How many TVs can be hooked up to 1 antenna
do I need extra boosters or anyother parts to connect other TVs
This is tricky but with a non-boosting splitter, make sure it is one for antenna's and not cable, you should be able to hook up a couple of TVs if the signal is good and strong. If you live far away from the stations then you might need a booster. I live in a low area and I was able to hook up 2 TVs without a booster but when we went to 3 I needed a booster. Also found out it was because of the Tuner in one of the TVs that forced me to get a booster. Hope this helps.
