Re: [Equipment] How can I run 650' of cable from my house to my MoCA over RG11. You could probably get away with RG6, but I wouldn't risk it.
You can send power down the RG11, just make sure you get an inserter that passes 5-2150 MHz. MoCA 1.1 uses up to 1525 MHz, but 2150 MHz is a common inserter frequency that will foot the bill. Make SURE you find an inserter that will pass enough voltage and current to power both the WISP radio and the MoCA adapter.
Quality RG11 will have a 14 AWG center conductor of solid copper, and a braid with 85% aluminum shield.
The DC VD @ 700ft should be about 7-9 VDC @ 48 VDC supply running a 2 Amp load. You'll have to investigate the operating voltage and current of both the MoCA device, and your WISPs radio equipment. You'll want both to be similar. You'll probably have to come up with a special order power supply to get the voltage just right, or at least within tolerance, on the far end.
I've done many MoCA installs now, and can say I've never encountered a problem. It works seamlessly out of the box.
If you wait a few weeks, MoCA 2.0 equipment is supposed to be on the shelves.
MoCA will work to 300 meters on RG6. RG11 extends this distance somewhat.

Or do what cable does and shove 60 volts ac down the coax, then either rectify to the DC voltage needed or use a 1-2 ratio transformer to bring it back up to 120 volts ac and power locally from that.

Also, one needs to keep in mind that in this application two would be needed in bookends fashion, one as the injector and the other as a picker.

1 edit | said by LLigetfa:Thanks for doing the legwork. The DC injector spec'd has a bandpass of 2-1450 MHz. It's worth noting that those devices uses inductive blocking on the DC side and capacitive coupling to pass the RF, as such the label may say it goes to 1450 Mhz, but I am willing to bet it goes higher, the size of the cap limits the low end pass through frequency but as the frequencies go higher it becomes less relevant and mechanical construction becomes more relevant and the design of that device is a pretty simple “T” without a lot of impedance through the RF path as such it’s losses at 1525 should be quite tolerable..
Also with MoCA the additional bandwidth gained in the newer versions is gained by adding channels at lower frequencies which I believe rev 2.2 has down to 500Mhz as such the higher end is not being pushed even higher.
The larger problem I see with MoCA is in the lab it should handle up to a 60dB link loss, but I am quite willing to bet the manufacturers of the devices knowing it is “in home” networking system may be selling devices that cannot handle those loss levels.
As such, I believe the focus should be on keeping the coax losses to a minimum of at least half that 60dB down rating.
