Does anybody know what exact frequencies are used? Are they licensed to Rockwell Collins?
These maybe?There aren't very many frequencies or base stations.
Callsigns for FCC FRN: 0004383329 (Rockwell Collins, Inc.)

Or some ARINC/ASRI ones?
Callsigns for FCC FRN: 0013756952 (Aviation Spectrum Resources Inc)

Note that the FCC data shown on RR for most HF licenses is the channel center frequency.
The suppressed carrier (USB display) frequency is 1.4 kHz lower.

On November 17, I visited the Huntington Beach (Orange County), California element of the 2015 Multi-Agency Regional Radio Interoperability Training Exercise (MARRITE). Two portable HF radio systems were deployed.

A local representative from Rockwell Collins ARINC UrgentLink was present. The transceiver deployed was provided by an UrgentLink client, the County of Los Angeles, Sheriff's Department. Unfortunately, the man-portable, battery powered station was only equipped with a handset. No internal or external speaker was present in the client's station. No connection was demonstrated during the 20 minutes I was present. I did learn that the UrgentLink system does utilize MIL-STD 188-141C ALE.

Representatives for Barrett Communications were also present nearby. They confirmed that UrgentLink uses standard ALE and mentioned that Barrett supplied equipment is utilized at points in the system. They did not specify if the Barrett radios are infrastructure stations or subscriber sets. Barrett demonstrated a non-UrgentLink trailer mounted HF system with a portable antenna. They were able to demonstrate clear reception of a NVIS station in adjacent Riverside County but the Riverside County station did not copy our transmission. They did demonstrate a a complete voice exchange with Fort Huachuca, Arizona, approximately 470 miles away.

Can you describe any antennas you saw and what heights they were at?

Both systems utilized similar coax fed, single element, wire antennas in an inverted V. The antenna heights at the center supports were approximately 8 meters; The ends of the active element were approximately 3 meters high.
