How many isolation db for 432 mhz relay

Webthe antenna, two stations equipped in this way will have several extra dB in hand — that is, they should nearly always be able to work each other by EME. Audible self-echoes and CW communication with a twin station will require something like dB in 50 Hz bandwidth, and thus about 10 dB more transmitter power — say 700 W at the antenna. WebFor a balanced splitter, the theoretical insertion loss is defined mathematically as L dB = 10log 10 (N), where L dB is the loss in decibels, and N is the number of output ports. For example, a balanced two-way splitter has 10log 10 (2) = 3.01 dB of insertion loss between the input port and each output port, and a four-way splitter has 10log 10 (4) = 6.02 dB of …
