You should not need additional amplification (it will likely cause NEW problems), you need to identify and resolve the fault that is specific to reception channel 13. Your channel 13 is calculated to be line of sight with a signal margin that should, once antenna gain is added, exceeds 50 dB. In plain linear numbers, that's 100,000 times more signal power than the tuner needs. If you amplify at all, you will boost all of the other signals, some into the range where they will likely overload either the amp or the tuner(s).

Common reasons for a single channel to be of poor reception strength or quality:

Antenna placement - partially blocked signal path, often exhibits as being specific to a single channel whether UHF or VHF.
Localized interference from electrical or electronic devices and wiring.
For VHF channels 4-13, strong FM signals. Requires some math and additional detective work to develop that theory.
Fault in a cable or in-line device that causes it to "suck out" a particular frequency or set thereof. Worn-out female F-connectors or coax center conductors that are a bit too short are a common faults.

You can try a four-port amp like the one we carry and give it a shot. It won't overload internally, but it's not possible to be assured that the same won't happen downstream.
