Up for sale is a brand new DirecTV approved 4X4 multi-switch. The model is ZINWELL SAM-4402-3A.
4 X 4 Multi-Switch
(2 SATELLITES TO 4 RECEIVERS)
For use with FTA RECEIVER AND DirecTV
Zinwell Multi-switch Model SAM4402-3A is designed to distribute 2 polarizations (usually RHCP and LHCP or V/H) from 2 satellites to up to 4 IRDs. Polarization selection is by 13V/18V LNB voltage switching. Satellite selection is by a 22KHz tone on the LNB voltage which is present when the second satellite is required.
No power supply is required as the IRD's voltage is passed to the desired LNB. Only the desired LNB is powered (switched by 0KHz or 22KHz), the IRD's power supply is not overloaded.
