I wonder if this is the Alpha Delta?  I have the DX-A which mounts to the
tower and looks like an inverted Vee with one element for 80 meters about 65
feet long and the other for 40 and 160 that is 55 feet long witha  loading
coil/trap in it.  they work quite well but it is a noisy antenna compared to
receiving on a dipole.  Alpha Delta also makes a single sloper called the
DX-B which is for 160, 80 and 40 but I can't remember how long it is.

Take care all and very 73.
