         The 80M1LL is a real performer, both mechanically and electrically, when used as a dipole. It can
also be used as a building block for future expansion to a 2 or 3 element beam antenna. The dipole can also
be separated in half and used as phased !/4 wave verticals. Element halves start with 3" diameter tubing and
taper through 2", 1-3/4", 1-1/2", 1-1/4", 1", 3/4" sections to the 1/2" tips. The 3" and 2" sections are separated
by a rugged fiberglass insulator to allow for the linear loading (#10 copperweld). A solid 2" O.D. Fiberglass
rod, sleeved to the 3" elements, serves as the center insulator.
         The linear loading terminates above the boom and out of the element plane to reduce inductive
cancellation and provide element support. Tip droop is less than 24" and looks better than some 40 meter
elements. The 3 KW, 1:1 balun and phone / CW power switching relay are housed in a heavy wall ABS
cannister at the center of the element. Relay switching requires 12 VDC supply.
