Amphenol is one of the top coax suppliers, stick with them if you can.
The Amphenol Global Search page, below, that has several entries that my old computer can not talk to is VERY slow to respond. Hopefully you can get more information from them.

INSERT: Just found TFC-10;
created by(?): Times Fiber Communications http://www.timesfiber.com
also made by Amphenol: https://www.amphenol.com/gsearch/ctfc-t10?page=1

The cable you have is 75 Ohm and has a shield layer that is extruded Aluminum, not foil like the indoor ones most folks are used to. As such it is probably a little more sensitive to repeated bending. If outdoors (as it is designed for) it probably should be restrained from flapping in the wind, repeated bending may eventually crack the shield, causing signal loss. (the flapping and bending is speculation on my part, based on the descriptions on the manufacturers website)

I wonder why TFC-T10 used extruded aluminum shielding which can break easily. What were they thinking? And why would cable companies prefer it over RG6?? The reason for my pixelization could be partly broken aluminum shielding.

Also it's frustrating the websites don't have have very basic info like how the copper of it compared in size to the center copper of the RG6. The following is the TFC-T10 at left side compared to the RG59 cooper. The RG59 copper is smaller. And it is too loose to fit in the Isolator and even cable box. So I need to buy RG6 online to make it fit and work.

One site says you can directly connect RG6 to the TFC-T10 with an 'F' male-male connector. Since they are both 75 Ohm you should be good to go.

Is it not a typo? Shouldn't it be 'F' female to female? Because both the TFC-T10 and RG6 are male.

The amplifier you are looking for would be an "Antenna Booster" or a "Distribution Amplifier." Both require power and actually amplify the signal. If you see some that advertise improvement but do NOT require power, they are probably lying.

The Antenna Booster would be the lower cost option and would likely help/hide the problem.

Distribution Amplifiers come in a wide range of capabilities and costs, from \$$ to \$$\$$\$.

Cheers,

That information is often in the technical datasheet from the manufacturer, but is still often hard to find.

If the connections are going to indoors and left alone, not moved around, you can put a couple small "S" bends in the enter wire so it will make contact.

Well, Google agrees with you.
However that is one of the crazy wordings in electronics. If you are talking about the plug on the end of your electric toaster, that is Male because the only mating parts are the pins that go into the wall outlet.

If you are talking about a connector that has a shell and one or more conductors, then the sex of the shell is often used. More common, at least in military connectors, is to call them Plug and Receptacle.

Some of this type connector can have contacts that are either Male or Female, in that case the contacts are called Pin and Socket.

Here are two photos of a Receptacle, one with Pins, the other with Sockets.

Not sure all the above helps your problem much.
