Has anyone used an integrated coax amplifier/splitter (1x6) that worked to pass MOCA between the 6 splits?
Care to share what works?
I have very limited room to work with. Everything is jammed into a 2G wall opening.
I may be schizophrenic, but at least I have each other.

PCT makes one that is MOCA compliant on active ports, does not work on the passive EMTA port. However they make another that MOCA works across all ports so verify which one you need.
Sorry did not pay attention to the two gang part. You can use one of their one port amps to boost incoming signal. Any of their splitters as most are MOCA compatible so long as they pass over 1ghz. Dont forget your moca filter on the input side of root splitter to help overcome port to port isolation of splitter legs.

These may be stupid questions because I am only now looking into the details of MOCA.

PCT's site shows seven amps with the word MoCA (as they write it) in the title. All of them are amps that have MOCA filters integrated into them. Two are amplifiers and five are bypass amplifiers.

Which ONE amp did you have in mind? Can one just take an appropriate amp and add the MOCA filter to it, which PCT also has?

Does this mean any splitter that passes over 1 gHz is MOCA compatible? How high over a gig does it have to work?
A good answer is easier with a clear question giving the make and model of everything.

MoCA is the correct way of typing it. As it stands for Mulit-media over Coaxial Alliance.

MoCA uses the 500MHz to 1,650MHz. The frequency used is dependent on the application. Cable companies typically use the 1GHz or above for the MoCA area. While satellite uses the lower part, as the 1GHz range messes with the feed from the dish to STB.

The modem bypass port is not amplified so an EMTA would still receive signal if power was interrupted. However if you had an access point on an active or unity gain leg, on an existing line going to a cablebox the emta would not see the access point. So the new models came out. The ones with the red box and wording on the front. Where that problem is solved. Sorry exact model numbers are too much for me now. The MoCA filter is still needed. The wording is misleading and recommnded to still use it on the rf input. Try to give so more info later. Quickly some of the amps are unity gain, just making up for internal splitter loss and some provide additional gain.

I honestly don't understand why the passive port is even being mentioned here. It shouldn't have any affect on passing, or not passing MoCA.

Granted, if the power goes out. Then the device that is connected to that port won't see the other devices via MoCA. But at that point, why would you care... The power is out. However, if the client has a backup for power... Then the installer shoulda installed this amp on a backup circuit as well.

The passive port is obviously for emta's with battery backup so a phone could still work assuming you have a non cordless phone. Problem with the past model amps was that port would never see MoCA APs. You had to run a new line and put the AP on a splitter with the EMTA or modem. Now you can put an AP on an existing coax that has a cable box on an amplifies leg and it will see the EMTA. Of course you could put every device on the active legs if you choose. Oh and with the cable companies whole house DVR the EMTA or modem becomes the, forgot the correct name maybe it is host of the MoCA network. So you can see why it would be helpful the passive port now works with MoCA as it is a rule they follow not to amplify voice.

The passive port/amplifier setup matters because MoCA is carried on high frequencies. Cable return path frequencies are typically below 100 Mhz, MoCA frequencies are well above that (one design band between 400-700 Mhz, others above 1000 Mhz.)

The EMTA port is upstream of the amplifier in these devices. Whether by accident (just doesn't work) or design (actively filters out) the amplifier doesn't propagate back frequencies above the return path, neither the EMTA port nor the input port will see them at all.

These newer models have apparently been modified to fix that. I've also seen suggestion online that they have been changed to better propagate the MoCA frequencies between the amplified ports, which earlier designs may not have done well, especially for the higher frequencies MoCA 2.0 uses.
