How to connect both cable and antenna to a single coaxial RF input?
So i bought a new Plazma model Vizio p42hdtv - this TV had 2 sepparate antena in's. One for HD digital and one for reg cable/TV.
I was planning on running cable staright out of the wall for reg cable(no cable box), and connecting to an outdoor antena for the HD signal, to get both.
Then my p42hdtv broke and was replaced with a Vizio VP42hdtv. This is the newer model from what i gathered, but it comes with only a single RF antena in. Is there a way i can splice both signals in to this one input? maybe a 2 signal to 1 converter or something?
can anyone help me out...

You're better off just using an old VCR to tune the cable RF input, and connect the VCR's composite video/audio output to one of the TV's composite video/audio inputs.

Unless i'm mistaken, you need to connect the antenna to a set top box to decode the hd signal. Then you use component/dvi/hdmi for the signal. This will leave the rf open for your regular tv channels.

You can use this. It's totally low tech but it will accomplish what you want.

actually from another boared someone said that you can not splice the 2 signals together.
But.. i connected regular cable to the TV, then scanned for analog chanels. After that i scanned for digital chanels and to my surprize i actually picked all the local OTA HD channels and not only that but they all come in perfectly.
Is it now standard for regular cable to carry HD signal as well without anything extra added to the line?

Yes. It is essentially the same signal as floating through the air to an antenna. But probably in a slightly different RF format. Most cable companies have been putting this out on their lines for free. (well, it's either free or it isn't there, they can't charge for it) It is a different frequency than analog or digital cable, or any phone/internet they may offer, so it doesn't interfere with their pay products.
