Question: Can it work with a cable splitter. I have it in the garage when I had cable TV. Plan to mount it on the roof and route it to the splitter to 2 HD TV's
Document: I put this up on my roof and it worked OK. I went back and moved it up about 4 feet to the top of the roof and it worked much better. I am about 60 to 70 miles South east of Chicago and I pick up all their stations plus South Bend. I am very happy with it. I screwed it right into the roof with mount that was provided. I used 2 , 5o foot cables and connected it to my exsisting cable input. It works on 2 tvs.
I can't tell you how happy we are with this little antenna. We live in the San Francisco area and have become tired of the endless rate increases by our area cable provider. I am not able to mount this on the roof but I placed it outside an east window upside down (opposite from the picture) I picked up all the local networks except local channel 5 but amazingly we  receive a CBS channel from Sacramento. I am able to watch the NFL in HD without paying a dime to the cable company.
With cable (no converter box) using the tuner in my plasma TV the audio would drop out momentarily about once a minute. It doesn't do that with the GE antenna. I like that it's powered through the coax, so the power supply is at the TV end. Warning: It won't work properly if you have a splitter or signal booster between the power supply and the antenna.
This really works, unlike the piece of crap I bought previously at a "big box" store (the fact that they all looked like they had been returned was a good hint). I'm getting about 25 DTV channels with the antenna in my attic. It's also feeding my FM tuner through a splitter. No more fuzzy interference when people walk around in the room! It works slightly better on the roof, haven't tried a pole mount yet but I probably will. The built in amplifier makes a huge difference.
Okay, I live about 50 miles or more from most TV stations in my area. When I tried it for the first time the antenna didnt work at all inside the house at ground level, then I took it upstairs and stuck it out the window and got about eight of the closest stations, so then I installed it on top of the roof and connected it with a 50 ft. coaxial cable that I ordered with the antenna.
Made routing the coax pretty simple. I run the power adapter ahead of a splitter and use two TV's with no apparent signal loss. This little bugger is just fantastic. I'll upload some pictures if I can figure out how.
We hooked this baby up and it was quick and easy. We maxed out the 100 ft of coax AND we are running 4 TV's off this antenna. The picture is clear and crisp, much better than the non-HD basic cable we had before. The unexpected bonus is that we get 29 stations...7 more than our basic cable. It should be noted that we live in a suburb of a good sized city, but this gave us reception of stations with towers 55 mi. away.
The first one of these we bought we used in the Twin Cities, so a fairly dense area. We mounted that one on an old dish on the roof of our 2-story house and hooked it up through the existing cable from the dish. I used one of those websites that tell you where the signals are coming from to position it. It worked great, we got all the over-the-air channels clear as a bell.
I ordered this item hoping that I could pick up the three network channels from my apartment balcony. It is not installed permanently yet. I just put it on a chair to see if it would work. Much to my surprise the HD network channels jumped out at me better than what I get off DIRECTV. I am also receiving other area channels that I didn't even know about. The TV towers are 25 to 30 miles from my home.
Roof antennas are not allowed in my development. We have Directv which everyone knows stops working in really bad weather. We wired our house to have a separate antenna feed to the roof and put this up. It's about the size of a paperback novel and works amazing. It's amplified, you put this little part on the wire near your TV and plug it in. We live nearly 30 miles from Austin Tx and get perfect HD reception with this.
Answer: I mounted it on my roof but did not get good reception.  It was very sporadic depending on the weather.  It should work with a splitter, however, if both TV's are on at the same time, I would guess that you would get some signal degradation.
