Naming Conventions for IGS Equipment

Hi all,
When I use NRCAN’s CSRS-PPP service, I am still receiving the same error that others have reported:

Warning: Although an antenna record was located in the RINEX file, no phase centre information could be found in the IGS/NGS file for your antenna. Estimated height should be used with caution. Ensure that both the antenna type and the RINEX header record "ANT # / TYPE " are valid.

I have attached an image of the settings that I have been using with RTKCONV, and the RINEX header - I am attempting to get an accurate position for an antenna mounted on the roof of my office, for future use as an NTRIPS Base Station. Can anyone see what I may be doing wrong?

Thanks so much!
