Anyone Recognise this GPS Antenna?

 

Recently I was given an unused GPS antenna and a Rockwell Jupiter GPS receiver.? He thought they were purchased from QRP-Labs, but wasn't sure. Given the age of the Jupiter GPS receiver, the doccumentation I found is dated 1998, I'm not sure if this is possible.? I'll attach a photo of both.
?
I'm wondering if anyone recognizes the antenna. It is a shallow black plastic dome with a threaded mounting shaft on the underneath and a fair length of coax terminated in an SMA.? Is it passive or active? Any idea where I might find the specifications?

Given the SMA connector I'd say it is simply an antenna, so passive.
A receiver from 1998 is unlikely to be considered a good one given what is available nowadays. It will be slow and GPS only so not GNSS capable. Others may be able to correct me on this.

Jupiter GPS receivers are popular still for GPS locked oscillators as they have a 10kHz output

They normally sell quickly on eBay if you don't intend to use it yourself for this.
