Elliptical Dish-wow!

[bloomdog]

I just set up my new Channel Master elliptical dish (36" high x 24" wide) and it's reception is just as good (so far) as my 1.2 m Channel Master oval dish! I also bought a cheap 36" oval dish (thin metal)-what a piece of crap! Can anyone explain the excellent performance of the elliptical dish v. the significantly larger oval dish? Also, I have learned that quality really matters--quality seems to be more important than size (no jokes pelase!!).
Thanks for some learned input.

I'm finding the same thing, I"ve had quite a few dishes and I think the best dish I've had, at least for keeping an accurate parabola shape is a fortecstar 76cm. The others have warped, some as soon as I tighten the bolts on the dish bracket, some warp with the sun on them over time. Every dish seems to be a compromise of something. Can you tell me, where did you get that Channel master elliptical?

 

[bloomdog]

I got it on eBay for $11 plus $50 for shipping. Well worth it--came with a nice, strong mounting Channel Master three-legged mounting bracket, a Channel Master AZ/EL mount, all the hardware, 75 feet of R6 video cable and a nice lnb (Norsat 2707A). The guy a bought it from apprarently bought if for internet satellite but went to cable modem and had no sue for it. All in new conddition in original boxes!

You got a steal of a deal! I think those channelmasters are better dishes because they hold their shape, maybe the elliptical shape is easier to maintain than oval or round. They look like they are heavy, do you know what your's weighs? Also, do you have it on a motor or stationary?

 

[bloomdog]

I just got it so I haven't put a motor to it yet. My guess is that the dish alone weighs about 10 lbs. It's Channel Master part no. 3041221. Sadoun sells it: http://www.sadoun.us/Sat/Products/GlobeCast/GlobeCast-Elliptical-Dish-LNBF.htm

I have one of those for my StarChoice setup. The dish is pretty light compared to other dishes

Equal LNBs?
Equal receivers (or the same one, of course)?
Equal experience in setting them up (you are more seasoned, now)?

For a more fair test, maybe you should go looking for some really weak transponder, and then see which of your Channel Masters does better.

although i don't think its impossible to motorize (and i don't have one to try) . these dishes are newer design and have a lower mounting point than the older primestar/channelmaster dishes.

heres a photo of one of my primestars and you can use the link above to look at the globecast/channelmaster dish. The globecast/channelmaster dish will show a lower mounting point for the skewable mount. so lower mount & lower holes for the bolts (i don't even see bolt holes for the higher mount on this dish) so they might have been covered/filled.

the primestar/channelmaster dish mounting point is in the center of the dish.
with the globecast/channelmaster mount being lower i don't think it will track the arc correctly on a motor. but untill someone tries it, this is only a guess

You can't motor an ellipical dish?

Nope, is not possible; See below.

I have one of those Channelmaster elipitcals. One of the things you will have to worry about is the weight. Some members here who have motorized their primestar dishes had to customize the mount to shed some weight. I believe that my dish (inc hardware) weights about 31 lbs (same weight as my Fortec 120) In addition, I was trying to motorize it with my SDM312. Putting the weight issue aside for that motor, I was having problem mounting it using the existing hardware. The elevation that I needed for my location wasn't possible. A HH120 or HH100 mount (upright motor) would have worked.

Read some of the post about motorizing a primestar dish. It should work verbatum for the channelmaster.

I would like to mount my Channel Master elliptical dish to a motor--see Thread No. 1 above--since the mount on the back of the dish is lower than center will I have trouble following the arc? DO I need to build an adapter so that the motor will mount to the dish at the direct center of the rear of the dish??

 

[gabshere]

your in uncharted waters here i know sadoun says no
i think since the mount is now lower that it probably wont track the arc but the only way to find out is try it . if you already have everything.
you have the globecast dish with lower mount right .....do the holes for the center mount go all the way through , the new lower mount looks like it remakes the lower two holes and adapts the new skewable lower mount . if you was close by i'ld just let you try one of my old primestars

I recently mounted my Channel Master Primestar 84E to my HH100 motor. Used the original mount - the only minor modification was a $2.00 piece of PVC pipe that I used to shim up the shaft.

Works great - tracks the arc perfectly. Here are some pics:

Yes, but it looks like your dish mounts in the center of the dish--the problem raised in the threads above is that some dishes have mounting points lower than center. Has anyone had any sucess motorizing the dish shown below?
