I have continuous coverage at Corro on an iPhone, as long as I am not behind a car of phone in pocket, then it is say 70%. its line of sight to Gero foreshore once you are a couple of meters up - if a judging scaffold is going in the same place as last time I would be sure of continuous coverage as you will have the gear 3m higher
If not, ask Mathew- tech extraordinaire and Telstra man? If he can't sort it nobody can...
