Installing an entirely new transponder is going to require a certification anyway.

If the static system is NOT opened, I do not believe 91.413 requires a static system check for transponder install.  Not even sure it's required if the new transponder, within the previous 24 calendar months, "...has been tested and inspected and found to comply with appendix F of part 43 of this chapter." (91.413b).  I would think a brand new, certified, transponder would meet that requirement.  But, I could be wrong.  Hopefully, one of our avionics shop members can chime in.

In any case, static system test is NOT required when installing a Sky/TailBeacon
