On my 75 meter dipole I have a low swr on most of the band. But when I go to the lower part of the band I need to tune it. I was thinking of putting a switch in my MFJ tuner to bypass it for the upper part of the band, and use the tuner for the lower part of it. I see in most tuners there are aluminum wires in it. Is there a reason for this?
What I am asking is. Has any one tried this and does it work?
