If I recall the BL1 was designed for a 200 ohm load. Will
it still do a 4:1 conversion if the load is 1000 or 2000 ohms?
Yes, although the higher the impedance, the more the balun's own strays
will come into play. (Note also that at QRP levels, a large balun such
as the BL1 should have negligible heating loss over a very wide
impedance range.)
I'd suggest experimenting ahead of time with the tuner, balun, and
typical antennas.
