Tuner 2 no signal

I recently had a Winegard Sk-3005 dish on my RV that died. I had to upgrade to a SWM3. All is setup dish wise but the DVR receiver tells me there is no signal on tuner 2. This dish is supposed  to have only 1 cable to the receiver. I can't figure out what is wrong. Please help. Thanks

What model is the box you are trying to use?

Do you have a Deca on the setup?

Have you verified dish and multiswitch type when running satellite setup?

I have a HR24 box & I've done all the setup changes. I don't know what a Deca is.

Hi @Widow, we'll be happy to help with your RV setup.


The DECA is a small white box that attaches to the back of some receivers. It allows them to connect to the internet for optional features like on-demand.

In your case, you have an HR24 so it's not needed and you'd want to make sure one is not connected.


Since you're changing to a SWM dish, also make sure there is no B-Band Converter(BBC) connected. This is a small filter that would normally be connected to the Sat-in jack on the back of your HR24.

Your old dish may have required one of these but the SWM does not.


Aside from that here are a few other things to check:

  • The SWM dish also requires a power inserter. This is a small box that plugs into a power outlet and has 2 coax connections.
    • "Power to SWM" goes to your dish.
    • "Signal to IRD" goes to the HR24.
  • As Juniper mentioned, check the switch type on your receiver's satellite setup menu. It should be set to SWM, not multi-switch.
  • Make sure the coax cable is plugged into the Sat in 1 jack on the HR24. Sat in 2 won't work


Please let us know if this helps or if there are any further questions.
