Percent smaller for the Inverted Vee

The picture above is a diagram of the old standby CLASSIC antennas....the Dipole and the Inverted Vee.

They are shown superimposed on each other in the drawing and without the feed line for clarity. Feed line (usually 50 ohms) is connected at feedpoints, center conductor to one side, the shield to the other side of antenna. The blue  line in the drawing is the example of a dipole. The colored line is the inverted vee configuration. The inverted vee is is just a lazy dipole that can't hold it's arms up and is about 4 to 5% shorter on each half! Both antennas can be constructed just about anywhere using any type of wire you may have and can be used with 50-75 ohm coax or open wire ladder line and a tuner. When fed with open wire type feed, it becomes a multiband antenna using a tuner. The use of an rf choke is recommended when using coax feed!

You could use the calculator to build a 75 meter dipole and then calculate an inverted vee for other bands suspended under it from the same support and feed both with the same line to xmtr.
A little experimentation may be required for adjustment of the SWR, tuning the 75 meter dipole first for lowest SWR and then the inverted Vee.
