There are no serious losses with that kind of choke balun. It's only the 
  loss of the extra length of coax that makes up the coil, or maybe a 
few watts to make the ferrite beads get slightly warm (if the beads get 
hot,   they're the wrong type of ferrite, and/or not enough beads).

Choke baluns are very tolerant of high SWR. The ones that aren't are the 
transformer types... so don't use those.
