Help with J antenna design
Plan is to build a J antenna for 20 meters using 1 inch EMT conduit.
Antenna will be supported at the bottom by a 4x4 post in the ground and at the 30+ foot level with a fiberglass bracket bolted to the eve of the house. The upper most section will be a fiberglass 1/2 wl antenna thta used to be used for CB. I am looking for a program that will allow me to calculate deminsions for a project like this. Feedline will be 50 ohm coax. |
