The CM-3414 and the CM-3410 which it's based on are very good distribution amplifiers. As with any amplifier, they can't compensate for the negative effect on SNR caused by cable, diplexer and splitter losses on the input side of the amplifier.

In other words, the CPA-19 preamp installed at the antenna would be the best option. An amplifier installed down stream of the second diplexer will not overcome the SNR hit of the cable or diplexer losses from the antenna to the input of the amplifier.
