Sorry for the delay...
I decided not to use LA5HAH calculator but my own method and came up with these figures...
5200pF in parallel with 1.4uH equals a resonant frequency of 1.865Mhz...
Each 11N90 has 300pF capacitance which totals 1200pF...
5200-1200=4000pF for the external capacitor....
The Q is very low so the bandwidth will be quite large.
The inductor will also be large but manageable and will get hot so hot that you may have to bolt it down...
Have you decided on the output balun construction whether or not to use ferrite beads or a toroidal core...
You could use twisted wire...
