Just purchased this at a warehouse sale.... new in box

84cm dish made by channel master
back part has skew adjustment
feed arm with 2 dual lnbs attached (lnbs look like regular starchoice ku
band type)
mount


what can this dish be used for ?

what seperation are these lnbs ? is it simular to star 3.8 deg ?


any help, or comments is appreciated....

Ron

ps, lnbs are marked A and B

Well, I'm pretty sure it's not a PrimeStar dish.

More than likely, it is a StarChoice dish, but I can't tell you
for sure without a picture.

It can be used for any Ku FSS satellite, probably.

Doesn't sound like anything we use in the US.
Post a picture.

Sounds exactly like an old Primestar dual lnb elliptical dish. 2 "beer
can" lnbs marked A & B. Each lnb having 2 F connectors providing horizontal
and vertical outputs. These lnbs are mounted via
WR-75 flanges to the metal feeds attached to the plastic mount. General
consensus is that the lnbs are linear Ku(?) and with the addition of a 22khz
tone switch or Diseqc switch could easily be used with a current FTA
receiver to view both polarities.
Primestar is dead and gone, so they're no longer in use for that purpose.
But the hardware is still usable. The lnbs are plentiful, and since they
mount on a WR-75 flange, you could get a feedhorn and mount it on just about
any offset or elliptical dish that would accomodate the feedhorn diameter.
Thousands of these units were in warehouses when Primestar ceased to exist.
So it's no surprise that liquidators are selling these new-in-box. Patriot
was selling them too.
I don't know which 2 birds these rigs were supposed to look at. Who
bought out Primestar? Was it Dave or Dish? Or either? I'm inclined to say
Dave, cuz when you see one of these Primestar rigs aimed off into the trees,
you're just as likely to see a DTV dish mounted nearby. Dave is known to
give away hardware to hook a subscriber anyway.
Another use for the dish, would be to remove the plastic bracket holding
the 2 lnbs and replace it with a CalAmp or other rectangular style mount DBS
lnbf. Use a slightly longer screw with a wing nut, and you can clamp the
lnbf in place. No drilling or mods required. The larger dish could improve
rain fade performance, or if you're on the edge of a bird's footprint make
the difference in receiving a signal or not. I use mine for Nimiq-1 here in
South Louisiana. An 18" DTV couldn't gather enough signal. Same lnbf on the
84E, and I'm in business.
With some imagination and ambition, I'm sure there are other
possibilities as well. Good luck with your application.

Ron,
Other than the plastic cased lnbs, your dish setup is as I described
earlier. Usable stuff. But how you'd use both lnbs aimed at 2 different
birds is a mystery to me. As I said, I don't know which 2 birds that rig was
designed to view. Thus I don't know the separation between birds. Channel
Master also made the old DirecPC 75cm elliptical dish. That setup viewed 2
birds with only 2º spread. As you may already know, the current Phase III
DTV dish sees 3 birds in an 18º spread. Point being that without knowing how
much separation your rig was designed for, how ya gonna aim the dish to see
2 birds? Which 2 birds? If the figure of 3.8º mentioned in an earlier post
is correct, I think I'd round up to 4º and try for example Telstar-5 @ 97º
and AMC-4 @ 101º. Offhand and without checking Lyngsat or Satco, I'd think
that combo would yield the most viewing potential.

Good luck
Mike H.

BTW---To those who would point out that T5 is no longer T5... Telstar is a
name from many years ago when commercial comm satellites were first deployed
into space. That's roughly the same era as the Mercury and Gemini missions
taking men into space. In spite of current ownership of the birds, I'm not
ready to let the Telstar name go yet. In this regard, I'm an old fart.

Here's what you need to do to figure out the angular spacing:

1) Measure the distance from the middle of one LNB to the other.
In your last picture, you can just put a ruler over the LNB
clamping brackets (the round pieces with the scale marked on
them), and measure the distance from the gap in one to the gap
in the other.

Call this distance 'a'.

2) Measure the distance from one LNB 'eye' to the middle of the
dish.

Call this distance 'b'.

3) Calculate:

angle = 360 * a / (2 * 3.14159265 * b)

4) Report back. We're curious.

Wow, that is a cool feed horn. It does look like a PrimeStar, but they
never used a dual feed system. DirecPC used the same mold for the gray
dish in the old days, but the 95/101 arraignment looks different than
that. I suspect the feedhorn is aftermarket, if you are really lucky
it will hit 105 & 121 at the same time.
Is this dish new? It looks like the sticker got weathered off the
dish. The shadow looks PrimeStar to me.
A spectrum analyzer would really help you align it.

Primestar was on W3, quite high here. With the offset of the dish they
all looked like they were into the trees. DirecTV bought them out and
provided all the current subs with DirecTV equipment. Fun days, a
conversion paid $80, took ten minutes and you got a cool Primestar
dish and IRD if you wanted it. I still have a stack of 1.2's and non
pen mounts in my back yard
As far as I know, they never used or even considered a dual beam
system.

ok will do, the dish to lnb measurement.... where on the lnb? where the
grey
meets the brass? Ron

Hi Again....

here are the measurements:

lnb to lnb ...2-7/8 or 2.875
center of dish to lnb 24" (measured from center of 4 holes in pan to where
the grey meets the brass on the lnb)
my calc gives me 7 degrees ??

this dish was brand new in the box when I purchased it

box also has model no. " WSNET DSK410DS "
combo box w/ .84 dish, dual feed, 2lnbf, pole mt

thanks again,
Ron

Where the grey meets the brass is perhaps a little too far; I meant to
the front of the eyes (feed horns). In any case, it won't change the
answer by more than 1 degree.

If we assume the spacing is 8 degrees, then you can use this dish to
get T5 (97) and AMC2 (105) [Dish Network] at the same time. Getting
105 only helps if you have a Dish setup and you need the locals on
that satellite. (Dish's sats at 105 and 121 are Ku FSS; their others
are DBS and wouldn't work with this dish's LNBs.)

If there's not 2 satellites 7-8 degrees apart that you want to get,
you can always use it as a single satellite dish. Just set the skew
to 0 (horizontal or level) and aim 3-4 degrees off of whatever bird
you want to get.
