battle of the motors, diseqc, h-h 36v and actuators

satelliteman

I now frequently rig one up fairly quickly when I'm testing here at base. The principle is the same; set the polar mount angle and get the dish on the arc by hand. It's just a matter of getting the actuator bolted on and adjusting for the amount of E & W movement required. There are guides to follow in the dish set up section for 36v

My advice would be, think about what you want first and don't rush it.

tried to find the dish set up for 36v no joy, any chance of directions.

also saw Jaeger / Superjack DG-100, surely with this i benefit from polar mount and actuator but can run it straight from a receiver with diseqc, bit confused to where it gets its power from or is it not 36v.

with the polar mount does it diverge from the arc as it tracks or is its limits in how far east and west it can go due to the length of the actuator arm

Trust1

There are also such things as Diseqc-actuators

Just to clarify, all common types of motorized satellite dish setup are polar mounts no matter if they are a diseqc motor, a Jaegar 1224 motor, or an actuator. They all work by the same principal it's just that in the case of a motor, the bearing surfaces of the polar mount are inside the motor body.

A polar mount driven by an actuator does not diverge from the arc if correctly set up. The problem is it does not track the arc in a linear fashion, for example, if the actuator were located on the east side of the dish you would get about 7 counts per degree at the finest point with the dish pointing somewhere towards the east but when moved to the west extreme the angles are such that you end up with only 2.5 to 3 counts per degree (which is not fine enough for difficult sats). With the Jaegar 1224 the count spacing is almost linear all the way across the arc with about 12.5 counts per degree.

The actuators and motors have hardware limits and it is imperative to set these correctly so 1) in the case of the actuator it can't go over centre and 2) in all case that the dish cannot be driven into a wall or other obstacle or do the motor some internal mischief. Once the hardware limits are set you then set software limits with a slightly broader margin so that the hardware limits are never reached. Software limits are set at the receiver or v-box.

does any one have any experience of this superjack dg 100,
just wondering if it is going to have the power drain problems some of the diseqc motors have.
also is the polar mount any good and can it be mounted to any dish or is it dish specific
cheers all

There was a thread about this the other day so try doing a search. In the end the guy rebuilt it with an external power supply.
