Antenna amp or Distribution amp??

Hi all,
I am new to this but am having fun so far.
My situation north of Toronto:
I have installed a Digiwave ANT-2280, combo VHF/UHF antenna on a 10' mast with a 5' tripod on top of our house (about 40' overall).
The coax comes to a second floor bedroom where we get good reception, down to about NM 6.3dB on the list.
Then we go through two splitters and feed two other TVs on the main floor. That is where the signal becomes weaker and we are only seeing channels down to about NM 30dB.
We have way too much (existing) coax, about 200' or more in total.
I think an antenna amp or distribution amp could help. (BTW, what's the difference?) Can anyone suggest something?
Thank you all in advance.
This is a great resource!!

200' of RG-6 should have no more than 12 dB loss. Be sure you are accounting for the cable correctly, you only count the cable that the signal has to travel through to get to the tuner. Don't add the length of cable connected to other splitter ports, going to other TV's. If you're using a typical 2-way splitter, expect 4 dB loss through the splitter. When you add the second splitter, you have another 4 dB of loss...

So as I add up the losses, I'm not 100% convinced that we have accounted for the 24 dB change in system performance. Look for the possibility of loose or bad coax connector(s). Use one splitter, with the number of needed ports. Unused splitter ports add loss with no benefit to you.

A Channel Master CM-3410 distribution amplifier can be added ahead of the splitter if needed.

To go down the Digital channel list and reach out for ,

Install a Winegard HD7084P antenna with a Winegard HDP-269 preamp aimed at about 170 degree magnetic compass direction.

Here is how to aim antennas ,

For 1 Tv connected use No splitter.

For 2 Tv's connected use a , HFS-2D , 2 way splitter.

For 3 Tv's connected use a , HFS-3D , 3 way splitter.

Buy the HFS splitters at , , , ,

The correct way to connect Tv's is to use the splitter that has the correct number of outputs to the Tv's.

For 2 Tv's connected use a 2 way splitter.

For 3 Tv's connected use a 3 way splitter.

And so forth.

As always , trees and tree leaves do a good job of , reflecting , reducing , blocking , Digital Broadcast Tv reception , and so do buildings and other obstructions including your own roof and house.

It is best to install the HD7084P antenna at a location that has the least amount to no amount of obstructions of any type or kind in the directions of reception including your own roof and house.
