How to gain extra signal with a motorised dish.

[PLWNTR]

Having been out in garden re-alligning my 1.1 mtr dish I found that I gained an extra 5%-8% just by turning the lnb about a centimetre to the right standing in front of the dish.This increased east sat signals and also no loss in the west sats.
As a result of this I am now pulling in some of the lower transponders with no problem.
eg NRK @ 4.8 east was 53-55 signal strength now it is 61%.
I am in north east of England and thought this might be helpfull.
Please don,t try messing with your system if you are not experienced,you could cause signal loss.
I fit all my 3 dishes including the motorised one so its no problem if I screw my own up,you might not be so lucky.

yes that is called setting the skew, when setting your dish you should always have a tweak of the lnb to find its peak setting i do this by lining up to 1 west then set motor to 39 east and have another tweak then the same on 30 west, i find this the best way for me

Motorised system, 1w (if thats your ref sat) lnb should be vertical.
The motor does the skewing.

You tried tweaking it and locking the positions via the box, It improves stuff !

everybody has there own methods i find my way the easiest and the quickest, i have fitted hundreds of motorised systems over the years and have tried different methods and takes me about an hour from start to finish, that is before i have tweak with the box motor settings...i know the the lnb is to be vertical on 1 west but to find if it is plumb you give it a tweak whilst checking your meter then you know its vertical everythng else should fall into place as long as your mount is lumb: set longitude and latitude on usals...bobs your uncle

Thanks richard

not true m8!! diseq motors are very inacurate at skewing,,for example put your dish on 16e and move the lnb a tad and i guarantee you will get improvement!! polar mounts very accurate/diseq not!

i agree some people just put the lnb on the dish and take for granted that the motor will do the rest...BJ1

i guess it depends on your referance sat and were your based but were i am i set the lnb to horizontal and then tilt it to the right(from behind the dish) very slightly (0.1 according to satsig) but having said that it is always best to try and peak your signal by ajusting the skew and also ajusting the lnb nearer or further away to get the focal point sweet spot. in the olden days recievers had the ability to skew the poloriser properly by using mecanical or magnetic means.. thats one thing that always pissed me off about digital recievers is that there are no provision for skew control and 36v motor control also. regards mdt

thats the way to do it

Having just set up a 1.6m dish I was wondering about the skew setting. I have a polar mount and center focus dish. I set it up on 28.2e and turned the LNB till I maxed out the signal strength and quality assuming that it would be correct for all the other sats but now I am thinking I will set it up on 0.8w?

So what should be done in what order?

another thought, the elevation on 28.2e is set to max the signal at about 22degrees but the listed elevations for other sats vary on any of the sat direction finding sites so does the polar mount take care of this? Is it true to say that if max signal is obtained on one sat (28.2) all the others will be correct if the polar mount is trully vertical and tracking correct?

although you can set a motorised dish to any sat you want [email protected]/5e is a very strong satellite so you could have a maximum quality reading and your dish could still be slightly out on other birds as there is room for error, id suggest try 1west and use the weaker txp,s to fine tune and you could also use amos@4w to peak your signal also. as long as your pole is 100% plumb and your elevation/declenation angles are correct your dish should track the arc properly. regards mdt
