I am primarily interested in SW listening, not amateur, and really 16
- 160 meters. Would you recommend Type 61 for this application?

With SWL, the type 43 would work better at 160m and the 61 better at
17.48–17.90 MHz and above. But, the type 43 would work well on MW,
which I am assuming is of interest to you also. Antenna type,
inductance/performance you find necessary in rejection of CM, size of
the core, number of turns, etc. all factor in, also. Mainly, I am
tossing this stuff our for "nit pickers" like me ...

You could get by with either material ... one will favor the top end,
one the bottom ... but you can use either. Some might see the
difference between performance of the two as "splitting hairs." I just
go to extremes for fractions of s-unit, or db. LOL
