I'm up the tower today or real soon now to hang experimental 60M and 30M
half-wave wires on an existing balun-fed 80M half-wave slopper (sic), using
these spacers. My hope is that the wires are close enough to couple
parasitically to the slopper and radiate the way they do in EZNEC3 . . . we'll
see.
