HAM RADIO: Direction Finding Loop Antenna : Frame Antenna : Wire Winding :

Hello, Thanks for watching, a little time back Callum DX Commander and I ‪@mike-M0MSN‬ were discussing a way in which, it may be possible, to find an individual that was causing intentional QRM. Having given this some thought I have come up the the idea of a DF loop similar to that used by wire framed antennas. I have based this loop on a video I watched from Paul OM0ET (   / omoet  ) This is a great build video:    • 5-band FRAME ANTENNA - how to made   However Paul's antenna is for general use on multiple bands I have adapted it for use on 80M only. What you will need: Plastic pipe: Two lengths 1: 25mm Dia x 74cm, 2: 25mm Dia x 100cm. Loop length: 16.92 Metres of DX10 (you will need 25 metres to be sure). Counterpose: 5 metres(or the remainder of the wire). Short length of coax and a SO239. Small terminal connector. Find the centre of the short length of pipe and drill a 3mm hole, offer this pipe up to the other 100cm pipe, so that one end of the short pipe is at the end of the long pipe (side by side) then mark the hole across to the longer pipe, and drill a 3mm hole, you should now have a 3mm hole 37 cm from the end of each pipe. This is the centre of your cross. On the 100cm pipe draw a line at 37cm from the hole (on the longer side) as this will form the end of the wire frame, you should have 26cm of pipe left under this mark to mount the connectors and stand. Next mark 9 holes 1cm a part starting at the ends towards the middle of each pipe (use the 37cm mark on the longer pipe) drill and then start to wind the wire. Start winding the wire from the hole closest to the middle on the longest side of the longest pipe. As clear as mud ( just watch the video) I will continue to look into DF Loops and if I find a better one I will update and make it, If you have any designs or have any DF antenna knowledge please feel free to drop me a line. Cheers and good luck. Please note: Your mileage may vary and this antenna does not guarantee success.
