Review on Optimize Satellite Reception with DIRECTV ASL-1 SWM Alignment Signal Locator Tool by Ronnie Segobiano

I have used this with a Birdog USB Plus. Works as expected. A few tips for those who don't know about this switch, the wiring is as follows: ODU connector: It should be connected to the LNB of the satellite dish. 18VDC Out: Not used DC Power In: This should go to your DirecTV 21V Power Inserter119WL Skew & 101WL Alignment: They connect individually to your signal meter. Connect to port 119 when tuning satellite 119, then connect to port 101 when tuning satellite 101.
