Do you add shielding to the FRAs?
Do you mount the FRAs and preamp to a board, so reduce the risk the host will damage the fine wires from the FRAs?
Hello,
I started with loops but the ferrite are definitely easier to package and 'tune'. With a 15m cable, I only instruct the host to place it anywhere away from any obvious source of noise and watch with the "FFT html page" provided by Mike. Sometime on the ground below the bed, sometime on top of a wardrobe, etc... Not optimal for sure but again, my host are not engineer and I try not to bother them more than a few days
I have not shielded the ferrite rod, only using shielded cable between the detector and pre-amp. My antenna packaging was discussed at: Thread 3983. Since then I have read post that indicate 'L' is better than 'X', but too late (and it works).
Thanks and regards,
Marc
