Those Fortec antennas have not enjoyed the best of reports.
L.
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!
I am located near to Manchester, NW Engaland.
Thanks, Paul.
