A:Answer (If any of my 4K QLED televisions should fail, I have this as a
backup to use until I can get a replacement in place. So, I
haven't really used the LG yet.)
But, I have tested the LG, and it performed well. Just how
well it would perform with OTA signals depends on the
quality of your OTA antenna and the signal quality of the
particular channel that you are watching.
No, it is not designed especially for streaming.
I don't think that this TV is 5G capable, but if you have 5G
it should be backward compatible to 4G or 3G devices.
