FYI, Antcom and AeroAntenna are two manufacturers of high-quality American-made GPS / GNSS antennas. Antcom's datasheets are confusing to read, and AeroAntenna hides theirs behind a customer-login barrier, so most of eBay doesn't know exactly what they are. This means that good antennas are often available cheap.
For example, any AeroAntenna whose part number starts with "AT2775" is a dual-frequency L1/L2 GPS antenna. AT2775-42 is a near-survey-grade antenna, and one of them is available right now (item 263500294711) at a starting bid of $20, after expiring yesterday with no bids at $25. Several other AT2775 antennas are on eBay for under $200. Any of these would be excellent for time-nut purposes. IMHO, Glonass coverage is not useful for precision timing. If you don't have a good enough antenna installation to get continuous GPS coverage, you're not really doing precision timing. If you are getting continuous GPS coverage, Glonass doesn't add anything. Disclaimer: I have no relationship to either company mentioned, other than previously being a satisfied customer of both companies. I have no connection to any sales currently listed on eBay.
