Gilbertiny dishes are some of well regarded at the market
I am curious to know from owners Is that reputation really true
for example Channel master dishes are much stronger at first look
I like to ask Gilbertiny 1.5 m dish owners - Is this dish highly recommended In terms of gain and reliability
have someone measured gain of Gilbertiny 1.5 compared to standard 1.8 PFA
 
I can get satellites on my Gibby 1m which i could never get on a TD110. Its lightweight, easy to setup and gets me 7w and 4w, I thinks its a fantastic dish.
 
All I can say is that I have four of these models 1 >1.5, 2x>1.2, and a 1 m Dish and they are an excellent all rounders.
 
I had first a 1.25m which was a top notch performer for fringe sats down south, now i am using a 1.0m Gib for 0.8w and 4.8e and outperforms my old triax 1.1m by some distance

The build and overall quality is top notch as well

CM plastic dishes much stronger than any made-of-tin nowadays's dishes, therefore CM is better.

1,5m offset dish performs same as 1,5m PFA and will never perform even close to 1,8m offset or PFA.
Do you know the method how to compare performances of 2 dishes to be abbe to say: Dish A performs better than Dish B 5% better!

the question Is how good Is brand A compared to brand B
from my experience I can say that I am not satisfied from old CM 1.0 and 1.2 compared to the signal level I got from a new Triax
If you look at spec of dishes you will see that there are difference In gain figures - that difference Is exposed at real life like dish A giving say 5% - 10% more SNR at your receiver meter
there are PFA with low F/D and high F/D - latter give better gain
I would like to ask some forum members If they can say level measured from a tp with Gilbertiny 1.5 and same with PFA 1.8

Specify your query: Which LNBs? Which transponder? Which frequency and polarization?

And what was the signal level difference?

something from 28.2 E UK spot beam would be fine

question 2 - I don't remember exactly but I am sure about result
 
See, you do not remember your results. Do you think somebody else will remember his results from all his past dishes (assuming that he had 1,8 PFA and now 1,5 Gibertiny offset)? Only answer you can get that 1,8m PFA performs much better than any 1,5 offset or PFA dish, including Gibertiny.
UK beam from 28,28E in UK is very strong, so it is not good idea to test antennas.
 
Huevos had a Gibby 1.5m and now a 1.8m PFA. Unsurprisingly, the PFA walks all over the 1.5m Gibby.

They are good dishes (I have one) and good build quality.

Can't comment on its performance on Astra 28e as I can get that using a saucepan lid (quite literally)...
 
lets hope that Huevos will post levels
another question about Gibby 1.5 m - what Is distance between dish face and lnb holder

Did you get this dish without LNB support arms? If it is used than you better check if for warpage. Measure vertical and horizontal size of it's working area. Also measure depth in point where vertical and horizontal lines cross. Use special software (like Parabola 4) to find out position of focus and LNB direction towards dish.
 
I have no Gibertinis myself.

But I am led to believe that they're probably the best of the steel/alu consumer dishes, consistent praise á lá earlier in this thread shows that they're well made products.

Comparing them with SMC dishes is difficult. When new and pristine, a 100cm Gibertini with the right LNB should perform about the same as a CM100 with the right LNB. However, the the steel dishes rust, all metal dishes may bend and warp when subjected to heavy handing, and the mounts are a bit fiddly (as rightly so) as they are consumer products.

Semi-pro SMC dishes are meant for installations with consistant peformance, where the price is not the prime competitive parameter. All but one (my main CM180) of my SMC dishes are probably 20 years old, and still perform like they did when they were new. Sure, the plastic cracks when badly mishandled, and some of the the mount rust. But they really keep the same level of performance very well.

So, to choose between a metal 100 and an SMC100? I'd go for an SMC any day, especially the Channel Master, whatever the owners of the mold might be called. It just delivers. But it is more epxensive that the metal stuff, and if cost is relevant, I'd go for a metal dish, and of this the Gibbys seem to be the most highly rated.

Now, if you go to something like 180 cm or beyond, form stability is paramount, and SMC (plastic) dishes win hands down.

Golden words! I would like to see performance of any nowadays's dish after 20 years of usage :eek: , but CM will still work as new. :)
Therefore, today, for real sat-hobbyists is better to look for second-hand but good antenna, that is IMHO.
 
I cannot vouch for the quality of the Gilbertini range of dishes as I haven't had one, but I have read on many occasions that they are highly thought of. Channel Masters I do have experience of, I specifically chose them because of their durability, ruggedness and capability of receiving a signal well when set up correctly and I for one can't speak highly enough of them. Don't forget that size nearly always matters when it comes to dishes and receiving a signal! :D
 
My Gibby 150 was a "Problem child" from the start........maybe made in Italy... on a lazy Friday afternoon :-( .......

Extra attention to the 2piece alloy LNB holder and bracket might be needed...!!.....some (well mine was)..might be badly made..and make the LNB out of alignment.......

Also the left and right arms...might need slight adjustment to max out signal.........
But If your lucky...you might get a good one.....

I found..A standard 40mm LNB works fine....but for a extra bit of signal on certain 28,2 frequencies ...a Gibby feedhorn and Invacom can /might give good results........but the extra cost of Feedhorn and Invacom C120 flange LNB (80+ euro).....Its really worth trying a cheap Goobay or Opticum 40mm LNB first...........

Gibertini are thin flimsy dishes. Yes they have good gain, but look at one resonate in wind, its like a pair of arse cheeks warbling from a strong fart.

Yes totally Agree although the Triax are probably worse especially with that absolute shambles of an AZ/EL mount on the rear

what Is your opinion about gain of Gilbertini compared to CM , Triax, etc other brand

Never owned a CM 1.0 so cannot comment but the Gibertini is roughly the same as the Triax TD110 gain wise also include the Orbital 1m in there as well as it has a far superior and easier to adjust AZ/EL rear mount.

My preference would be 1. Gibby 2. Orbital 3 TD110 (if i really had to use one:-))
