I could use a little advice on construction of an end fed dipole. I'd like to make a 1/2 wave 80M end fed horizontal wire antenna, fed by 50 ohm coax. I'm guessing that the center conductor becomes the radiating wire of the antenna. Since there's no counterpoise or 2nd leg, I guess the coax shield just goes unused? Trim it back to the insulation?
It looks really simple so I must be missing some details.
Future question, if I trim it accurately enough to become resonant on 80, can I add a 40M trap later and use it as a dual band? More traps for more bands? I've never thought about traps before, so I'm ignorant to their use. I'd like to build my own if possible but I don't even know what they are made of.
