I have a used Mosley TA33M up 45 feet and it works the world with good directional on all 3 bands. In my opinion forward gain is the most important over side rejection and F/B. These antennas are known the world over as good performers. If you buy a used one, take the traps apart and look at the coil forms for being broken on an old antenna as the only thing to watch for. They are built heavy duty and ice loads in cold temps can break aged coil forms. Don't worry about SWR over any bandwidth. It is low enough out to the edges not to make power loss a concern. The diameter of the elements help broaden the match. The co. does not actively advertise much and I think the bulk of their activity is making antennas/ hardware for commercial and military.
