	WRONG.  An inverted vee is perdominantly 
	horizontally polarized. The lower the ends are,
	the higher the GROUND LOSSES.   N4KG

	With an apex of only 21 ft, most of the radiation is 
	straight up or at very high angles which makes
	it appear to be omnidirectional.  That basically
	holds true up to 1/4 WL high which is 70 ft on 80M.

	To see much directivity with a dipole or inverted
	vee on 80M, the apex needs to be 100 ft or more.

	I know a few people who have worked DXCC on 80M
	with very low inverted vee's (35 ft or less).  That 
	doesn't make it a good DX antenna.  In this case,
	higher IS better.   N4KG
