Fishers Island Mile Range

The Mile Range consists of two antenna deployment sites located exactly one mile apart; the curvature of the island provides a natural one-mile range over seawater between these two sites. The facility is used for measurement of antenna performance over the MF, HF, and VHF bands. The transmit site consists of a 50 ft. diameter seawater pool attached to buried ground radials that extend over 100 ft. radially outward. The antenna under test is mounted in the pool. A shielded underground laboratory, located beneath the pool, serves as the control room for the range and also houses an azimuth positioner and hydraulic lift mast. The receive site consists of an instrumented van and receive equipment that communicates with the transmit site via a wireless data link.
