85-1 Antenna

The 85 foot antenna (one of two 85 footers) is at the Old Rosman NASA site in North Carolina.
This will be the Pisgah Astronomical Research Institute (PARI), January 1999.

Notice L Band Choke and Feed on mounting plate.

15ft Dish at PARI with RAS Choke and Feedhorn

Rack Mounted Ultra Cyber

The Ultra Cyber is shown as it is recording data from the 85-1 antenna.


The Ultra Cyber is a "SETI Capable" radio telescope receiver.
