For a 20M J-Pole look at N1LO's web page -
http://www.qsl.net/n1lo/antenna.htm

I have used his 10M collinear super J-Pole for years in my HOA-neighborhood
back yard hanging from tall tree limbs.  For the last 2 years it has been
supported by a 55 ft fiberglass mast.  It is my year-round go-to antenna
for checking conditions on 10M.
