just wondering.... can I take a 40M delta loop and add an 80M dipole to it?
Will there be interaction? SWR problems?

Why not just increase the size of your loop to make it an 80 meter loop?? That
should cover 40m, at least thats what I've read...I'm in the process of
building my 80 meter loop which will hopefully work 10-80...Good luck..
