Need adapter for 12V to Coax power input

[szoostrom]

I'd like to power two RF amps (Channel Vision model C-0310) from an existing 12V power supply, instead of the "120V AC-> 12V DC over coax" brick transformer that comes with these amps. Is there an adapter available that goes from two wires to an F-connector, allowing me to use the existing power supply ?

The reason - I'm setting up a video cabinet that will have connections to security cameras and antenna TV. The cabinet will already have 12V DC power in the cabinet for cameras and a modulator. So to keep things organized, I wanted to eliminate the brick transformers.

Any known issues with this modification ?

Thanks for input!

I'm using this to insert and siphon power off of RG-11 running 750'. Works great.

I am not sure how well a CATV power injector will work with a CCTV signal. You may want to look in to this a bit more.

thanks silveradofreak. That looks like the thing I need. I'll get one and test to see if it works as I think it should.

You can inject DC with RF and use a DC block on the ends. It should not cause any issues. That is how line powered amplifiers work. I actually use it to charge a battery and the DC does not affect the RF at all.
