I thought you might include this information in your vast archive of GPS

Jon,

Below is the response I received from the NGS guys regarding the test of the
TSA-100 antenna.  The data from the test is preceded by a key for reading
it.

Dr. Senior,

Below are the calibration numbers for the TSA-100 antenna. About a year ago
we had a chance to test one as it was enroute to England. However, we have
not received any other TSA-100s to corroborate the results from the first
one.

If USNO happened to purchase more than one, we would appreciate the 
opportunity to test any not presently on-line. It should not take more than
a week to do so.

The ARP is the base of the antenna.

Best Regards,
