My vote: 40 meter length off-center fed dipole or vee, 69' total length, fed
22' from end with 4:1 balun, large coax choke in attic where coax enters. Mine
is veed both horizontally and vertically, has 41 degree takeoff angle on 20
meters, tunes all bands from 40 through 10, most tuners in radios will work,
1.2:1 SWR on 20 meters, about 6:1 on 15, worst band for SWR. Computer (EZNEC)
designed for low takeoff angle on 20 meters, antenna only 25' high. Better than
80 meter length dipole at 40' on 20 meters, at that height 160-20 meter radiation
is straight up. Hope this is of interest.
