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.
