am considering putting up a hamstick dipole for 80 meters, mostly for cw and psk work so power isnt an issue. if i run this thing as a vertical dipole off of the back of the house is the mast material of any great importance? ive got some metal push up poles but thinking i may need to go with some pvc pipe as the shield leg of the dipole will be next to it. if pvc could i slide the sheild leg down into the pipe for added support? ideas? opinions?
