I have for a number of years used a full wave loop. I ran the wire
inside a piece of black plastic water pipe which is about 2 inch
diameter. Close the loop with a T-connector made for this pipe and
bring the ends of the wire out the open T. Connect one end to center
connector of Coax and the other end to the braid of the coax. I use
RG-58 or 59 since it is receive only. Hang it horizonal supported by a
cross made of wood strips and setting on a tripod. I have even just
tossed it up on the roof and let it lay there. It has a cone shape
node pointing to the sky. The pattern is about from 15 degrees after
AOS to 15 degrees before LOS. granted it would work better if you
raised it higher but has worked just great for me as discribed. I can
send a picture of it if you wish. Good luck and 73's << John
