800 mhz mobile antenna for indoors

[tolley]

I recently acquired an extra 800mhz mobile antenna and I would like to use it indoors preferebly mounted in my attic. Do I need to use any metal for the ground plane and if so how big? Also, what kind of cable?

There is a plethora of information right up this alley in this forum already asked and answered many times.

Chances are you have a Motorola NMO mount type. Not a cell phone type. If you get an NMO L-bracket to mount it on you really would not need ground elements because you are not transmitting. Use RG-6 with "F" connectors and an "F" to BNC for the scanner. With RG-6 you could add a splitter or A/B switch.
