SPK6618H not on opus antenna menu?

The HFX6618 antenna looks like a suitable alternative. It utilizes an older version of the same 6618 base element.

Antenna #/Type for SPK6618H antenna?

Originally, I used the Sparkfun TOP106 antenna as part of my PPP setup and I specified NONE/SFETOP106 as the Antenna #/Type in the rtkconv options when converting from UBX to OBS file format. This seemed to work well when I submitted the OBS file to CSRS-PPP. Now I’ve started using the SPK6618H GPS antenna and I specified NONE/SPK6618H as the Antenna #/Type and got this response from CSRS-PPP: 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. What should I specify as the Antenna #/Type when using the SPK6618H antenna?
