im not a very good expert with networking. I have heard that the cross talk (or magnetic interference I think?) will stop it so after 100ft I think the connection would go bad.
You are going to need to put a switch half way down the length. If you don't have power then you can get POE powered switches. If you can't put a device half way, then you will have to use fiber to go 600 ft uninterrupted.

If you only need 100TX connectivity then this would be your POE repeater. Much cheaper if you have power available in the middle and can use a conventional switch.
