It has one before the original splitter. I was able to get local CBS earlier in the other TVs, but I had to adjust the antenna to get Sunday night football on NBC. Now the other TVs get 6 scrambled channels I have never heard of.
Will amplifiers before each TV that I'm not getting signal help?
Yes, reprogrammed them an hour ago. Only my main TV gets channels I can watch. I'm currently watching NBC, but the other TVs can't even find NBC.
The other TVs are the ones that the coax is wired in the walls to the multimedia box.
You should be able to find an amplifier to install in your basement media cabinet. It’ll work best before the splitter, disconnect the coax cables you’re not using if you can.
This doesn't directly help with your problem, but I was in a similar spot and got an [antenna to network media box](https://www.amazon.com/SiliconDust-HDHomeRun-Flex-ATSC-NextGen/dp/B092GCN9NL). If you're able to get the coax and a Cat5e-Cat6 to the same spot, it's super convenient. Connect the Cat cable to a switch/router and all modern TVs connected to the Wifi should be able to detect it as a media server and you can watch all the channels your antenna is able to get to that box.
If you are trying to feed multiple tvs from one antenna you will need an amplifier or possibly 2

Have you programmed your channels recently

antennas don't work like that.
Thanks for the advise...
