I've been having fun and some success with a 5 band hex beam. It's only at 20 ft and 50 ft would be much better. Its SWR is less than 1.5:1 on each band 20-10m. There is an option to add 6 m for little or no cost.
It's only 2 elements so it doesn't have a lot of fwd gain (9-10 dBi) but good f/b of 20 dB. Not too expensive if you HB it.
