Hi OM, It is a dual element feed. You have what appear to be two quarterwave slots, one wavelength apart (probably for better position could you please explain the dual element part? I thought they were used for attachment,look closer and you should see remnants of melted black plastic I sliced off over them. tolerancing). What you offer above actually explains nothing. Change out 9913 to what end? Even RG-58 over that length would serve. in this case its too big for the connectors being used. Attach a USB WiFi for what? To transceive? Why don't you just try it and see what happens? Nothing gonna break and if it works that's the end of it. If it doesn't work, you have more problems than a 4% frequency shift. 73's Richard Clark, KB7QHC |
