalic conductors twisted together |
A metal sleeve is inserted over the copper
sheath and inner copper current carrying conductors |
 |
 |
 |
 |
|
The sleeve is inserted into the graphite
mold and the mold is placed over the ground rod |
CADWELD exothermic weld completed |
Apply mastic tape so as to cover joint and
prevent water egress up the cable sheath through capillary
action |
The Lightning Event Counter (LEC) is
secured to the ERICORE down conductor |
