Yes, you can. The GPS antenna supplied with the GPSDO module is a standard medium gain (26 dB) active GPS antenna. Most GPS antennas require 3.3 to 5 volts of DC power on the coax to power the antenna preamp and the FLEX-6000 GPSDO provide this voltage.

Then GPS antenna connector on the FLEX-6000 is an SMA type connector.

You can extend the length of the supplied RG174 coax in order to reach a place for the installation of the GPS antenna where it can receive the satellite signals.

The Tram 1655 from Walmart works well, I think it is rated at 30 db.
You do need a BNC to SMA adapter to connect to the radio. I think it was $24 delivered to my local walmart. I haven't put it outside yet as get a quick lock with it sitting inside the house on a shelf next to the radio. 73s Jim K4JAF

I am using this GPS antenna: https://www.fairradio.com/catalog.php...

through 100 feet of LMR400 and a DC-passing surge suppressor. It's mounted 10 feet above the ground with a 1/3 blocked sky to the north. Consistently locks on 10 to 12 satellites. 1.5 KW running through a different coax in the same conduit and to an HF antenna 40+ feet above the GPS antenna.

I recently bought this GPS antenna from Amazon, works very well with fast GPS lock times, and sees 10+ satellites with a very narrow view to the sky between two houses. I have it outside on top of one of my A/C units.

It has a magnet on the bottom to stick to any ferrous surface, has 26dB gain, and is meant for automotive applications, so it's weatherproof.

Can't beat the price, either!
