Hi all, I'm after some direction as to which direction I should be pointing both the UHF and VHF aerials to pick up their respective signals. I'm after the Hamilton alignment bearings/info if possible.

Can't seem to find them on the net as Im guessing they are mostly used by TV Aerial installers - but true to being a bloke I'd like to have s stab before I pay a professional

Any info would be appreciated!

Thanks

I am not sure about Hamilton...

But if you are wanting to just 'give it a go' then stand on your roof and see where everyone elses is pointing.

Stand outside their gate with a cheap compass, and move until it points in the direction that theirs is pointing.
Then go onto your roof and using the compass, point the aerial in the same area.

Hi, TV 1,2 Sky, Prime and Maori come from Mt Te Aroha (VHF set Vertical and UHF set horizonal), TV3 and C4 come from Ruru Hill which is near Morrinsville. I notice most people have a combo VHF I/II aerial pointing at Mt Te Aroha so I assume they are getting good TV3/C4. Freeview (Digital) will be on Mt Te Aroha also.

Thanks guys - will have a play. Mt Te Aroha is a good direction to start with!

Failing that - those electrically minded - a rough signal tester could be made with what?

A typical tv antenna when running in vertial is very wide open to being off axis and getting signal, which is why ghosting is such a problem with vertical transmission. You should be ok just slapping it up in the vague direction of tearoah and then you will need to trial and error to nul out any major ghosts - thats something a basic signal meter doesnt help a great deal with.

If you have line of sight you should be ok tho, but if you still have issues, then just put up a uhf and wait for freeview ;)

Try this website, it was extremely usefull when I was setting up my Media Portal Software.

I realized after posting this link that it doesn't include direction or angles, however I'm sure it still might be usefull.
