I just acquired an Old Triax 140 Prime Focus dish. I do not know anything about it. I am asking you guys what you think of it before I take it up 13 floors to install. I know Turok has one of those. How does it compare with my CM120 offset dish? Thank you | ||

It was used to bring in Nilesat, and, according to the installer, it was bringing in all Nilesat, rain or shine. The reason that it was removed was that it was not in possession of an "urbanism permission" It is made of aluminium and the dish itself without the mount does not exceed 3 Kilos. I paid 50 Euros for the whole lot including a heavy 10 bolt wall base with a 70mm mast. | ||

My System: 3x Dreamboxes 13°, 19.2°, 23.5° & 28.5° East 7°, 8° West 2.4m Aerial Oy for Nilesat Subs: Canal+/Sat France, Premiere/arena, TV Vlaanderen | I live near Brussels and I have a 2.4m PFA for Nilesat. Frankly, it is not serious to pretend to get all Nilesat, rain or shine, with a PFA 1.4m. The horizontal transponders will not work (Showtime). | ||

The matter is still to be verified. I removed the dish for the time being while I gather the necessary elements to make it work at its best. I am far from having all. | |||

I decided to post this anyway. Having given the task of verticals on Nilesat to a Triax110 with an Invacom, I already receive horizontal transponders on Nilesat with a good percentage reserve on my Channelmaster CM120 plus CM911-6060-10 feedhorn and a Norsat 0.6db. My assessment of the situation is not yet final as I have not had very nasty weather since the beginning of this experiment. My feedhorn, however, has a circular throat and I had to use a transition to WR75. This certainly increases input noise. I am waiting for a feedhorn with a rectangular throat (WR75 output) this would dispense me from using the transition. I expect, this way, an improvement of the input noise characteristic. The bigger area of the Triax140 gives the potential of increasing reception by 1.34db over my Channelmaster. Hence my search for a WR75 PF feedhorn designed for the standard band in order to improve on the same favourable combination required for the Channelmaster. All this because I do not want a 180cm dish on the 13th floor of the building. | ||
