I had an old Hi Gain TH-4 (2 elements 20m/15/10m, 1 element 10m, and 1 element 15m/20m) laying around... it was not worth fixing as it was just falling apart... I stole some parts off it to add 6m to my triband yagi (old Wilson SY-33) (built 3 6m 1/2 wave elements)
It has 4 traps for 10m and 6 traps for 15m
However the boom is in good shape and I was thinking about building a 17m/12m dual band 2 element yagi
I was thinking that MAYBE I could just use the 15m traps
looking kind of like this
17m 12m 12m 17m
------15m trap---------feed point---------15m trap------
Question would a 15m trap work or would this be a problem?
