[Antennas] Dipole "Multi-band" pairs?

[solo22 at sbcglobal.net]

If you need all these bands,  why not just put up one inverted vee 
dipole about 35 feet each side of
feedpoint, feed it with 450 ohm window line to a good tuner like a 
Johnson matchbox.  Works great here for me.  Just an idea.  Merry 
Christmas from Ron K6ZL
