[QUOTE="nadal liu, post: 1030587, member: 401837"] Thanks so much for your reply. Regarding your question: "Your MSs give up to 16 volt, but your LNB needs 18 Volts?" My stb sends 15v and the mono-block Japanese LNB that I modified also needs 15v. It is the regular dual LNB that needs 18v which I use with a modified EMP centauri MS with external power supply. Like I said, it is been modified so that it switches between h and v at 11v/15v, while sends 13v/18v to the LNB. "More often I see the use of cascaded multiswitches. So the splitting is done inside of the MSs. Have you thought about such a solution too? Or is that hardly possible in your case?" I never heard about the term "cascaded multiswitches" I will study a little more on this. Maybe when I have time and resources, such as additional dishes besides the ones in production, I will experiment more about this. For now, I can use zinwell 6x8 and two modified monoblock, and 2 22k switches to provide service to up to 8 stbs. Just for the information, for a multi-stb system, Japanese companies have provided expensive solutions, which is different from a MS solution. The whole system costs JPY 200,000 or more, not include stbs. For this reason, I have been searching for a less costly way to achieve a multi-stb system for Japanese satellite. It is lucky that I was able to contact EMP and they are willing to modify the ms for me. As you know, a 4x16 emp ms is in the range of 100-200 euros only. Later, I found that some Japanese uses two dual-output monoblock LNBs, which was originally intended for users who want to have up to 2 stbs in their household. They use it and a zinwell 6x8 ms that doesn't need external power, but passes power from stb to lnb. And zinwell ms switches correctly on 11v/15v, too. In Japan, they only need 45cm dish for their satellite 124e, and 128e. The mono-block LNB fits and works perfectly on a 45cm in Japan. Therefore, they don't need to modify the monoblock like I do. In Taiwan, where I live, I need 90cm to 120cm dish to receive the footage. The monoblock doesn't work on a 120 or 90cm. Therefore, I need to modify it. I have friend in Taiwan, who modified the Japanese monoblock so it works on a 120cm prime focus dish, like in the attachments. Again, thanks for the info you provided. [/QUOTE]
