Just discovered today that the actuator broke on my 10 footer.  Motor works fine, it know the limits, but the arm is not coming out of the shaft.  Also I can slide the arm out of the shaft just by pushing up on the dish.  So the internal screw seems to have broken.

Ball Screw vs Acme Screw.  Trying to figure out which one to go with.  My existing one is a Venture Ball Screw type, but they are $100 more.  Only want to spend the extra $$ if it is worth it.  One other thing about my broken actuator, it would always freeze up in the winter, so I want to make sure my replacement doesn't have that problem.  My dish is a 10 foot mesh one.



Don't blame the computer! It does exactly what it's programmed to do!

Definitely go with a Ball Screw 24" arm especially with a boot to keep the elements out.  A Ball Screw is much heavier duty, smoother,  and will last much longer and is worth the extra $100.  

The Venture Ball Screw MA818-B24 that Rick sells is worth it and will likely be the last actuator you may ever buy.   Plus everyone knows Rick stands by what he sells.

I wouldn’t mess with it. I would replace it with winter around the corner

If you are mechanically included definitely open up the actuator and investigate the problem. You also mentioned that it would freeze up in winter. This one might most likely be the motor freezing due to water accumulating and freezing or your arm being in need of lubrication. If you motor is still good you can contact venture and get them to ship you just an arm which might be the cheaper route

Fellow Members, your posts are welcome here! Do not worry about posting everything perfect. Different receivers and LNB's will give you different Frequencies and Symbol Rates. Some set top boxes, PCI cards and USB receivers, Do Not Require all of the same information that others may need. It is not Required to post everything that others may need to tune in a feed. It is just most important to share the find. We can always adjust the Frequency and Symbol Rates and try the various Modulations and FEC's on our own receivers until we get a lock and then give a polite reply with what works for your receiver, as that information might help others as well. We all appreciate the efforts and energy of the Posters!
