22 k switch

[10rSatMan]

Just picked up a steren 201-740 22k switch. I have used 22k before but this one has the input labeled 14v and 18v.  Looks like a polarity switch but I wanted to switch between c and Ku. I have a motorized Ku and a c band controlled with a vbox. I was thinking the 22k would cause less  problems. Thanks

That is weird, usually a 0/22 switch has LNB A 0Hz, LNB B 22Khz. I wonder if the switch you have is not for 0/22 and maybe it is for Directv or something specialized?

I know mengram used a multiswitch in 2012 that used 13 & 18 volts.  It was a Zinwel 3402. Might want to look it up online. If it looks like what you have, send him a pm. He's a great guy.

Here is what I found to be the specs although it does not explain everything in detail.   E_V

So is this something that is built in a c band lnbf for polarity switching??  The guy I bought it from said it worked on FTA too. I paid $5 and would like to try it for switching between c & Ku but I sure don't want to burn up a $40 lnbf. Is that possible? Thanks

I am not sure, haven't been able to find a setup instructions for it. The part that says 'routs any input to any output using 13/14 Vertical or 18V Horizontal polarities set at the receiver' is a little confusing to me. Maybe Titanium will chime in and give some insight. He works in the industry. Surely someone will come up with the answer.   E_V

I would interpret that to mean that whichever voltage (13 or 18) is coming from from the receiver is routed to the proper output of the switch based on whether or not the 22Khz tone is on - which is the way the switch is supposed to work.
