Mystery Antenna: Good for 1090Mhz?

I have a ‘proper’ antenna tuned for 1090Mhz from eBay for my receiver. The other day, I noticed an unusual antenna with a nice long cable in our local thrift shop. The plug is larger than the MCX I am used to. Can anyone help me to identify the purpose of this antenna, and is so doing help to determine if it would be at all helpful for ADSB reception? Picture should be attached…[nope, the ‘img’ tag doesn’t seem to work for me, so I will use a ‘url’ tag instead):

does it have any numbers or codes on it

could yo do another picture with a ruler alongside?

To me it looks like a boat GPS antenna.

It is a Mobilespec MSTRSAT mobile, mirror mount, satellite radio (XM/Sirius) antenna. 2320 - 2345 MHz.

Cut the current antenna off the top, and you have a nice base for your ADS-B antenna :slight_smile:

Thanks! You are correct! Another fellow on Reddit also was able to identify :slight_smile:

Yep, I seriously thought about salvaging the antenna into something more useful for myself, but (for now) decided to return it back to the thrift store in case someone wants to buy/use it for its intended purpose :slight_smile:
