The Exploded View drawing is the only indication of how the dish should be mounted. Because the dish quite a number of individual parts has been drawing this important. Once on the regular watch sketch is therefore highly recommended. The dish is good with bolts to the mounting bracket (Mount) screwed. First, the Mount together with the arm out and then the dish screwing on the Mount. All of these bolts and nuts are of a low zinc in order to prevent rust. If the dish is assembled, the LNB holder. This LNB holder is in fact a transverse bar, on the arm. On this crossbar, the LNBF `s. A breakdown degrees at the transom is an aid to the tune of the LNBF `s. Because each LNBF must be adjusted separately, this is not easy. Even for an experienced do-it-yourself will yield the necessary main breakers. The installed by a professional is always a possibility.
Because the dish with five LNB's can be used, the first large satellite dish be adjusted. Each satellite position is to receive its own LNBF and the LNBF must also be adjusted by satellite position. This adjustment means that the LNBF on a type of rail and was confirmed by the LNBF to the left or right may be sliding. In this way, all to receive satellite positions equip money. The aArchsat dish is certainly not a small dish and that is clearly the measurements to see. Measured course on the Astra 1, where the Dutch channels, but also on the Hotbird and Astra 2. There are three measurements made. It has reviewed the total proceeds of the dish is. It is also measured as the distance between the signal of the transponders and the background, the C / N value. The last measurement is a BER (Bit Error Rate) measurement, which measured how many errors are in the digital signal. On the Astra 1 satellite transponders, the Netherlands, measured at the Hotbird is chosen for the transponders of RAI and HRT. The Astra 2 finally is usually used for receipt of the BBC channels. Striking that signal strengths, rising to livst 84 dβμV. The strongest is the Astra 1 satellite, but also the Hotbird and Astra 2 very nice to see signal strengths. The distance signal noise shows that we have a good dish to do. The C / N values vary a bit but, lie neatly between 7dB and 14.4dB. If last is the digital content of the signal viewed with a so-called BER (Bit Error Rate) measurement. The Bit Error Rate measurement to all satellites well, only on the SBS transponder may not all errors are corrected. Stay here even after correcting errors eighteen hundred thousand bits per over. Measuring results is good, especially since the measurement at very cloudy weather were made. For the ArchSat multi-satellite dish special brackets are available, so receiving multiple satellite positions is not a problem for the ArchSat elliptical dish. Conclusion The Archsat elliptical dish is a difficult dish to assemble and supply systems, but does have a number of unprecedented opportunities. Receipt of up to five satellites is no trifle. Due to the difficult mounting a dish where it is not every do-it-yourself out the feet can. The dish by the professional can be placed than a solution. The reception quality is very good. That the transponder of SBS not all mistakes can be corrected does not say anything. This is more than on the satellite dish. By adding more satellites can be received hundreds of extra channels.
