Hi,

Tried to have a look but couldn't find a post related.

I am VERY new and inexperienced but I have managed to setup a 80cm "normal" round plain dish with a "low-noise" fortec LNB twin feed and a HH90.

It is kind of working, apart for the HH90 having fittings made for 5m diamater poles (...) and the "backlash" (I think ..) as the dish vertically is very unstable .. and I live on the west coast of scotland which means that the mounting has to be PERFECT or you're back on the roof every 2 days.

ANYHOW .. I am now thinking of adding to that an actuator to control elevation. I find many actuators around however I have not understood the following:
- What's the difference between lengths of actuators ? (How much they can elevate etc. ?)
- Can I know from the length if it supports a specific dish diameter ? How to tell if it supports my dish ?


The two feeds from that LNB + a feed from a second fixed dish are used with a cheap FTA digital receiver and a SS2.

Is there some sw or setup out there to automate blind scan via a SS2 which also moves the dish to different positions and scans each transpoder ?

Tnx !

Eh??

I assume you mean 50mm not 5mm. What is wrong with a 50mm diameter pole? For a little dish with a nice strong scaffold, it should be sufficient.

The HH-90 is a problem though, too much backlash and play. The Motecks and Technomate motors are far better in this respect.

If you have it set up properly and not needing to do anything out of the ordinary with your system, an actuator to adjust the elevation is totally unecessary.

That type of adjustment is applied to the more expensive, maybe larger, normally polar mounted motorised systems. It can be used for inclined orbit satellites and the like, not for correcting a badly setup H-H motor

5m was intended as 5 meters .. and was just a figure of speech meaning that it's HUGE and for small poles it's troublesome to fix properly.

About the actuator .. I've put too much stuff in the same post ... it wasn't intended to fix that problem but to have more flexibility in pointing to "any" satellite visible to me.

Is there any guide around on use of actuators for average size disks ?

Size required depends on the length of movement needed.

That's so true in many walks of life.
