I am with Doc also, "why" do it? If you are planning on doing it because you will be using it on a band other than 11 meters - then I guess it would be ok. But for 11 meters, I don't see any benefit in doing it. Gosh - of all the people that I have talked to in 39 yrs that used beams, I would say that probably 97% of them used a stock beam with a Gamma and they worked more country's and islands then I will ever work. Just about everyone out there runs lots of power anyway (except me) so what advantage would one have by going to "hairpin"?
