Appendix G. CS110 2 Meter CM10 Tripod Site

FIGURE G-3. Earth grounding

Stake the tripod to the ground and/or weigh it down with sand bags.

Determination of Csite

Surface mounted upward facing CS110: SN1022 with Mparallel_plate = 87.6

Tripod with CS110 only: SN1023 with Mparallel_plate = 81.77

Each CS110 recorded one minute averages of 1 second measurements of electric
field data for the same 2200 to 2300 hour time period on October 2, 2005. The
data from both units is plotted in Figure G-4. A best-fit line was computed. The
linear regression yields a Csite = 0.105 for the Tripod CS110 Only Site.
