Perhaps there's a 4:1unun inside, and the designers (or the sales types, or both) either don't know the difference between an unun and a balun -- or they don't think most hams know the difference (in which case, they're right about the hams). But there is a difference. More than one small output has made ham antennas with ununs inside and mistakenly called them baluns. Many screwdriver-type mobile antennas contain ununs that the dodo-bird marketers call baluns.

In that case, it could be a reasonable match at some one frequency, but need a tuner anywhere else.

But there's still a mystery in that 30-foot-minimum feedline --
