[QUOTE="Tururu, post: 933413, member: 227656"] The section of the living (center wire), 1'25mm is good, but not nearly long to have voltage drop, or 14 meters (45 feet), usually these problems are noticed above 40~50 meters and smaller diameters or equal to 1 mm, with lengths as short as I say, not normally have to notice. The lost signal is 24dB/100m to 2150MHz, very good. With this cable and 14 meters, you lose 3'36dB (connectors apart).33dB Weak cable, you lose 4'62dB (connectors apart). The voltage drop for 14Voltios and 0'5Amps, according diameter of core wire (live), without taking into consideration adapters: Diameter 1'25mm = 0'20 Volts Diameter 1'00mm = 0'25 Volts Diameter 0'80mm = 0'32 Volts Securities difficult to measure if you have a digital meter RMS (real value). I remember years ago an update of the official software in 2005 tuner FTE IRD390, earn 25% extra signal and nearly 5% more quality, measuring Like other tuner MVision FCIS7000E+ I had then.[IMG]http://www.imagenonline.com/img_a4540.gif[/IMG] Having seen, the values in dB signal level are more generic between different receivers, I use Dreambox800S-HD and VU + DUO2 usually also I have DB800se, DB7020Si, DB500S, DB600S (sold). -------------- La seccion del vivo (hilo central), es buena 1'25mm, pero no tiene casi longitud para tener caida de tension, ni 14 metros (45 pies), normalmente estos problemas se notan por encima de 40~50 metros y con diametros menor o igual a 1mm, con longitudes tan cortas, como digo, no se tiene que notar normalmente. Las perdidas de señal son 24dB/100metros a 2150Mhz, muy bueno. Con este cable y 14 metros, pierdes 3'36dB (conectores aparte). Con cable malo de 33dB, pierdes 4'62dB (conectores aparte). La caida de tension para 14Voltios y 0'5 Amperios, aproximadamente son segun diametro del hilo central (vivo), sin tener en cuanta adaptadores: Diametro 1'25mm=0'20 Voltios Diametro 1'00mm=0'25 Voltios Diametro 0'80mm=0'32 Voltios Valores dificiles de medir si no tienes un medidor digital RMS (valor real). Recuerdo hace años una actualizacion del software oficial en 2005 del sintonizador FTE IRD390, gane 25% de señal extra y casi 5% mas de calidad, midiendo igual que otro sintonizador Mvision FCIS7000E+ que tenia entonces.[IMG]http://www.imagenonline.com/img_a4540.gif[/IMG] Visto lo visto, los valores en dB del nivel de señal son mas genericos entre distintos receptores, utilizo Dreambox800S-HD y VU+DUO2 normalmente, tambien tengo DB800se, DB7020Si, DB500S, DB600S (vendida). Approximate data, rule 3 for losses (2150Mhz) and loss calculation DC level for copper wire diameter of such diameter and such consumption (0'5amp. = Motor + LNB.). ------------------- Datos aproximados, regla de 3 para las perdidas (2150Mhz) y calculo de perdidas de tension continua para el diametro de cable de cobre de tal diametro y tal consumo (0'5amp.=motor+LNB.). PS: Errors as always are welcome/Se admiten errores como siempre.[IMG]http://www.imagenonline.com/img_a5995.gif[/IMG] [/QUOTE]
