The 17th edition of The Radio Handbook, by Bill Orr, W6SAI, on page 451
describes a 2-band (160 and 80m or 80 and 40m) antenna called a "Multee."
The dimensions for the 160-80m version are:
Vertical element is 52 ft.
Horizontal (top loading) element is 70 ft.
Both horizontal and vertical elements are made from 300 Ohm TV-type
wire.
6 (or more) radials, each 50 ft.
It is fed with 50 Ohm coax directly (no matching network required for
dual-band operation).
These dimensions exceed those you specify, but come close. If you'd like
further details, please supply your address off reflector and I will mail
you a copy of the article.
