I'm in a conundrum in regards to whether or not I can get FreeviewHD or not. 

I've recently purchased a house in Kelson, Lower Hutt and wasn't sure if I could get FreeviewHD. I've purchased a Pinnicale HD USD TV Tuner to test before dedicating more money to the cause. 

I can receive 5 channels and just get an occasional frame from the reception on the tuner with the small 100mm aerial that comes with it (when on the roof). 

I've tried connecting the USB tuner to our aerial setup, but I have a feeling the system is either wired up badly or the amplifier it is going through has burnt out. It passes a continuity test with my multimeter so there is connection termination from TV to aerial. 

I'm just wondering if it's worth even trying to get a new aerial system and then trying this out. 

Any help would be appreciated..
