I apologize for not looking at the Cobra antenna website before
commenting previously.   In my opinion, you would be far better off
with a center fed dipole of either 88 feet total length for 10 to 80
meters, or one about twice that to include 160.  These are roughly 1/3
w/l at the lowest frequency.   they work just as well as a 1/2 w/l
dipole, provided you use ladder line, throw away any balun in the
feedline between the antenna and tuner, _and use a balanced tuner_
such as the Palstar BT1500 (or homebrew).   You can have a physically
small antenna, similar to the Cobra, but without the hassles and power
limit annoyances (it would annoy me at least) provided you use a tuner
rated at the power you wish to run.
