Disconnect and remove the CS2V.
I am saying 1 antenna connected at a time.
The CM4228HD or the DB8e.
The CM4228HD is a bigger antenna and as such , receives more signal.
The DB8e is a bigger antenna and as such , receives more signal.
You can use the CM4228HD or DB8e to try for better reception of the USA Tv stations.
Remember to rescan for channels.
Like the CS2V , The CM4228HD and DB8e will also receive the Canada Tv stations.
I did not recommend the CM4228HD and DB8e to start with because the antennas are big antennas.
((Many people have the mind set that Tv antennas are Evil , so a Small Antenna is a Lesser Evil , and some how the lesser evil can be hidden.))
I can not say for certain that the - Other - USA Tv stations will be received reliably.
Remember to rescan for channels.
You will notice that I keep using the word Experimental.
Receiving the USA Tv stations due to the Distance is Experimental.
And receiving the Canada and USA Tv stations all at one time is Experimental.
I keep referring to antenna location and aim direction as Experimental , to find the best reception.
Remember to rescan for channels.
CBLT-DT UHF channel 20 CBC might be received with Experimental antenna aiming. The CBC is at 85 degree magnetic compass direction.
Aiming a antenna at the general direction , around the edge of the building , might get CBLT.
Signal reflections off of other close tall buildings might get you the CBC CBLT.
Remember to rescan for channels.
If the CBC is received and some other Canada and USA Tv stations are lost due the the direction of the Experimental antenna location and antenna aiming , then one antenna can be used for reception of the CBC and an other antenna can be used for reception of the USA and Canada Tv stations.
The coaxes of the 2 separate antennas will not be connected on to 1 coax.
The 2 Separate coaxes from the antennas will go to the location of the Tv and are connected to a Remote control A/B antenna switch ,

Saveandreplay has the same Remote control A/B antenna switch.
Remember to rescan for channels.

If you are not interested in Experimenting , that is Ok.
Aim the antenna and receive what is received.
