[QUOTE="2old4this, post: 5873, member: 174998"] DiSEqC v1.0 can indeed only switch between LNBs, not drive a motor. For that you need DiSEqC v1.2 (or higher) and even then you need a special kind of motor which can understand the incoming DiSEqC commands. Some receivers are able to work with both, and indeed many receivers originally marketed with only DiSEqC v1.0 capability have since had software upgrades made available for them which give them the v1.2 capability. You should check whether that applies to your own receiver. With regard to "actuators" - you should find it defined in any english-language dictionary. In the satellite world this and the term "motors" are synonymous . Mericans usually refer to "actuators" while Yerpeans usually refer to "motors". They are simply the devices that drive the dish. A mount is what attaches the dish to the mast or wall or whatever. A Polar Mount is intended for use in combination with a motor/actuator. It is a mount angled in such a way that when the attached dish is driven, it traces an arc which follows the Clarke belt of satellites. An alt-azimuth mount by contrast would not follow an arc but would offer two linear movements: up/down or left-right. So lining up each satellite on the arc would become quite tricky. "H-H" I have already defined (have you forgotten already? ;-) See http://www.satellites.co.uk/scripts/webforum/DCForumID3/50.html# I would repeat the advice I gave in that post: namely to consult other sources for these basic definitions. I just tried typing in "what is an actuator?" in Alta Vista, for example, and it immediately gave me a site with a good definition. Or consult the glossaries in the many satellite publications around (the UK magazine What Satellite has one every month). Or see if your local library has a book on satellite technologies. I'm sure you'd find that these basic concepts fell into place more easily and quickly that way. 2old [/QUOTE]
