Can you explain the purpose of a diode steered splitter over a regular splitter... I am just trying to understand the application of this specific type of hardware.
A "normal" splitter is only for HF-signal and is DC-blocked.
A power-pass splitter has DC-through (= power pass) functionality: an extra diode inserted over one port, or over both ports. (Two types available!)
It is used to prevent that the LNB-power of one receiver reaches the other receiver (to avoid possible damage).
With a 2-port power pass, if both receivers are on, there could be some interference there.
Even better therefore is a sat priority switch, such as this: hxxp://wxw.pulsat.com/products/Digiality-Smart-Priority-Switch.html
or this hxxp://wxw.amazon.co.uk/electronics/dp/B0051C2BWC
or even cheaper: hxxp://wxw.voelkner.de/products/358896/SAT-Priority-switch-Vorrang-Schalter-verteilt-schaltet-1-LNB-auf-2-SAT-Receiver.html
(replace tt for xx in hxxp and www for wxw, I couldnt get this posted otherwise......)
These have a 'master' port, and a 'slave' port.
As I understand it, the HF-signal should also reach the slave-port, even if the master has control. In this sense it is more a splitter than a switch: the switching is only for which receiver has (voltage)control.
