This tri-band j-pole antenna system is a good choice for radio amateurs who can only erect one antenna structure on their property.  AF6SA has designed a fairly compact and lightweight antenna package that can be built with simple tools, some copper pipe, and a few PVC sections.  According to AF6SA, the tri-band j-pole covers the 145/220/440 MHz amateur radio bands.  The antenna combines the coupled resonator approach of K9AY with quarter wave stubs to achieve low angle radiation.  AF6SA provides a link to the NEC-based antenna modeler and optimizer.  This would make an excellent weekend project for  your club's repeater or for home use.
