We are looking for a solution to get UHF in a second room. An indoor splitter and running cabling to supply a second TV is an idea but would prefer not to have wires running between the two rooms which are a hallway apart if possible. 

I have read up some old threads but have a few questions about indoor UHF aerials.

I have already tried VHF bunny ears but this was not successful. However I know our house in Dunedin has direct LOS to the transmitting tower hill. 

1. Does LOS refer to the property you are trying to receive the signal from or the antenna itself? ie. Does the antenna need to be pointing out a window directly at the tower? Or does it just need to be inside a house that has LOS?

2. There seem to be three "UHF indoor aerials" on the Dick Smith website. Some "powered". Which are "better? Are there problems that powered ones can introduce? I read some suggestion of this but it was not elaborated on. 

3. Aside from the DSE $40-60 options does anyone know of any cheaper options?

4. How much would a 10-15m coax cable to extend the current aerial signal cost to buy or make?

5. Any idea how much it might cost a aerial installer to split my signal and create a new wall outlet in the second room?

Any answers would be much appreciated :)
