BT-147 GPS L1/L2 antenna equivalent for Trimble RTX PPP website?

Hi All

I have several Sparkfun BT-147 antennas now in use with Sparkfun ublox F9P boards. They are working well together with my Unavco NTRIP account and ublox u-center software. I would like to submit the .obs file I have created from the u-center .ubx file data to the Trimble RTX website for PPP positioning. The first thing the site asks for is to select the antenna I am using. I have not found the specific Sparkfun BT-147 listed yet… but there are similar antennas as selections. I am willing to lie. Do you have an equivalent suggestion? The Canadians are easy. The NRC CSRS PPP web app doesn’t care what antenna I am using and I am waiting for their response now. Has anyone tried this yet? Great products!

Don’t think it matters too much but whatever you use, use that selection every time to keep your data consistent.
