Ray, 

  Not too much to google.. just cut one 136 ft piece of wire and from 4 to 20 pieces of wire 134 ft long.  The 134 ft long pieces are the radials.. put up as many elevated radials as you can manage.. Make the radials about 6 or 7 ft above the ground so you can walk under them and gull wings are OK.  The 136 ft piece is the vertical section. Put as much vertical as you can manage and the rest horizontal. .. Using SWR bridge or better yet an antenna bridge .. trim the horizontal to resonance...  you should be left with something in the order of 24 ohms +j0 



You can tune the antenna inside the shack with an antenna tuner... if it doesnt tun exactly like you want add or subtract some cable length.. (10ft at a time) untill it does.   ORRRR you could put a use a 75 ohm section of cable next to the antenna as a matching section.. then just attach your 50 ohm feedline to that. 



WOrks great.. worked/ confirmed 43 countries since last Sept 1.. 



Let me know how it works

Hello all ..... go figure I made an 80 loop vice 160.  Well no matter now I 
have a 160m dipole up now and it is doing good. but the inverted L now has 
me interested will have to google this hi hi  too much wire too many trees 
and an understanding xyl  now the my daughters are telling me enough. 
Thanks all for responding
