I have an antenna that is just a loop of wire operating at HF (8MHz) and nearby computer induces noise on it. How to filter this noise on the antenna itself. I have no access to equipment past antenna terminals.
Wire loop is ~2.5 m 16 gauge wire, measures 3 – 4 uH inductance and no resistance to speak of. When connected to terminals it is resonant and resistive part of impedance varies in the range 200 – 1000 Ohm.
I tried clipping (unknown) ferrite beads on the wire but far did not have much luck with it. In fact it seems it makes it worse.
