Im thinking of building my own antenna. I can't find this answer, could I split the signal for 2 or 3 TV's. Also, what's more ideal, 8, 9.5, or 10 inch whiskers. I'm about 8-10 miles from the transmitters.

I have the logitech z-680 5.1 speakers and they are from the US so it uses the 110V. But I want to use it overseas for 220V. What kind of step-down transformer will I need? I'm not sure if 2K VA step down transformer is enough power or more than enough. How about 1K VA? What if I don't use the speakers full blast and keep it down to low volume, will that ensure the wattage won't go over say a 200 or 300 watt transformer? I'm assuming that 500 watts means if I were to blast it 100% then it would use 500 watts. But for everyday normal levels, should it be okay using a 200 watt step down transformer?
