You need a way to get DC power to the amplifier.

That power inserter feeds the required DC up the coax to the amplifier.
One port passes DC, the other blocks the DC.
You need to attach a 12Volt 'wall wart' power supply to that black connector on the power inserter.
(Obviously you'll need to ensure the correct polarity.)

The Holland LA-520 amplifier doesn't even come close to a .7 dB noise figure. It's much higher than that.

Based on what I see in the photo below, it looks like you connect (the unit below) directly to the scanner ("To TV"), run one cable up to the amp that sits just below the antenna, and that's it with no need for a "power inserter" as per your photo as the PS-10 IS a power inserter.

Yes/No?!?!?!?!

I feel like I'm losing my mind! lol

You still have your mind.

That does exactly the same thing as the other setup.

Don't forget that you STILL need to use a DC Block on the other side of the amplifier to keep the DC from getting to the antenna.

The LA-520 is intended for satellite systems where there are amplifiers built into the dish.

The LA-520 'normally' would pass the DC to the dish. In a scanner setup, you do not want that to happen.

Thanks for the clarification Rich!!!!!

Now, can I use a regular DC block like this one VBC In Line Coaxial F Connector DC Voltage Blocking Coupler or would you suggest another unit?

 

[rbm]

That unit will work just fine and it looks like the price is right.

HAPPY DAY

Thanks for sticking with me on this one Rich, I REALLY appreciate your time and attention!!!!!
