How did you remove (and reattach!) the back cover?  There's a shitload of
thermal mass there to overcome.  And, over a large area (2+ sq in).
I'd be tempted to try a propane torch for removal -- in the hope that
there would be no collateral damage from the excess heat.

Powered splitters/amplifiers tend to accept power over an F-connector.
It's all low voltage (9-15VDC) and low power (a few watts).

Providing power by connecting several RG6 "stubs" together and to the power
source doesn't change the amount of power or potentials involved.

It just looks more "homemade".  <frown>
