gibertini OP125L install issues

[speedy_04]

finally decided to retire the triax 110 dish and upgraded to the gibertini op125l dish. after faffing about with the mount bracket to fit on to a technomate tm2600 h2h DiSEqC motor, i have an issue. followed the steps and set the dish at 1 west and getting 100% signal and getting good signals to the west up to 15w. but when i move beyond 7e all the signals have dropped around 40% compaired to the triax dish. once you go beyond 19e there is no signal. any help would be great as i am stumped

There are images that help explain the problems, when tracking the satellite arc, and how to fix them.

you wont be tracking the arc close enough you could be moving in to tight of an arc or to flat. Did you move the motor at all or just swap the dish only?

did you get it off a well known orkshun site recently - from Wokingham?

[speedy_04]

did you get it off a well known orkshun site recently - from Wokingham?

no it come from a well known and highly rated supplier to the satellite community. i have adjusted the mounting pole as it was not straight. made adjustments to both the motor and dish and still have the same issues where i can now get from 1w to 15w and nothing beyond. and now have no sats to the east.there is plenty of Clearance so can not figure out why there is no signal

[Mickha]

Can you post some of the channels, you are getting, and the signal quality readings, along with the satellite.
Can't you even get 4.8E? Channel 5 Ukraine 11747 V 30000 DVB-S2 8PSK 3/4

[funtime26]

hxxps://www.dishpointer.com might be of help if you have any potential obstructions. This told me my neighbours chimney was blocking 30W. Useful as gives the max height any obstacle can be before blocking line of sight on any given satellite from your location.

I tried that dish a few years ago and gave up, went back to the triax 110cm. That dish would dent if you brushed past it and is it completely dent free on the face? The mount bracket is the secret and its not easy. And does it have that fine tuning screw/bolt?

Was dish new?

The triax is hard to beat.

[speedy_04]

it was brand new fully boxed and dent free. it has the fine tuning bolt and after discussions with the supplier i fixed the mounting bracket so it sits completely flush. once the weather clears i will redo the dish and motor settings. think i may have set something incorrect

[dog-man]

Is your dish able to turn fully?
Reason I ask is that sometimes with this dish and a H - H motor, you need one or two spacers to push the dish out away from the stub it sits on.

[Mickha]

I have read of some problems, with one particular make of dish, as they have been sending the wrong length feed arm.
I can't remember which dish it was, but apparently the feed arms have been mixed, so some that were made for a smaller dish has ended up with the larger dishes.
Check the manufacturers website, and the dish dimensions, just in case.

i would losen the motor bolts, and give it a few up and downs in case its stressed to one side...then tighten up again.

[speedy_04]

i have now looked at it from all angles and now know the issue. as i have the technomate tm 2600 diseqc motor, this is the cause of the issue. the motor hits the mounting bracket which stops the correct tilt but was also causing the tilt to be pushed back. so the solution was to change the motor to a stab 120 h-h. it should be here ina few days. this should finally fix the issue as this will allow the correct tilt angle to be obtained on the dish.

That's why I asked if the dish can fully turn.
You need a spacer or two to push everything out further from the H - H mount.

[speedy_04]

i got the new motor, tested and working but now waiting on spacers to stop the motor hitting the bracket. found this out on a mock fitup before installation. hopefully this finally fixes the issue but will be a few days before i can do anything due to the weather lol

Be great to have a few pictures when you done. I myself been thinking about a Gibi OP125L on a TM2600! :respect-061:

me too, but have a 1m Triax TD110 (retired), and a 1m Gibertini at the moment (active).

looks an OP125L is not meant for a diseq motor...?

[malsat]

I have mine on a diseq motor

still amazed your not losing signal with the camo covering

its plastic so no different to paint

[speedy_04]

as we got great weather today, got around to fixing the dish. glad to say all is now working from 50E to 30W. there was some modifications that had to be made, i have posed pics of the mods and final install. but having to fully realign all brackets and pole helped fix issues. i am very impressed with the performance of the dish and was well worth the investment. thanks everyone for the help.

But you will get some loss of signal if it gets wet or frost covered.

[ManikM]

me too (in relation to covering the dish with a net, and not losing signal)

[ManikM]

dont suppose youve got a signal level comparison, between old and new gibby have u.

i cant make out what you've done.

if i was to get one, what else is needed for the bracket \ on a TM2600 motor ? thanks

[speedy_04]

i had to bolt an additional plate to the polur mounting bracket. the dish comes supplied with 2 box section brackets which i have added pics to show,which i have placed one on top of the other. i dont have pics but can tell you the differences. 3W on triax was 38% on gibby 60%
badr 26E was only getting 11996 H 27500 40% on triax but on gibby 72%. still no luck on 4W and do not get 7W in my location but do get 21E about 60% on strongest transponder plus get 33E and 36E and 46E now where as with triax i could not pick them up previously

Real help all this info and great pictures above speedy_04. Now know what the issue is and what's required. As a result just ordered my Gibertini OP125L for delivery end of month. Thanks all been a real help! :respect-048:

on my 1m Gibby - i get 26e 11996H 27500 - AT 74% (12.0 DB) - i also get 4w and 7w, and get 98% at 45e...I think you should be getting more from your dish mate. where in the UK are u? im SE london.

(having said that - every STB has there own "version" of signal strength - decibels is probably the only way to compare apples to apples)

furhermore, and just to re-iterate my point, there is a feed right now on 7e, my ZGEMMA H7S reports signal at 47% - my OCTAGON SF8008 reports signal at 58% - the actual value is 9.50 DB on both STB's - both coming off the same DUAL LNB

central scotland. i can get 4w on certain days - weather permitting. i have checked the 7w footprint and from where i stay i miss 7w altogether and just get 8w. i have tried to get 7w with no luck but i get what i can in the area which is 50e to 34w

[ManikM]

have u tried tweaking your usals since setup.

even though i set my dish and motor up using the correct usals - i always find this isn't the end of it.

after you fine tune on 1w \ 3w or 7e - goto positioner setup - and then fine tune east and west, if your signal goes up, then exit that, and edit USALs by either going up .1 or .2 - then go from another sat and back, and see if signal is better, if not, then try going down .3 or .4 and repeat until you are pulling in the strongest possible signal! (its very satisfying doing this) i spend ages doing it, drives my mrs metal! :)

[speedy_04]

i have no idea how to use usals so its all been done with a spanner and a sat meter. have double checked all the footprints and 7w is just not possible for me even with the gibby dish

what receiver are you using?

[ManikM]

usals is something you do on the receiver, make sure your latittude and longtitude is correct (use dish pointer dot com ) then adjust accordingly by tweaking the values either way

what i was going to say

[echelon]

interesting to say the least, I still use a TRIAX TD110 dish and have recently had to change from the d@rkmotor or one with a different name on it, but basically the same motor , which point downwards

in the past I have had a STAB motor that pointed upwards and a TM2600 which pointed downwards

it looks like you changed from the downwards pointing TM to the upwards pointing STAB from the pictures


that top bracket reminds me of the metal brackets I bought to screw my fence panels together across the concrete uprights , so I assume you have added it for added strength due to the weight ?

and adding the angle brackets is just to "pad out" the actual mounting bracket to push the dish away from the mounting spigot ?
or is it there to sit on top of the mounting spigot to hold the weight ?

I assume you didnt need extra angle brackets for the scaffold pole mount itself , just to keep the dish away from the motor

its definitely an interesting yet back to basics project, just some extra metalwork and nuts , bolts and washers etc

well done

the two mounting brackets are used to push the dish out enough from the motor. without that set up i would have had to purchase the kit that you can use a super jack motor (see attached) but that would have added a lot more weight. think it was around another 5+ kg and also extra wiring on top of that so going to a stab motor was the best option.
