I've got about a 70 foot +/- run of RG-8X that I use to feed my 40
meter dipole. I also use the same feedline and dipole through an
MFJ-949E tuner to operate on 30 meters with. Out of curiosity can
someone tell me about how much a a signal loss I've got compared to
having an antenna that's actually cut for 30 meters ?

Thanks in advance.
