The Copper Cactus J-pole Antenna by N7QVC

This is the sizzling little skyhook made by N7QVC.  This is a co-linear antenna covering 2 meters and 70 cms.  I made one of my own which is in operation as the FM base station antenna here at N7UR.  All of the parts (less coax) were purchased for about $8.00 from HOME DEPOT...construction and installation time took about an hour.  CONSTRUCTION TIP: All of us old pipe sweaters keep a rag with flux on it (don't worry how dirty this rag gets...they seem to work better the worse they look) immediately after you sweat (solder) each connection wipe around the joint with your old flux rag....your joints will look much cleaner and professional.
