With permisssion of W3EKT, I am forwarding this to the 160m reflector. The
lazy U maybe useful to others, espically those with a smaller lot.

>For the CQWW 160 SSB contest I added 65 feet of wire to each end of my 75
meter >dipole so I could make SOME contacts. Dipole is 35 feet at center,
ends 10 feet >off the ground. I did OK, on Friday night, barefoot TS-850,
no DX...called them, could not work anyone.
>The next day, I went thru my antenna folder and "re-discovered" the "Lazy U"
>article from the winter 1992 issue of Communications Quarterly. Went out
in the
>yard and "reconfigured" my 80 CW inverted Vee, which is also 35 feet at

wire

>Saturday night I worked P43, V47, XE, & KP4 who could not hear me on the
low dipole, >but I got thru on the Lazy U. Conditions were different then,
so more testing will be >done. Again, barefoot TS-850, 100 watts nominal. I
also managed OK, NM, & CO on the >U.

>The part that caught my eye was "NO radials are required." Therefore, it
was a quick >& dirty way to radiate SOME vertical signal on 160! Nothing
magic, just a vertical >dipole with whatever you can get vertical & the
leftover "ends" run out horizontally. >
>If you have an 80 foot tree, results should be much better. Run 75 feet
vertical, >pull 90 feet off top & bottom. Feed in center or on the bottom
end with a suitable >PI net, but that takes more effort! (I'm lazy)
