The 60E and 75E are the models of the two current produced dishes from Shaw Direct.
The 60E is the smaller of the two dishes, oval shaped and at its longest point approximately 33" Across. The 60E uses the standard J-Pipe Neck size and works througout Canada generally without issue.
The 75E is the larger of the two dishes, also oval shaped and approxitmately 37" across at it's longest point. The 75E is not commonly used, as the 60E is generally suiatable. The 75E is used where signal may not be as strong, such in heavy cover or the southern states. Please be aware using Shaw Direct in the USA is against their ToS.
