richms: Does NZ have any laws that stop property owners from preventing the install of FTA antennas?
i'm pretty sure its either illegal, or expressly forbidden by contract/lease, to run cables through walls or affix structures to the building without the landlords express permission. In many leases you're not even allowed to affix a painting or photograph to an internal wall..
NB: As a landlord I *want* to provide the Sat Dish and UHF aerial - i've seen too many cowboy sky installers with big drills and little care! The cost of these installs - usually $500 +/- is much cheaper than the fix if you end up with damage down the line - especially in those leaky building scenarios.
