Can anyone recommend a multiple output amplifier for local antenna use? Other than the 2 TVs with DTV, we currently have 3 others that get watched on locals a lot. Would like to be able to add TVs to our new guest rooms when they are complete.
Any amplifier with the range of frequencies up to the top of UHF band (900 mhz) will work. Most amps are designed to be one line in, one line out and you would use splitters to hook up all the drops. Its the number of splitters and coax lengths that will determine how much gain you need the amp to deliver.
There are some amps that are 1 in with 8 outputs these usually only have enough gain to compensate for the splitting but should be ideal in your case. Now if you needed to hook up more than 8 lines then you get a single amp and then hookup the splitters accordingly.
One problem you may have is if you have an antenna picking up 10 different stations some are going to be much stronger than others since an antenna is usually directional. So some signals will be stronger than others and may not need to be amped at all. In the analog days and digital today too much signal can be worse than too little. So amping a signal thats way too strong or way too weak is bad.
My suggestion is to try with splitters without the amp and see what you get. If a channel is poor, try bypassing the splitter and feed directly to the TV and see if ok. If yes than a small amp will be needed. If no good than an amp wont likely help.
Solid signal has a handful of different amps to choose from. If all you have are 3 tvs to hookup an amp should not be necessary. Get a 3way or 4way splitter and be done with it.
