Well technically a STA (I pronounce it “stay”) is an adapter (Single Tank Adapter) that was invented for a doubles plate to make it work with single tanks.
So in my rulebook of terms, a STA is a bolt-on bracket that is used on doubles plates to make them work with single tanks. If the plate is already a single tank plate then the term STA is a misnomer.
It should be termed a tank bracket or a stability control bracket, built-in tank stability system, or something to that effect.
Eric,
The original backplates from the late 90s and the early 00s did not have the slots for the cam bands cut into the plate. These were the true doubles plates. Consequently, an STA was needed to mount a single tank. I think only
Light Monkey still uses that old design, but they are not a major player in the BP/W market.
When the industry discovered that if they cut slots in the plate and wing to run the cam bands through, then a STA is not necessary. When they added the rods to the wings it was marketed as a "built-in STA", presumably to communicate to divers the bolt-on bracket was no longer needed. I think the industry calls it roll control now.
What your rulebook terms an STA is actually a misnomer also. If a modern plate can be used with a single tank then why is an adaptor needed? It should be termed tank bracket or any of the other names you mentioned. I assume it is still called an STA because that is what it always was called. Why change the name and confuse divers? By the way, Halcyon calls uses the term STA on their carbon fiber pro plate, so I am not the only one that uses that term. Take it up with JJ.
Speaking of terms, the use of the term "doubles plate" is misleading given that modern backplates can be used for both singles and doubles (except for Light Monkey). Also this term confused one of the participants of this thread. I never seen a modern plate marketed as a "doubles" plate it is just a backplate. I only heard the term "doubles" plate used on this thread, I understood what was meant but I have been diving since the early 90s, a newbie probably doesn't understand this term.
I understand the uniqueness of your plate is that it is designed as a singles-only plate to make single tank diving more comfortable. You can call the channel anything you want because you are the manufacturer, but I would caution you to pick a term the average diver would understand.
Have a great day and dive safe.
