Hi, for those members out there that know something about so many different topics here is one dealing with Diseqc switches. I need to buy one but I need to understant a few terms on the spec's. Comparison of the switches in question. Input freq: 900-2400MHz, Isolation 25db's, passing current. 450mA(max) output return loss: 6.5db's. (first switch). Other switch. Input freq: 950-2150MHz, Isolation 27db's, no output return loss given, passing current 600mA, max. Which would you buy. Other spec's given are understandable, but where can I obtain info. on what those terms mean. Describing them here would take to long. Thanks so much.
