Then those aren't what we call "real hams". I don't think I know of an AM Radio Operator that would be caught *dead* running a store-bought dipole antenna. Them folks are no more than an appliance operator.
I get a chuckle when someone tells me they are using a "homebrew dipole". I assume, by default, that when someone puts up a dipole, it is homebrew, especially within the AM community.
