Gibertini 150 or CM120!?

satphreak · 09-10-2008

I have had a good reliable system with my motorized Triax TDA 110 for some time now - but as I'm about to move I will change to a fixed system instead. I will install one dish for 1W, 5E, 13E and 19E - and one for 28.2.

Now - with the Triax TDA 110 I have been receiving the horizontal channels on Astra 2D (BBC1-4 etc) apart from in heavy rain - and now want to get a more stable signal here. I'm therefore torn between getting a Channel Master 120 or a Gibertini 150! The Channel Master 120 should give me the horizontal channels 24/7 - and most vertical channels 18/7. The Gibertini would give me all channels 24/7 - in any weather.

Now - I need to have this on a roof - is it safe to put a 155x165 aluminium dish on a roof - will it be OK in heavy winds and in a few years time ? How heavy is this dish - can I get it up there ?

The Channel Master I know will perform and last - but as these will cost the same - it's worth considering...

Either will be used with a CM feedhorn and a quad Invacom C-120 (QDF-031).

The Gibertini 1.5m dish is quite light not heavy at all, should be safe enough to roof mount.

Sounds great. Now I just need to decide - as it aesthetically will be better with the CM120 dish... Hmm, decisions, decisions

As far as build quality goes, there is absolutely no contest...Gibertini is a cheaply made, mass produced, low precision product, while Channel Master is made for professional use, and believe me it shows. Just compare the feedhorns or the polar mounts and you'll see they are in a completely different league. I think Gibertini are overrated. There is no doubt that the 1.50 Gib will have a higher gain and will get you those horizontals more reliably, but for how long? The CM will be up there for 10-20 years once you've set it up right. You probably have highly variable temperatures and high winds up there? There is no way the Gib will stand up to that like the CM. And how easy will it be to set up the inaccurate Gib polar mount compared to the solid, well engineered and finely adjustable Channel master? Just my opinion

I totally hear you

And yes - tempuratures varies a lot over the year - and yes, winds can be pretty bad at times - although we are not in the windiest area of Sweden.

As mentioned - I will be using a CM feedhorn - as I've been told it's the best out there - for the Gibertini or the CM dish! And to be honest - I am seriously leaning towards the CM120 dish - as it's better quality, quite a bit smaller - and will do the job almost as well. The horizontals shouldn't be any problem for either dish - my Triax TDA 110 (110 x 100) has pulled them in in most weather conditions - it's the verticals where it would make the biggest difference. With the Gibertini 150 I would be sure to get BBCHD for instance 24/7 - with the CM120 - probably not at all or only in good weather.

However - somehow I believe I can probably live with that...

The dish itself will be fixed on Astra 2 (28.2) - so I wouldn't need a polar mount for it - but certainly - as build quality goes - CM is obviously second to none...

Hi sorry to butt in, but I live in Karlskrona towards the South of Sweden, and have just brought over my Sky over from the UK, and trying to pick up the Astra 2D. I have a 80cm dish which I got for free to try, but that didn't work. I could pick up regular Sky channels, but not BBC, ITV channels. I'm a bit new to this, but it looks like a need a bigger dish, and better LNB. Can anybody please inform me if a Gibertini OP 125 with a MTI AP8 XT2 LNB would be sufficient to pick up both Sky and BBC, ITV channels. Any help would be greatly appeciated.

My location is some 50 km:s north from you and I use a 100 cm Gibertini,a rather sensitive Humax receiver and a good LNB.I lose the picture in drizzle late in the evening when signal gets weaker.In clear weather it's just fine 24/7.

SIgnal is a bit stronger here than in Rödeby so don't be too sure an OP 125 would do the job for you.Remember that practically the difference between a 100 and 120 dish isn't too big.Best for you would of course be if you could borrow a dish for testing

Thanks for your help. I've now purchased the set mentioned, but am not due back to Sweden until the end of the month. I'll let you know how I get on.

Size always matters.

Take gibertini.

i'd go for Channel Master

Quality over quantity

***BombedOne*** · 06-07-2009

You know, I've compared VSAT channel master 1.2m dish versus cheap 1.2m noname dish. Signal strength difference was neglible. Only noticeable difference, since dish and arm are much more solid, almost no impact of heavy wind. That's all.

You can buy cheap but big dish, and successfully reinforce it. But you can't "grow" 1.2m dish to 1.5m one

yes, quality of signal will be better and stronger with the Gibertini 150 than with the Channel Master / Andrew 120.

You guys confuse dish size (= stronger signal) and dish built quality.

I have both the Channel Master 120 and Gibertini 150. I can tell you that the Gibertini will give a much stronger signal. And regarding built quality, the Gibertini 150 is very well made and very strong. It is true however that the smaller Gibertini 80 - 100 are cheaply made and seem very fimzy.

Also, Channel Master / Andrew don't make a 150cm; so the competition to the Gibertini 150 is the Laminas 150 from Poland. The Laminas is made from reinforced expoxy glass and is very lightweight. It looks like an excellent dish and can be a great choice for the roof (because of its lightweight).

So, for me, I would definitely go for a 150. Either Gibertini or Laminas.

Nothing can substitute for size in sat dishes / reception.

Except dish type. For example, due to higher illumination efficiency, Cassergrain dish of same size vs ofset or primefocus dish, will have higher strength of signal. Roughly 1.2m cassergrain = 1.5m primefocus.

I highly doubt what you write.

Please give spec sheet of a 120cm Cassegrain dish in order to compare with spec sheet of 150cm Offset.

Furthermore, can you give address of shop where the Swedish fellow can buy a 120cm Cassegrain dish?
