R1155 Loop
Hello all
Have just finished building a D/F Loop for the R1155. Can anyone who has done similar tell me what they used to connect the two together, in my case about one meter. I know it has to be twine screened cable so would RG58 be best or would a lighter audio screen cable do the job. Many thanks Mike. |

Re: R1155 Loop
Hi Mike,
Have a loop myself - you need to use 2 wire twisted pair screened cable, not coax. If you don`t have the correct`c` shaped Jones plug with its internal cap, you will require a small air spaced variable capacitor of 75 pf at the plug end across the loop pair to tune for mamimum sensitivity. John. |
