Can Satellite, Cable and an Antenna signal be carried in one coax cable? I now have cable/satellite so I can have both cable and sat. but is there another splitter that will allow for three signals in the same cable?

Generally - No.
You can use a diplexer to run Sat and Cable; or you can run Sat and Ant.
You can always try to combine an antenna signal and a cable signal, but they are more than likely going to interfere with each other, unless you were to modulate the desired channels to a different frequency/channel. Also, there may be some FCC rules you'll have to follow to make sure you are not broadcasting the cable signal over the air (besides possibly broadcasting the satellite signal) to your neighbors.
However, if you have 2 runs for a dual tuner receiver, you could run Sat/Cable on one, and Sat/Ant on the other.

Actually you could....
When using the diplexer, use a splitter as a combiner into the diplexer.
This will depend on individual cases... More or less if your picking up 4 different OTA signals, and those channels are not in use on the cable side then you can.
As long as the frequency is not in use or it'll heterodyne (I know I spelt it wrong).

Hell, I was more concerned with his neighbors watching something not appropriate.Always make sure you terminate any unused cable outlets/splitter ports or it'll contribute to RF leakage thus causing potential disruption of the Aircraft Band.

Yeah, but they'd probably be REALLY pi$$ed-off if he brought an aircraft down on their roof...!SmityWhity said:Hell, I was more concerned with his neighbors watching something not appropriate.

To do as rcdallas suggested, look at this link http://www.satelliteguys.us/attachment.php?attachmentid=11789&d=1158064663 which is a picture posted by "bertbarndoor" on (Page 3) of another thread - http://www.satelliteguys.us/showthread.php?t=76031. This picture is kind of what you want to do, except he is using it for a different result.gb387 said:
In the upper left hand corner of the diagram, you would subsitute the "UHF Remote Antenna" with a "VHF/UHF TV/DTV Antenna" and replace the "SDTV" with a "Cable TV Connection". The satellite splitter is a normal TV/Cable splitter that operates between 50 - 1000 MHz.
In the bottom center of the picture, this satellite splitter is also a normal TV/Cable splitter that operates between 50 - 1000 MHz. However, the two outputs would go to where ever you needed the two outputs, or skip this splitter and go directly from the Diplexer VHF/UHF connector to the Ant/Cable connector on a receiver.
The only problem with this setup is: If you are not using a cable box, or a TV that can receive "digital cable" then you probably are using an analog cable system in which the frequencies for Cable Channels 2 - 13 are the same as TV Channels 2 - 13. Just like when you are in the country, you can not receive Channel 5 from 2 different cities when you are half-way between the two cities. You may be able to compensate for this by using modulators, cable boxes, or other techniques, but this may be more trouble or costs than its worth.
In case you do not know, diplexers are different than splitters (which usually can be used as a combiner). I think you can find 2 diplexers for <$10.
This is one site with many documents: http://www.solidsignal.tv/dishpro_installation.asp
Including this one: http://www.solidsignal.tv/dishnetwork/Installation_Documents/The_Ins_and_Outs_of_Diplexers.pdf which is everything you wanted to know about diplexers.

I'm not the welcoming parade, but welcome.t.scott said:
An A/B switch could be an option to switch between two signals of the same frequency band such as an Antenna and Cable, it would require an additional cable; and gb387 is looking to avoid another length of cable.
