I'm not familiar with exactly how they work. As you can see, the powerpack feeds 1 input and the other output goes up to an antenna selector, some switches and then the other TV outlets. Don't know much more than that, I'm not an expert on this sort of stuff. I did pay for a professional to have a look but that was a complete waste of money, so not going down that path again. I rather just try to replace the powerpack to keep costs down. TV in our house has cost heaps over the last 4 years, not wasting too much more $ on equipment.

See what you can find here Antenna Amplifiers and Boosters for Digital TV - Academy TV Australia or contact them and they find or make one for you.

... My device is 72 watts.   

If yours is anything like the same size as this one, you'll be a long way from 72W, which is why I'm inclined to believe your supply is delivering 300mA, already twice what the first linked device does. A 72W supply would look more like a teenage P-plater's sub-woofer amplifier, probably the size of a large breadloaf and with a black anodised heatsink chassis!

I've got one of those.
