@Llew & aceb how are you finding the moteck H180 on your 1.25 any problems encountered other than the mounting plate needed drilling, am looking into one of these myself instead of going the polar mount route


Thanks

Setting the declination was tricky with me, as the dedeclination adjustment where the motor is normally attached to the dish doesn't really help because I have adjustable brackets that bolt onto the plate that goes on the dish. So an inclinometer was essential to set the angles up correctly.

Thanks for the reply, I have gone ahead and ordered one from Red apple digital to stick it on my Gibby 1.25 same as yours with Single arm Hirschmann. I was thinking of going the Polar mount route but the mount looks flimsy and i like the idea of the Moteck bolting straight onto the back of the dish similar to the CM 1.2.

I shall let you know how i go on.

Thanks again.

Tweaking the Gibby at the extreme ends of the arc, I see a transponder at the western end that I can't recognise as to which satellite it's on. It'll be somewhere in the region of 58W, but which one I've no idea. Any clues guys?


It's a 32APSK ACM feed.

dont have time to reply in full digi but will do later. Llew, from memory that is 63w, think 11687h is another one. dishworld de forum has a long thread on it.

Sorry Digi, I was sat on Brighton Pier 'doing' lunch when I posted yesterday and I'm rubbish at typing on the phone lol So far I've had no complaints with the motor, it continues to work well, repeatedly hits the satellite OK and has no problems coming back up from the edges of the arc around 69° from south. Setting up was reasonably straight forward but I'd already set the dish up on a diseqc motor so I had a rough idea of the inclination setting but I was quite close anyway having set the motor using an inclinometer app on my phone. It took an afternoon to get it totally accurate but with both adjustments being threaded rods it made fine tuning easy. The only PITA was making small adjustments to the E-W of the entire thing because slackening off the bottom U bolt meant it tilted forwarded but apart from that everything was easy (after the initial problems of the poor build quality). Because the Gib has the inclination on it I ditched the extra metalwork from the Moteck, TBH it looked a pain to try and use anyway.

Look forward to seeing your post and pics of setting it up on the CM :)

It struck me the other day that the elevation control on the Moteck lends itself to being converted for inclined satellite tracking. It's not something I've dabbled with before so I've no idea what my options are. A short satellite actuator seems overkill really (apart from the strength) because it doesn't look like it needs much more than about 10mm movement each way and a six inch actuator adds a lot of unnecessary weight. If I do have to go down this route I'll drive it using 12V, it's easy to source in here and gives better control on fine tuning. So, is anything else available that's proven or do I just bite the bullet and get a 6" actuator?
It's not adding weight at least not from the point of view of the motor. Anyway when I added declination control to my Fibo the shortest actuator I could get was an 8" (76 pulses per inch). That was too long to fit so I just cut a bit off it.

BTW if you add an actuator in there it is not declination control at all, but a mixture of elevation control and skew. When you get near the horizon you would be adjusting is skew only, and not elevation. My mod adjusted declination only, and not skew, and works properly right across the arc. If I set it to 5º below, it will be 5º below on all satellites irrespective of which part of the arc the dish is pointing at, and that is not the case if you add an actuator to the back of the Moteck.

Yes, I hadn't thought about the skew, I could end up chasing my tail at the edges of the arc lol Nice job on yours too, I'll chew it over and see what I can come up with for mine. The weight issue isn't so much on the motor but the whole thing plus the extra wind loading. To get passed 62E it has to be nearly 3m above the gutter and it tends to sway quite a bit when it's really windy, guying it isn't practical apart from a temporary rope one for the worst of the gales.

Hi Guys,

Well its up took me most of the afternoon and the evening to get it up and running had to start with a new mount first and a new 76mm x 3m pole, It does appear i have come acroos the same issues as aceb and llew with the mount arms being slightly out and also the weatherproof cover leaves a lot to be desired.

I will get some photos up when i have the chance, Just very quickly to aceb and Llew have you any play in your motor stub because i have in mine a couple of mm at least dont know if this is the design or mine could be faulty.

HTH

Thanks

Not something I noticed when installing digi. I do have some pulse overcounting when coming back from the extreme ends of the arc, but I had that with my SMW setup too,. Possibly some interference pulses coming back to the Echostar positioner (I have a long cable), although it doesn't happen over the majority of the arc sweep.

Look forward to seeing some photos of your setup.

Not got that on mine either digi, there is no movement at all left or right of the dish in fact it was one thing I noticed when installing it.

Well a little update since yesterday anyway, after finally getting everything installed i now realised the Motor was faulty not in the respect it would not work but due to the fact it was missing some screws internally. This is where i have to give Ian at RAD a big pat on the back he sorted me another motor which arrived today but due to the unforseen weather in the good old North West and also a little injury to my hand i have to put off the final install for a couple of days.

The good news the new motor is intact of everything it should have and there is Zero play in it, Also it appears the the slight misalignment of the adaptor plates is pretty much gone in this one it appears that both plates from my eyes anyway match perfectly straight to one another so thats good, Aceb after the install the other day i feel i will have to do the same as you and swap the top and bottom plates over as it was a very tight fit with the plates as standard at least with the adjustable screw hole plate on the bottom i can manoeuvre it away from the modified back plate a bit.

All the same i have attached a couple of photo's from wednesday's install as this is what it will more than likely look like on the final install, although for motor cable i managed to bag some 4 core .1 from my local plumbers merchants as a quick fix but being white i would have preferable black . Although a trip to CEF is in the works to try and source a 50m drum in black.

If using the motor with the adapter plates at the top, like I have on my 1.2CM, you should really drill 2 holes, one each side, where I have indicated, in the picture below:

Moteck H180.jpg

I have now done this with mine, as indicated in another thread, and the motor works perfectly, I even have it tracking the arc from 42E to 30W. I still need to make some fine adjustments, using the bracket, to increase the signal, but unfortunately the last day of dry weather I used to disasemble the dish, remove the motor, drill the holes and put everything back again, 5 minutes before the rain returned.
Eventually I will get round to fine tuning, to increase the signal quality on the weaker satellites, when we have a bit of sunshine, so probably August. At the moment my garden is under water, the way it's been since the end of May !!!!!!!!

Hi CJ based in Manchester and i am looking to replicate what i had before on the interim setup with the Gibby on the Stab 120 which was Ku only 57° east to 45° west i could stretch further west for C band but that would have to be another project, I can also see around to 62° east if i raised the pole higher but due to exposed location i invested in the 3M x 76mm pole with the same thickness of a scaff pole around 3mm thick. It was heavy lifting that on my own and adjusting the brackets. LOL

Hi Mickha thanks for the response, Its slightly different on the Gibby/Hirschmann 1.2 due to the fact you have to drill four more holes central on the plate and as the nuts & Bolts stick out slightly i found the bottom plate caught the nuts when installing it. wish i had tried to source a secondhand CM 1.2 now would have been slightly easier but these things are sent to try us, A big thanks for Aceb and Llew to post there setup pics as it gives you an idea of whats needed to adapt this motor for the Gibby 1.2

all the best.

The picture is probably a little deceiving, where I drilled the 2 holes were in the bottom silver bracket, this then allowed me to move the adapter plate forward, at the bottom, and allowed me to fit the proper bolts, something I couldn't do previously, which is why I had to use 2 slender screws, as a very temporary solution.
Once I had drilled the holes, and fitted the correct sized bolts, the dish was more stable and tracked the arc better.
aceb's solution wouldn't work with my set up as I needed the adjuster bracket, on the top, to allow me to fine tune the motor tracking the arc.
As you have the same dish as aceb you should be able to use his option, of using the gibertini dish adjuster itself.
I'm amazed that the dish screws are so big, judging by one of aceb's photos. Can't you just cut them down a bit, if they are hitting the bracket?

Yes, it's looking good, but as Mickha says, and what I had to do, was to drill extra holes as pointed out in his picture - I couldn't get bolts through the original holes in any case.

Hi Llew,

so you actually drilled the black mounting holes larger so that the original bottom bracket plate would fit better, I just had a look at your picture on page 2 with the mounting holes on the bottom side slightly larger.

To be honest i think i will just do aceb's trick and switch the mounting plates from top to bottom saves any more drilling and me messing it up, my dish is the same as yours so i just took the AZ/EL mount completely off and bolted the plate straight onto the back of the dish using the supplied bolts which are just the right fit.
