Moteck motors got really bad quality!

[rolfw]

I have measured the C/N going thru the Moteck, this is really crap, not that it got bad clamps, it even have huge losses, i lost about 0.8dB C/N going thru the Moteck, making BBC and the others on Astra 2D to start pixelize a bit on my dish.

What is this? this is really bad!!

And are other DiseqC motors any better?

 

[deepbluesky]

Likvid very interesting point !!

For me this is the most important thing on a motorised system: not too lose unnecessary signal.

Better choose an actuator if you have space although another cable is needed for it.

How would i know? you seem to know everything right?

 

[Likvid]

Too late for that now.......

I guess i need to bypass the motor and run two cables to the dish and terminate the other connector on the motor.

Another thing worth pointing out is that this motor isn't much more silent than the 36V motors from Jaeger.

People said Diseqc motors are so silent compared to 36V, yeah right!

I guess a SMR1224 would have been better now when you know all the answers.

Likvid very interesting point !!

No, not at all Likvid, but if you are going to apparently enter into a crusade against a motor, then you need to give comparisons with performance on the others.

Of course there is going to be an insertion overhead if you run the signal through a motor, switch, or any other type of connection, but the way you have presented it is that it only happens with the Moteck.

ive got both motek and the stab motor.the stab is very reliable.the motek i have is a good one,but i know people that have had problems with theirs.Manhattan is a pretty good motor and reasonably priced.quite reliable!! no probs,so far :-)

It's certainly been reported, with noise figures to back it up, that the Moteck is considerably quieter than the STAB.

It's blo-Oo-Ody obvious why when you check the internals

I also get minimal signal loss at the receiver when inserting the Moteck (just using the internal sig. meter on both Dreambox and SS2).

About how much are we talking here ? In dB or pehraps % whatever your receiver uses. I wonder if it is really worth talking about, but would be interesting to know what it looks like in real life.

Here is the picture of true Chinese quality and the sheered off nut.

hey, same thing has happend to me. first bolt went in the first day when i was trying to setup. Then adjusting the other day, 2 more bolts have gone!!! it is still on the wall and tight, but i need to take it off because i need to adjust the support. its not 100% vertical. So you were lucky and found some old Ubolts lying around? what do you suggest I do? Rolf suggested just using 4 long threaded pieces with bolts on both ends? think this would work? Also my support bracket is crap, i think, shakes around a bit and is VERY hard to get vertical. Have you had experience with a motor on a support like this?

 

[REBEL]

Likvid,

Here's some comparisons for you, got a stab hh120 is a great motor,

I would change that support bracket if I were you,doesn't look strong or stable enough to support a dish and motor!

What is that lnb you are using,is it a Humax?

You can buy new original brackets from here:

I wouldn't hang a tea towel on that bracket personally, which Meccano kit did it come from???

 

[rolfw]

Those brackets are fine for a single dish, perhaps up to 80cm (sheltered), but they are far too difficult to get perfectly vertical for motor usage, still favour the T&Ks myself.

The U Bolt replacement is not too difficult, the easiest solution I found was four coach bolts with half of the circular head filed away, this locks them against the bracket body. Any small engineering comany will be able to make a replacement for the broken U Bolt with threaded rod.

this thread is going off topic now thanks to me, but yes it is a humax. and i realise now that bracket is not strong enough. I am so fuming with my so called "expert" italian cousin. i had never setup a dish before in my life and he said he would take care of it all. I like to research stuff a little better myself but he took control and bought crap, like that bracket! couldnt set it up for two days. then he just gave up, he had NO IDEA. I knew that the support had to be vertical at least but hes like, ahhh, nema problema.. then lining it up he just thought there was some magical search function that lined it all up, even though it wasnt pointing south. ive just spent the best part of another whole day getting the thing vertical its almost 100% now. If this fails ill go buy a better bracket tomorrow, actually i wish i read this post earlier! iwoulndt have wasted my time. where were you guys before??? anyway, ive learnt a lot and the bracket didnt cost much. the lnb is .03. the shop only had them or invacoms. invacoms were almost triple the price. they had no titaniums. are humax lnbs crap? i might as well just go and buy the invacom now if it is, while im still setting it all up. thanks for the advice and sorry to go off topic here.

Your Humax lnb isn't crap,it isn't manufactured by Humax but they would never put their name on any crap.

Would be nice if you could compare it with some other 0.3 lnb sometime when you have the opportunity!

By the way I'm using the same dish as you for the moment and you will have a very good result when you have changed the bracket!

 

[Likvid]

I have done some research and have found out that the one to buy is the FTE Dimo 120, it is the Moteck but with a larger diameter on the pole, 57mm, which makes it more sturdy and suits heavier dishes.

 

[steffan_st]

A maximum weight of 27 kg:s isn't bad.

 

[Likvid]

With DiSEqC 1.2 motor DiMo 120, it is posible to install easily and fast a polar mount system with a 1,2m antenna. For its correct installation, it is indispensable that the receiver dispose of the DiSEqC 1.2 protocol. The engine is made of aluminium and it only need a coaxial cable to be connected. The satellite signals sent from the LNC are transmitted by this very cable. The polar mount is integrated in the motor so as complex adjustments are not needed. In total, DiMo 120 can save 60 satellite positions and with the manual settlement system, it is easier to install it.

Code 6000508 Maximum size of the dish Offset 120 Antenna maximum weight 27 Kg Compatible DiSEqC 1,2, Goto X Memory Max. 60 positions Functions Goto X, Goto O Mechanical limit 20º-70º East - West Rotation angle 140º, 70º East - 70º West Weight 3,1 Kg Fixing tube diameter 30 - 70mm Antenna fixing tube diameter 55mm Rotation accuracy < 0,1º Rotation speed 2,5º/sec. At 18V horizontal, 1,9º/sec. Motor maximum consumption 7 W max. LNC supply 350mA max. Connectors F-type Packing quantity 1

Oh dear.... just bought a Moteck myself and was planning to install it today then I had a look at this forum and ! 1) I'm not sure is such a bargain after all but above all 2) I'm not sure I can install it with my current config ! (see links below...)
