Hi Allison, these 1:49 transformers are just conventional transformers. Would you think that a 1:4 and a 1:9 current (not the voltage ones) transmission line transformers in series to get a ratio 1:36 would be too lossy as I think or may be used? In that case the transmission line of the 1:9 transformer is just 150 ohm which is theoretically too low.

The feature that is desired of ferrties and iron power for transformers is coupling as
close as possible to 1.? Very hard to get that with air cores.
However by building them as transmission line transformers (Guanella)
its possible to do that with excellent coupling factors.
