Yep. I've played with 160 M by loading up my 80-40-20 vertical which is about 40 ft tall with a capacitance load on top. Using a big loading coil I made from some scrap city sewer pipe about 8 1/2" diameter with about 20 or so turns of aluminum ground wire and alligator clip attachments to find a match with my MFJ antenna analyzer before I put power to it. No more than 100 W applied to it by me though.
