Our Burstner T Star came with a Camos aerial (lump on the head) and Maxview receiver. We installed new Cameo TV 12v and booster box. all worked perfectly for 2years but now the aerial isn't speaking to the receiver or vice versa. Have telephoned Maxview direct and several suppliers up north (We're in Cumbria) and can't get anyone to even look at it. Any suggestions please?
