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.
Those HF antenna must have been quite short by the sounds of it.....make me wonder how effective there were....compared to the external long wire.....top of tail to the cock pit area.,
