Also is there enough programming options from using just either one of the satellites
Yes. I have a Patriot 85e dish with an Pansat 5600 LNB pointed at Anik F2 only and it works just fine, as I am interested only in French.
In general, HD and French comes from F2, English comes from F1R. There are some exceptions though. Here's a good guide:
The channels that are colored green in on the above pages are HD.
You can also use two generic dishes like mine connected with a switch in lieu of the standard Shaw dish if you want to get your full package.
I have a few people calling with eliptical dish
Be careful with this. The Anik satellites are approximately 4 degrees apart in space. The distance between the "little white circles" on the LNB is critical to proper reception. If you purchase a third-party dish with the hope of receiving the Aniks, be sure that
the LNB they sell you will work for 4-degree satellite spacing. I know there are some out there, but I've not heard how/if they work with Shaw. Such LNB's require a special manufacture.....if you examine a standard Shaw quad LNB, you will notice how the "circles" actually touch and, in fact, overlap each other. Without such a specially constructed LNB, you will not be able to capture signals from two satellites with a 4-degree spacing using a single dish. And, if you try to cobble 2 LNB's together on a single dish, the physical size of the 2 LNB's will prevent you from getting them set at the proper spacing.
Also, if you go with a third party dish/LNB, be sure it can receive Ku band
signals. This rules out the dishes used by the two American satellite providers.
What is the length/width measurements are they straight across or follow the concave.
Can't help you with this one..... The 75e is nominally 75cm in the horizontal dimension, but as to exact dimensions, maybe some else will respond. But, in truth, it's not the exact dimensions that are important. The size of the dish determines how much
signal it can capture. The further south you go, the weaker the signal, the larger dish that is needed. For Mexico, anything in the neighborhood of 75cm & up should get you enough signal.
If you want to purchase a 75e (don't buy a 60e for Mexico, it's too small) sent me a pm. I can recommend a vendor in Montreal.
