IDD CI24 ECONO MM Penta 1.20 Galaxy II
1.2Mtr Polar MTG yes it has been on the arc for 25 years and is now fixed on 13 East using two pairs of rusty molegrips. Unlike me they never groan but always perform.
I have been trying to use a fortec 2.4 m petalised dish for Nilesat and the MBC channels. I have been dissapointed with the results. The reception is borderline at best. The signal drops out in the afternoon and only returns early evening.
I have read reports that the fortec star only works as well as a decent 1.6m to 1.8m dish and I tend to agree. I have resurected my old 1.6m Connexions dish and the fortec only shows a marginal improvement, not what you would expect from such a diference in dish size.
I was planning to upgrade the lnb/feed to an invacom but am now thinking that the dish is really not up to the job in hand.
I have run tests with string lines etc and no matter how much i adjust the petals of the dish, I just can't seem to get it into shape. Also it seems nearly impossible to locate the feed at the focus of the dish if in fact there is in fact a proper focal point!
I am now considering trying Arabsat at 26E C-Band in order to receive the MBC 1-4 channels. These are my main interest as I have family that visit from Dubai.
I am really guessing that if the dish is really bad at Ku band it may be more forgiving on C band.
Would a 2.4m be large enough for the C Band arabsat channels and can anyone point me in the direction of some GOOD information regarding downlink budgets, Eirp's and G/T etc. I would like to be able to calculate wether something may be possible before it costs me money!
