Good small antenna  Time owned: more than 12 months
Bought a used then year old Butternut HF5B after i read an interresting article in the german CQ DL Ham Radiomagazin November 98 about limited space antenna installations.
The antenna was up in the air for two years and not being used anymore.
Took me some days to clean all aluminium tubes, and i performed some modifications.
1.) Replacement of the tiny alu boom with a 2 mm thick wall stainless steel tube.
2.) Replacement of all eight antenna wire with uv resistant insulation coating.
3.) Replacement of all eight heavy rusty M-shaped brackets with home made alu brackets.
4.) Replacement of the rubber seals on all six capacitors.
Took me some days to adjust the antenna at 10ft in my garden according to Butternut tuning procedure. After final installation at 35ft above ground it out performed my previus vertical antennas.The Butterfly has very good front-to-back and front-to-side action.
I recommend it for general 20/15/10 meter use,on 12 and 17 meters it works as a dipol.
The Butterfly is built as a compromise antenna,i feel it is an acceptable substitute for a full-size tribander.
