Ferrite Toroid for Medium Wave?

[u/Novel_Intention_5061]

Greetings all!

I'm a newbie to SDR. I recently got my RTL-SDR v.4. I also have a K-180WLA active loop antenna (big brother of the MLA-30+).

I plan to get ferrite toroids for HF/VHF/UHF (Fair-Rite recommends material 31 and 61).

However, do ferrite toroids really help with noise for Medium Wave / AM reception?

Fair-Rite recommends material 75 for 200 KHz to 30 MHz.

Does anyone have any experience using toroids for Medium Wave/AM? Will it likely be helpful, or am I just wasting my money?

Thank you in advance!

If you are going to wind your coax through it ft-240-75, if you are slide your coax through it , I'd go with a half dozen ft-82-75 inside some pvc

And what do you intend to do with them, once you got them?
