[time-nuts] Low-cost GPS distribution using DVB-T parts?

Folks,

I wonder whether anyone has tried GPS RF signal distribution using 
low-cost TV parts?  For example, this amplifier:

  http://www.amazon.co.uk/gp/product/B001AI7OOQ

is rated up to 2.3 GHz and could be driven from the +5 V available on the 
antenna socket of some units.  Used after a puck antenna, its noise factor 
would not be critical, nor would the 50-ohm/75-ohm impedance mismatch. 
You could then add a 2-way or 4-way "satellite TV splitter" to feed 
multiple GPS units (taking care of the DC paths and various connector 
formats, of course).

Just a thought....

Cheers,
David
