I have a extra cal-amp 5 LNB pack but I will not get lose it because I have had one fail and will not wait on protection plan to come replace it so I keep a extra one on hand (and the zinwell 8 output multiswitch) so I can be back up in minutes and trade the broken on to the tech when they make it out in 5 days. The tech said the cal-amp is not available at "retail" anywhere. Why don't you just have them replace the LNB unit?
Success I hope. Thanks for the inputs. They are hard to find but several phone calls and e-mails finally lead to a good source on e-bay. I agree with the comments above but have a special "project" that I wanted to experiment with. Since the Cal Amp version has F connectors between the main and side arm LNB housings ; a "Line of Site" issue might be addressed with 2 cal amp dishes and connect the side arm of dish 2 to the main LNB of Dish 1. I want to see how far apart they will work. I've read that the old way of multiple round dishes will not work since the Ka signals are stacked in the main lnb housing. I haven't expeimented with the flex ports of a zinwell multiswitch.
