1. You cannot use an OTA only tuner for Sat but you might be able to use it for cable, depending on the cable service and the tuner. I am not an expert there, as I have never and will never have cable (at current expansion rates, they will reach my house in about 100-200 years).
2. I don't know what an STV is, but most tuners will have multiple outputs but will drive one at a time. You might find one that can drive more than one output at a time, but don't expect it to be a standard feature.
3. STV? Is that NTSC? OTA tuners will have NTSC tuners in them, or at least that is my experience. The cost of the NTSC tuner is very small, so they don't generally leave it out.
4. The remote will have a range like a TV remote. If you want to use it in different rooms, you want an RF remote. You could do it with an IR remote if you have a remote repeater system, but you probably don't or you wouldn't be asking about the remote range.
5. Brands? Most brands are OEM units from somebody else and often one unit will be sold under as many as 3 different brands.
6. All antennas have just one output, which can then be split. If you try to split too many times, you might need an antenna amp, but that is probably not the case unless you are driving long runs of cables.
