| Mar 24, 2019 at 16:10 | comment | added | rodv92 | well I am building a prototype that I will use as a low power max 10W FM broadcast antenna and/or RX antenna. currently the driven element is 3.22 m long single strand insulated copper wire encased in a 16mm pvc electrical conduit. I am trying to make the resonant frequency a bit below the center of the broadcast FM band so it is 95 Mhz. I used qsl.net/yt1vp/CUBICAL%20QUAD%20ANTENNA%20CALCULATOR.htm | |

| Mar 24, 2019 at 13:55 | comment | added | rodv92 | Basically to alter the resonant frequency. and since i have an antenna analyzer, I would be able to see what's going on when i tune the reflector. So basically : experimentation | |
