[mythtvnz] The Number of Sat Channels Available in New Zealand

[Noel & Di]

The toroidal dishes take alot of fiddling to get them right and their 
signal gain overall is not stunning.  I have found they don't perform as 
well as two seperate 76cm dishes with two LNBs on each.  If you want to 
watch channel-at-a-time and play at feed hunting, go for a rotator like 
the Motec - a good little unit, but do spend the time accurately setting 
up the mechanicals ie the mount MUST be vertical within an Nth of a 
degree and your elevation and declination needs to be spot on - will do 
a post for you soon on that. These links are a handy referance in the 
mean time.

But if you want to use your setup to watch one sat & record another sat 
(esp if they are different polarity signals) I would suggest seperate 
LNBs stacked 2 per dish. (or two rotators of course).  Dishes- bigger is 
better :o)), go for 60 - 76cm if you want to look at Mac TV or Arirang 
(you can get D1 on a tiny 40cm dish) or get a 1.2m if you're going to 
look at C band feeds. Me - I use a 76cm on a Motec for everyday PVR use 
& I have a 3.1m solid with an actuator for feedhunting which is also on 
my PVR.
