Our ex Pam Am and American 707's had two couplers at the tip of the tail and a LARGE RF relay that swapped between TX on #1 or #2. The coupler controller sat in the E&E next to the TR.
Interesting to read the number of 707's that had the one on the STBD wing tip.
I think we had both 618Ts and one or two had the 628T with the adapter rack to fit where the 618T was.
Our CV-990's had Collins S4's, coupler in the tail, controller next to the TR.
I don't remember our L188 having HF.
