hi walter,
ok, i bought 2 gps receivers and two antenna's off ebay from the same seller.
The antenna's were separate sale from the receiver but it shows the antenna plugged into a receiver that looks like the one i got.


The antenna is a Rockwell Jupiter TU30 GPS module 's 27db GPS antenna and my receiver is a Rockwell GPS TU00-D200-401

Datasheet for the antenna is http://www.inpaq.com.tw/en/RF_Antenn...ed20100224.pdf

I hope that helps. Thanks
