Hi have you tried your TV at home ? If it works OK at home it is obiously a problem with the ariel,even the site boosters can have a poor conection . I think it is a matter of trial and error,try asking your neighbour what his reception is like or even the warden.I doubt it is the TV thats wrong and somehow caravan ariels ,and site boosters do seem to be tempromental .Sorry i cant be more positive.
