[HamWAN PSDR] KU7M testing results - Newcastle Golf Course

Fri Mar 7 14:23:10 PST 2014

I was using the 'standard' node dish antenna.

Per the linked website:

1st Fresnel Zone Radius: 49 ft at 5.03 miles (15m at 8.1Km)
60% no obstacle radius: 39 ft (12m)  Earth Height(mid): 16.87ft (5.14m)

The link distance is 16.2m

Thanks
Kenny
