I'm living in Geelong and not used to having bad reception. The place I just lived in had some kind of boost device plugged into the wall tv connection, so I got a perfect picture and the arial was high up (second story). The new place in Geelong has a shorter arial on the roof and I cannot get any signal except a very poor ABC. I've tried both with and without set top box and no signal. Is it easy to fix if I buy some kind of device to boost the signal? I have seen some around. I've just never had this experience of no tv signal...I think the signals come from Melbourne so that is why, but can i fix this?? I'm renting so I can't really install a new antenae on the roof.
