Specifications

Cobleigh Hall, on the MSU campus and a remote site located twenty miles north on Rocky
Mountain Road. The Cobleigh Hall antenna was located on the roof, approximately 80 feet
above ground level. The antenna at the Rock Mountain Road site was mounted on an 8-foot
mast. The path between the locations was line of site with no blockage within the Fresnel zone.
Figure 4.1 shows a terrain map of the area with the two antenna locations labeled. The elevation
difference between the sites in combination of the antenna heights provided for Fresnal zone
clearance as shown in Figure 4.2. A photo of the remote station is shown below in Figure 4.3.
The view from the Cobleigh Hall site towards the remote site is shown in Figure 4.4. For these
tests 28 dBi sector antennas with a beam width of 4.5 degrees were used at each end. A portable
generator powered the remote site. Results are shown in Section 5.
