I can't say for sure, but my guess is that you would have problems getting it to sit at the correct focal length with the mounting hardware that that dish has. Ie the Corotor has holes on the rings, that you bolt to 4 feed arms, but the hardware on the above dish only has 3 arms, and the odds are good that they wouldn't put the feed at the proper distance from the dish. It's possible that you might be able to connect that hardware directly to the horn tube, but the rings are so wide on a corotor, that I'm not sure they would fit inside the 3 mounting arms, particularly if you got it at the right FL, which I doubt. You might also have problems adapting that dish to normal BUD polar mounts.

Also, why do you have a polar mount, but no dish? Was the dish damaged? What kind of mount is it? Some BUD mounts can easily be adapted to handle different brand dishes, while other mounts are pretty much part of and specific to the dish.

Also, what kind of receiver(s) will you use? Ie if your mount is a typical BUD type mount/actuator, most FTA receivers won't move the dish, unless you get a separate vbox to translate the DiseqC and voltage signals into something the actuator can understand. However I don't think that the VBOX solution will handle the polarotor on the Co-rotor feed, and a normal FTA receiver won't handle the polarotor on the Corotor. Ie the best way to control a regular BUD style actuator and a Co-Rotor feed, is to use a regular analog IRD receiver, and then slave your FTA receiver to it.

Also, you say you have a Co-rotor, but don't mention whether you have LNBs installed. If you have to buy LNBs for the feed, that can add up to more than the cost of a C/Ku lnbf. The CoRotor is a great feed, and I highly recommend the adaptability of going that route, however it is a much more expensive route, depending upon what you are trying to do, and you are better off slaving to an analog receiver if you go that route.

If you are not goiing to use this unit with your new dish I would be interested in purchasing it from you. Providing you have the lnb's also. As to controlling the servo motor. A Pansat receiver I am told will do that but Sadoun does not sell them and they are a bit more expensive. Coupled with a VBox I believe some of the issues Bill addressed would be handled.

The company call me and told me that the fortecstar 180cm dish was much better dish than the sami 6ft mesh dish since the fortec is a solid dish.i told them ok send me the fortecstar dish instead.When i received my order yesterday it had everything i listed except the corator 2 and the .6 and .17 lnb.They replace this with a
BSC621-2 C/KU Band LNBF which i think is a joke for ku/cband reception.I already have one on a channel master 1.2 dish and the ku reception is 30 points lower than what get on my invacom QPH031 lnb which is not acceptable.I think i was given the old bate and switch.The fortec 180cm dish they send me looks very cheap compared to the sami 6ft dish.I think i am going to send the whole thing back since i did not receive what i ordered.Sorry about the blue fonts.I think i hit the wrong button on my computer.

I used to have a SAMI dish, and it was the best dish I've owned, although as with most companies they sell several different grades of dishes, plus the one I owned was a 10' or 11' dish. Some people don't like mesh dishes, but I think that you can get quality mesh dishes just like you can get cheap solid dishes. I think the fact that they switched the corotor for a LNBF answers your first question.

Interesting about the polar mount on the Fortec. I went to the Fortec site, and couldn't find a polar mount version of that dish.

It looks like the original system you tried to order had compatable components, but it looks like what you got isn't compatable with itself. Also note, the orb analog receiver is probably not completely compatable with the BSC621 LNBF either, see recent topics which discuss not being able to reach all Ku transponders due to the 10600 LO freq.

Myself, I would have been much more comfortable with the SAMI/Corotor system than the Fortec/BSC system, not to mention that the SAMI/COROTOR system is probably worth 4 times as much. I hope they charged you a LOT less for the substitute system?

[elgemcdlf]

You had a decent system going. I do think they took you for a bit of a ride though. In concept a solid should be better for reception that a mesh of equal size providing the solid is a single piece unit. You should have got a huge refund with that feed switch they pulled on you. Not to mention the issues you listed along with what Bill stated.

In concept, the material doesn't matter, since to microwave mesh IS a solid. What matters is how perfect the shape is. A solid can be out of shape just like a mesh can. The bad thing about mesh dishes is that they can be bent out of shape up easier than a solid dish, like I've done with my broom every winter. But if I was going to buy a new C-band dish, it would definately be a mesh dish. I wouldn't consider a solid dish for a second. And that's mainly based on cost, both cost of the dish, and cost of shipping. Dollar for dollar, for a C-band dish, you can't beat a mesh dish. If money is not a factor, then perhaps it's a different story.

[elgemcdlf]

The company I work for has 10 plants and a couple distribution centers. While shipping might take awile (until space is available on a truck coming this way) the cost is very acceptable (free) If mesh were a solid to microwave then hole diameter would not matter Sadoun would sell 1' mesh dishes. We will most likely always differ on this particular subject because I just flat prefer solid one piece dishes. The bigger the better. But cost wise I am getting 8.5' mesh dishes for free pretty much anytime I want one. That is why you find mesh dishes in my yard. The last solid one I got was 10' but warped by the folks that took it down. They didn't want it anymore and did not care how it came down.

Yes you can .

Oh by the way, you did not order this from us did you? we don't sell the Polar mount type 6' dish. Also, we don't bate and switch. Just to make this clear so people reading your post don't think we did it for you.

Unless you're buying a 20 year old mesh dish, hole diameter really isn't much of an issue. Any recently made dish has a small enough spacing that there is very little loss. I just went out and measured the mesh size in my two mesh dishes,{about 4mm spacing and 2mm diameter) and used a nomagraph which calculates gain loss due to signal getting through the mesh. I may well have made some measurement and calculation errors, and welcome corrections, but I came up with about a 2% loss. I'd suggest that there is much more loss due to non parabolic (or eliptical as was suggested to me in another forum) shape of the dish, regardless of the material. My mirror experiments is enough to convince me of that. Basically, the wavelength of KU is about 12 times the size of the holes in the mesh.

Solid dishes CAN be more stable relative to shape and CAN be more perfect in shape, but at a high expense for big dishes, and stability means little if it's not shaped right in the first place. Plus, for a big dish, solid means weight and means low velocity wind problems (at high wind speeds a mesh dish is just as bad as a solid dish), both of which means a more sturdy mount is requirred, meaning even more expense. I still say that I'll live with the 2% signal loss, and save enough money on the dish to buy a bunch of receivers.



I think the reason you don't see Sadoun selling 3' mesh dishes, is that for small dishes I'd guess that it is probably cheaper to construct a solid dish, since it is just a single stamping operation rather than constructing a grid and placing a mesh on it, but for big dishes it's cheaper to construct a mesh dish for several reasons.

One thing is pretty certain, and that is, given a good quality mesh dish and a good quality solid dish, there will be little if any difference with respect to what channels anyone on this forum will ever receive.

No i did not buy it from you sadoun.Your service is top notch.This is the new polar mount fortec 180cm dish.I don't think its been out long.The dish is the same one that you sell FC06 except it has a polar mount.I contacted the company that i bought it from and they said the distrubitor mistakenly sent me the wrong lnb.They shipped the Corotor feed horn and the cband and ku lnb out to me today.They email me a tracking number so i guest everything will be okay.They also sent fedex to pickup the other lnb he sent by mistake.They told me the Corotor C/KU feedhorn lnb they are sending has an adapter to make it fit on the fortec 180cm dish.Sadoun have you ever seen the FC06 with the polar mount?Again i did not buy the dish from you and your service is always top.If you sold the polar mount 180cm dish you would have been the place i bought it from.The forum has convinced me that the sami 6ft dish is just as good or better than the fortec but if the corotor feedhorn will fit on the fortec polar mount as they tell me I think i will be okay.I bought a complete setup with my order analog recevier dvb mpeg receiver.I don't really need the viewsat extreme they included in the package because i already have two fortecs i bought from you and they have great blindscan capability.
