The receivable USA , Digital Broadcast Tv stations/channels are.
WNPI-DT UHF Digital channel 23 , PBS , 79.6 miles.
WCFE-DT UHF Digital channel 38 , PBS , 107.6 miles.
WWNY-TV VHF high band channel 07 , CBS , 100.6 miles.
WNYF-LD UHF Digital channel 18 , FOX and digital sub channel WWNY-TV , CBS , 79.6 miles.

That makes all the channels UHF , because WWNY VHF channel 07 is also a digital sub channel on WNYF.
_____________________________________________________________________
The distances of the USA Digital Tv stations are far away , and , there also is the 2 Edge Path obstructions = hills and mountains.

The CM4228HD UHF antenna is a panel type antenna.
A panel type , broadside , antenna with a reflector behind the bowtie receiving elements does a excellent job of receiving long distance Tv transmissions because the long distance Tv transmissions tend to move up and down and side to side over long distances.
The , up and down / side by side , stacked reception elements receive the wavering signal.
_________________________________
All of the USA Tv stations are weak signal strength.
WNYF is the weakest. If<->notice that the word is If , not will be not , received reliably.
And you can choose to reach out for WWNY VHF channel 07 with a VHF antenna with a VHF high band channels 7 thru 13 antenna , then use a , Antenna Craft Y10-7-13 antenna aimed at about 190 degree magnetic compass direction the direction of channel 07.
(( There are currently no high gain broadside type/style VHF antennas and have not been for , many , many , many , years. ))
Here is how to aim antennas.

__________
The CM4228HD and Y10-7-13 , antennas are connected together with a , UHF/VHF combiner/diplexer.
Model number , EU385CF-1s.
The CM4228HD antenna connectes to the UHF connection of the combiner.
The Y10-7-13 antenna connects to the VHF connection of the combiner.
The remaining connection of the combiner is connected to the amplifier.
Separate the CM4228HD and Y10-7-13 antennas by about 3 feet on the same mast.
The CM4228HD on top , the Y10-7-13 on the bottom.
__________________________________________________________
The CM3671 is a Big highly directional antenna , the construction quality is medium to low.
The CM3679 is a Big highly directional antenna, the construction quality is medium to low.
The CM5020's V shaped UHF reflectors is very small , the small V shaped UHF reflector does not provide as much gain as larger reflectors.
_________________
My evaluation of the HD Slacker, is , the reception ability is about the the same as Winegard , HD7694P / 95P / 96P / antennas.
The HD Slacker has a phasing loop of wire in between the 2 antennas because the 2 antennas are too close together for phasing without the loop.
And the antenna looks like a up side down antenna.
The UHF antenna should be on top and the VHF antenna should be on the bottom.

Use New coax and connectors and connection hardware outside.
To keep Weather/Water out of outside connections.
Use the coax that has the Compression type connectors , not the old type crimp type connectors.
And to make double sure that Weather/Water stays out of outside connections use coax seal.
