Is it safe to do this? antenna ground tied to RCA input ground?
I have a CMS R45OAV stereo/radio amplifier
and in video/RCA mode i hear static and the radio slightly leaking into my speakers and it was getting on my nerves so I tried seeing if I could maybe fix it and started trying things
and it works EXTREMELY GOOD just using a wire between the antenna ground output into either of the RCA input grounds.
and now no more staticy radio leaking into my speakers. sound quality is great too.
i want to know if it will hurt the amplifier or radio circuitry or something by doing this over the long term when im not using the radio?

I can't think of any reason why it would do any harm. With a direct lightning strike into your antenna your radio will probably break down with or without that wire, without lightning I can't think of any issue it might cause.

ok thanks I just thought its a weird thing to do and its weird that it fixes the problem with noisy radio static and voices leaking through my speakers.
