Why don't they make one of these?

I have yet to replace my old analog receiver.

I still have it because of one reason....polarity!

I can flip a channel and it will flip my polarity from H to V and vice versa. It also has the ability to adjust the skew for the highest signal.

They have not produced (or that I ever remember seeing) a device that will take the 13 and 18 volt change from the and flip the polorator, and adjust it for the best signal.

A voltage switched lnbf works ok, but it has a drifty l.o. and makes it hard to lock some low s/r transponders. A chapral bullseye is ok, but costs about $400.

They made a pansat receiver that did that, but I have no use for it and it doesn't do HD or dvb-s2.

Why have they yet to have made such a product? A small little box, that you would hook the poloators wires into, and then lnb in and lnb out, and be able to flip the polorator.
 
Someone actually does, but it's a kit. Called "servo buddy"

looks like that is for servos on robots and such. Dunno if that could be used for a feedhorn servo.
 
Don't know why it wouldn't work, but if you are into the arduino someone has made a project on it for exactly this reason. It's sort of a kit, maybe he would even make one for you.

There actually is already a pretty good thread on this.

been there ...

We've discussed a servo-twister here on the forum in the last year or two.
One member even built a prototype device that detected 13/18volts and slewed the servo for ya.
edit: oops, comfrey linked to it, above. :)
And, it came out that there had been a similar commercial product 10..20 years ago.

Sadoun even discussed the possibility of adding the feature to a new model Gbox.
But with the bad economy, that fell through.

Give the Advanced Search a try.. I'm sure you can find info on the subject.

Well I guess I will hold off a few months and see if sadoun will make one. If we get enough people interested, it might spark and interest for him to make some. The device mentioned is a very good idea, but with 2 devices, there would be more insertion loss then using one gbox with polorator controls.
