Flower Pot Antenna
A few years ago a made one of VK2ZOI's dual band flowerpot antennas. I was surprised how well it worked and a few others tried it and found it worked very well. Here is a link to his webpage with instructions for making several of his designs. They are end fed coaxial dipoles with an interesting design to make them dual band and colinear for increased gain.
I've found a few examples based on his design I intend to build so put them here to remind me and hopefully help others.
