torroidal vs. motor

I'm trying to decide between a torroidal dish & a 90cm + motor. As I
understand it the advantage of the torroidal is you don't have to deal with
a motor (noise, reliability) and easier alignment. The disadvantage is you
need an lnb for each sat you want to get which can add up in a hurry. Is
that about it?

is. What blindness. What unintelligent leadership. A scurrying mass of
bewildered humanity, crashing headlong against each other, compelled by an
orgy of greed and brutality. The time must come my friend, when this orgy
will spend itself. When brutality and the lust for power, must perish by its
own sword. -Lost Horizon, 1936

I would suggest that an installation on the torroidal will be more difficult
and time consuming than a motor. We install motors in 30 -45 minutes. I
rarely ever noise the slight sound of either of the motors, one on the side
of the house and the other on a ground post mount. Been running a SG2100
with a 1.2 meter Channel Master (as a test for wear) for over eight months
now with daily multiple moves without a glitch.

Instant switching on a (one?) dish solution is a benefit, but you also
confine your choices to 40 degrees of the arc and the adding cost of
switches and lnbfs.

You are also somewhat limited as to how much of the Clarke Belt you
can get with a torroidal dish. You'll never get 120 degrees of the
arc unless you're talking about multiple torroidal dishes. Then
you're really talking about some serious jack for LNB's.

Take care,

Another issue to consider is the minimum spacing permitted on the
toroidal. Depending on the model, I've 3-5 degrees. If you have two
birds a couple of degrees apart, you can't mount the LNB's close
enough to get both.

Polarization is also an issue. You will need special LNB's for
circularly-polarized birds.

I've been running an SG2100 from my Pansat 700HC for a year now
without a problem (two moves a day, programmed). It IS true that
changing satellites is not instant, and I'm limited to a single
receiver control (only one bird can been seen at a time). A toroidal
offers the possibility of multiple receivers/multiple bird.

Good luck.
