Correction:

In my haste (yikes!), I erred and grabbed the first 2 values for X+jY...

...so in hindsight, from the load side a series inductor or transmission
line and then shunt capacitor works easily.

But... unless you need to be better than 1.25:1, why not just use just 1
component - a shunt capacitor?

apologies,
