Looking for Answers about RCA RCA Outdoor 60 Mile Antenna With Mast - UHF, VHF and HDTV?

yes. You would need a splitter. Walmart sells a 4 or 5 way splitter for about $6 and also sells a 2 way splitter. I've read that you may need an amplifier if you split it to several TVs, or if your cable run is long. I used a 50 foot coax and did not split it. My signal strength was so good I think I could easily spit it to two TVs without a need for an amp. You can buy an amp for about $20 at Walmart, but it runs on 110 power. That is another good reason to put it in the attic as it is usually easier to run power in the attic than it is outside on the roof. If you have a light bulb in the attic, Lowe's sells a screw in adaptor that gives you a plug in at the light bulb fixture.

Yes, where your cable comes into the house you probably have a splitter, you should be able to attach the antenna there. We run four TVs with a one to three way splitter where the antenna comes into the house and use an additional one to two splitter within the house between two adjoining rooms.

Since the antenna is described as UHF/VHF, it is capable of receiving stations broadcasting in either frequency. Channels 2-6 are said to be in 'low VHF' while channels from 8-13 are in 'high VHF'. Channels 14-69 are all in the UHF spectrum. Some channels that have previously broadcast in the VHF spectrum prior to the digital rollout have actually changed to the UHF frequencies and taken advantage of a higher power output.
In the Houston, TX area, for example, there are only 3 stations that continue to broadcast in VHF: 8, 11, & 13. These stations are also the most troublesome to receive for viewers more than 30 miles away because they all transmit at a low power output of 17-22kW compared to 233kW-1000kW for UHF stations. Channel 2, however, actually broadcasts at 35 and has 1,000kW of power output.

SMALL END .

TV signals do not pass thru metal well. Unless you have alunimum siding on wour house, it should work about as well as it would outside.

Yes. The cables and connectors are the same.

No. The transformer is a passive component, requiring no power.

Yes you can have conected as many tv's as you wanna, you just need obviously coaxial cable and a splitter, even you can use the wires you have for your dish or cable

Nothing to plug in. Only aluminum and a short plug that you connect your cable from the TV to.

It does not come with what is needed to ground it.
