Consider the associated frequencies:

OTA: 40-806 MHz
Cable: 5-1002 MHz
MoCA: 1125-1675 MHz​

MoCA can coexist with either OTA or Cable TV/Internet, but OTA and Cable cannot share coax. That said, many have employed an antenna/satellite diplexer as a workaround to supplant the cable signal with OTA on a single coax run. See >this post< for more information and an example.

edit: p.s. Also this:

Re: antenna/satellite diplexers

Though we're not working with satellite signals, antenna/satellite diplexers can be helpful in some MoCA setup scenarios. The difference maker is that the MoCA technology employed in TiVos uses frequencies up in the satellite range (MoCA "D band") ...

Signal frequencies:

OTA: 54-806 MHz
cable (TV/Internet): 5-1002 MHz
MoCA (D band): 1125-1675 MHz
​

Diplexer passpand frequencies:

ANT (VHF/UHF) port: 40-806 MHz
SAT port: 950-2150 MHz​

... allowing use of a diplexer for merging or splitting OTA & MoCA signals.

Some users have used diplexers to isolate OTA and CATV coax segments while allowing MoCA to flow between the segments through the diplexer "SAT" port (not needed by you, owing to the planned physical separation); to conserve OTA signal strength while delivering the antenna signal to a single outlet of a MoCA-enabled multi-outlet coax plant; or simply to split MoCA & OTA signals onto separate coax lines, at a slightly lower signal loss than would be experienced using a 2-way splitter, when each line only needs the associated signal.

Sounds like I might have to take the MoCa off the coax back to ethernet and use the ethernet jack on the Bolt and the coax for only the Antenna.

This would most certainly work, but would require an additional MoCA adapter at the BOLT location to supply the BOLT with its wired network connection, as you alluded to in your OP.

... or will I need to stop using MoCa for the internet which means I'd need a MoCa to Ethernet at the location of the BOLT to use the ethernet port

As a follow up the diplexer would it allow the the Cable/MoCao and the antenna to be hooked up to the single coax on the Bolt even though the OTA and Cable use the same frequencies?

That is the point of the workaround suggested, as explained in the linked and quoted information above.

Maybe explaining how things are wired will help sort this out.

From Outside into apartment Coax from Spectrum. In wall LARGE splitter splitting that into 4 locations. 1 Location has Cable Modem and eithernet to Coax/Moca adapter so that the internet from the router which is connected to the cable modem goes back onto the coax that way all rooms can get internet via Moca.

Coax where BOLT is plugs into coax wall where it get signal from Spectrum as well as from Moca. I do have a filter also so that the Moca doesn't leave the apartment.

One thing you haven't detailed is where the antenna will be physically located and how its signal will be routed to the BOLT location.

with the Bolt I have a mini device in another room that I'm able to watch cable off of the cable card in the bolt wasn't even thinking but would this be possible to watch the HD Antenna TV on that mini device in the same manner?

The Mini will continue to function as it does now, receiving tuned content over the home network from the BOLT.

the diplexer at like $10 seems like the cheaper route unless there are drawbacks to this.

No drawback I can recall, at present.

The recommended diplexer can be had for sub-$6, or 2 for under $9.

The BOLT sits in the living room in my apartment near windows and a door to the patio. (4th floor) Do these Antenna's work inside I will I need to put it outside on the screened patio?

Looking into HD Antenna more it seems like direction will be important and may be a problem for me. My patio faces the north and the stations according to the map I saw all sit to the south, I have no way to put an antenna that would face the south.

If you can't do an in-room antenna, the diplexer workaround can be adjusted to allow for connecting the antenna signal at another location, depending on what's available. (see attached for examples)

While not always possible, an outdoor antenna will nearly always outperform an indoor antenna, as the latter has to overcome signal path loss from building materials, etc. There are outdoor low profile models that can mount on a patio railing. Antennas love fresh air!

Also, if you're in an apartment, you may want to check around to see if your building/complex already offers an antenna connection. (Humorously, after I'd spent a day making a homemade antenna, I rediscovered a wall outlet that I'd ignored for years and found that it gave me full antenna coverage for my area.)
