I say the KT200 is being overloaded by the strong signal strength Tv stations ,
WJHG , WTVY , WMBB , WPXG , WDHN , WECP.
Antenna system #1.
(-->If<-- Notice the word -->If ) it is WABW-DT REAL VHF Low band channel 06 , virtual number (14.1) PBS , that you are after with your All band antenna.
I recommend use the All channel antenna you have as VHF Low Band channels 2 thru 6 antenna with the KitzTech KT 200 amplifier.
Use a HLSJ = High band/Low band Separator/Joiner , as a filter connected between the antenna and the VHF low band input of the HLSJ.
Connect your antenna to the VHF low input and the output of HLSJ to the KT200.
Or can use A Winegard HD7084P antenna in the place of your antenna , with the HLSJ.
The VHF high connection of the HLSJ will have a 75 ohm terminator cap screwed on.
The HLSJ used this way will only pass the VHF low band channels of 2 thru 6.
And act as rejection filter for the other Tv channels , VHF high band 7 thru 13 and UHF channels 14 thru 51.
Type in the letters hlsj in the solidsignal search box ,

Aim your all channel antenna at WABW-DT channel 6 at 72 gegree magnetic compass direction.
Here is how to aim antennas ,

The antenna will be a Fixed Aim Antenna aimed at about 72 degree magnetic compass direction.

Antenna system #2.
To receive the other Tv stations of different directions ,
Use a Winegard HD7698P antenna with a Antennas Direct CPA-19 preamp.
The CPA-19 preamp is resistant to overload.

The 2 antenna systems are Separate antenna systems and are Not connected on to 1 coax.
The 2 antenna systems are Separate antenna systems All the way to the location/s of the Tv/s.
And are connected to a ,
http://www.mcmelectronics.com , #32-4425 , remote control A/B antenna switch at each Tv location.
____________________________
For 1 Tv connected use No splitter.
For 2 Tv's connected use a , HFS-2D , 2 way splitter.
For 3 Tv's cannected use a , HFS-3d , 3 way splitter.
Buy the HFS splitters at ,
http://www.solidsignal.com or

A/B antenna switching is Channel Surfing Friendly , press the button on the hand held remote control and keep on channel surfing.
________________________________________________
Using 2 Separate antenna systems means every thing , the Tv antennas the preamps are separate splitters and coaxes. Are Separate all the way to the Tv locations.
As alway , trees and tree leaves do a good job of , reflecting , reducing , blocking Digital Tv reception and so do buildings and other obstructions including your own roof and house.
It is best to locate the antennas at a location that has the least obstructions to no obstructions in the directions of reception including your own roof and house.
The Tv's Must Channel Scan for the Broadcast Tv Channels , often named the 'Air Channels' or 'Antenna Channels' in the Tv setup menu because the Tv transmissions travel through the air from the transmitting antenna to the receiving antenna.
Some Digital Tv's will automatic channel scan for cable Tv channels.
Go into the Tv setup menu and select , 'Air Channels'/'Antenna Channels'.
Do not channel scan for cable tv channels.
____________________________________
Digital Tv tuners can develop - Digital Glitches - that are not cleared out with a simple channel scan.
Do a Double Channel scan.
