I have a Force12 Sigma80 vertical dipole and am wondering about the possibility of using it on 160. What about removing the coils and feeding it with 450 ohm twin lead to a TenTec 238 tuner? Think this would work? Would adding a second set (or more) of top and bottom T bars be worthwhile? Tnx for any suggestions. 73, Doc K7SO Espanola, NM
