| | SW-21D | SW-22 | SW-1418 | OMS-34 | OMS-44L | |
The SW - 21D is a RF signal selection
switch which use in satellite receiving system. It can accept two
signal from LNB of satellite dish then selecting the other one to
pass via power OFF / ON of satellite receiver.
If the signal of set - 1 is passed to satellite
receiver and the signal of set - 2 is OFF, when power OFF then power ON
the signal of set - 2 is passed and the signal of set - 1 is OFF.
** (The time from power OFF to power ON not more than 5 second.)
** (Best choice If your satellite receiver does not have 14V / 18V or 0KHz / 22KHz function.)
