On both cables I was putting at the tuner end because that's what the instructions said. I just tried putting it at the antenna end because that will be possible in the location where the antenna will be. I pretty much got all those channels back again so that's pretty great. The reliability is still not as good as it was when the amplifier was by the tuner on the included coax, so I'm a little puzzled and I'm also concerned about this coax that I've already placed in people's homes... Probably going to look at a different manufacturer...
