Coax Internet Cable: If I have to build one, what am I looking for exactly?

I am considering picking up an audio-grade coax cable to connect the internet wall outlet to the modem. My suspicion is that the digital coax cable that sits between the wall and modem is the same coax cable that feeds into a DAC--but with different connectors. I believe the standard coax connector to feed a DAC is the RCA connector while I need a Type-F connector to feed a coax-based internet service into the modem. 

I haven't seen anything on this forum on this topic. I also don't see any audio brands offering premade coax internet cables (e.g. http://thecableco.com).  

If I have to build my own coax cable to feed into the modem, what am I looking for? AQ has 3 connector offerings, including Type-F, for both 18 AWG and 24 AWG sizes. And their respective 18 AWG and 24 AWG pages list their compatible bulk cable being either "HD6" or "ITA, ITV or MAC 24". 

I figure that I might as well build a coax cable to feed into the DAC while I'm at it. It looks like the HD6, ITA, or ITV are made for different applications. From their price book, AQ says that HD6 is for "Video, RF, Digital, Subwoofer" while ITA is for analog and ITV is for video. From this info, I believe the HD6 bulk cable would be ideal to both feed a modem and a DAC. 

So, here are the main questions:

  1. Anyone know of any premade coax internet cables?
  2. If I need to build my own coax cables to feed the modem and DAC, does the info above look correct?
  3. Can anyone share their experience building coax cables?
  4. Can anyone share their experience upgrading their coax internet cable?

I took a look and the Jade FX-Ag is a very expensive cable.  It is also listed as using a very small 25 awg conductor, which means that the F-Connector is not a true F-Connector but an adapter that I would assume has a 18awg pin.

For much less money, I would look at the DH Labs D-750 which are available with F-Type connectors.   The cable is also a true RG6 design that uses an 18awg solid-core silver-plated copper conductor.

On true F-Type RG6 cables, the conductor itself is the actual pin that is inserted into the COAX socket.  The "F-Type" connector is just the ground shield and a "screw-on" assembly that holds the cable onto the connection.

I have had excellent results using a F-Type ground loop isolation, like this one below:

https://www.amazon.com/Ground-Loop-Isolator-Transformer-Eliminator/dp/B08FRGH4X2/ref=sr_1_17_sspa

It's different than the filter mentioned above.  I think the filter above uses Ferrite magnet filters which the conductor is looped through.

The link I posted is really an isolation transformer for the cable box.  I like it because it screws directly onto your cable modem or receiver.  You don't need two separate cables to place the filter inline.  This has significantly improved both audio and video quality.  However, it may not work in some equipment, especially if the equipment requires two-way communications.  It's cheap enough to try and you can take it out if you get internet connection problems or other weird things.
