Appendix H. Tripod CS110 and StrikeGuard Site
Power and communication cables should be run down the equator side of the
mast and under the enclosure as shown. Wire-tie all cables into place so they
don’t move with the wind.
H.1.2 Determination of Csite
Surface mounted upward facing CS110: SN1022 with Mparallel_plate = 88.31.
CM10 Tripod Mounted StrikeGuard and CS110: SN1023 with Mparallel_plate =
81.77.
Each CS110 recorded one minute averages of 1 second measurements of electric
field data for the same one hour time period from 3 AM to 4 AM on August 11,
2005. The data from both units is plotted in Figure H-6. A best-fit line was
computed. The linear regression yields a Csite = 0.108 for the Tripod CS110 and
StrikeGuard Site.
