[50mhz] 6 meter ant

[Chris Boone]

I have done a SWR chart of a DB212-3 cut for 52MHz...it covered the entire
band below 2:1 (but right at the edge!).....SWR was of course better in the
FM portion.....Can you make a 6m antenna cover the entire band? Yes, but its
not easy nor is it really needed......
