Maximum length of coax cable

[Chris Holley]

Good evening all

Does anyone know if I can connect to a TV aerial 80m away? I’ve got no way of installing a new one any closer.

can it be done with some kind of booster powered from the TV end? If this is achievable, can anyone let me know what type of coaxial cable and booster is required.

Thanks

Hi
Thanks for the quick reply.

The signal to the other TV in the same building looks good but it’s a lot closer. I’d there anything I can do to check signal strength?

If it needs to be amplified from the aerial end, will this need power?

thanks
