56.1 is a low power station, and I don't know what is on it.
8 is a strong station, but it is on VHF 8, you need the right antenna and/or amp.
It is up to you how much you want to play with it.
I have a big vhf antenna - I was going to try to get Wheeling with it but haven't played with it yet.
I have a 2 bay antenna that actually works well, but not using now.
I have a CM7775 pre-amp - UHF only but basically new condition.
I have a CM7777 pre-amp - same condition, am currently using but I think it is too powerful for my current setup.
You might want to try different setups, without moving your current antenna since you have a few stations.
You need a better antenna
If you are picking those stations up with the gemini and rca antenna, that is a good sign. Neither of those are really that good.
You can PM me if you need to.
