Location: National Forest near, NC
Latitude: 35° 11' 59" N
Longitude: 82° 52' 19" W
Altitude: 895 m
Telescope: Two 26-m, a 12.2-m, a 4.6-m antenna, and a pair of HF LPY.
Approximate total Surface Area: 1200 m²
Coverage: 0º-360º az., 0º-90º el.
Frequency Band(s):
Currently Operating:
Current radiometers on the west 26-m telescope include the frequencies 1.4 and 1.6 GHz for HI / OH measurements, 4.829 GHz for formaldehyde detection, and 6.668 and 12.178 GHz for methanol detection. A 327-MHz receiver is in place for Pulsar timing tests. The east 26-m telescope has a 1.4 GHz radiometer, 3.4 - 4.4 GHz, and 11.7 - 12.2 GHz feeds. A modification for 327 MHz and 4.829 GHz is underway.

The 12.2-m telescope has prime focus feeds supporting 6 cm (3.3-4.4 GHz) and 3 cm (10.9-12.75 GHz), and a removable cassegrain subreflector and feed assembly is available for 6-5 cm (6.6-7.7 GHz) operation. The precision surface of the 12.2-m antenna will support planned operation at 1, 0.8, 0.7, and 0.6 cm (21.7-24.1, 36.0-36.5, 41.0 -45.0, and 48.0-49.0 GHz).

The 4.6-m antenna is configured for 21 cm (1.42 GHz), 4.829, 6.668, and 11.178 GHz reception. The antenna was part of early NASA experiments at 30GHz with the ATS (advanced technology) satellite. So higher frequencies may be added in the future.

A NASA JOVE project 17 - 30 MHz antenna system consisting of two large 7 element log periodic yagisphased for LHCP and RHCP reception feeds Jupiter and Solar flare data to the Internet.
