Wineguard SensarPro

We are at a campground where two of the major network TV channels (NBC and CBS) are very weak. CBS won't come in until after sunset, if at all. Due to many good reviews, the other day I purchased a Wineguard SensarPro power supply to replace the original power supply for my batwing antenna (which has the wingman). I was hoping the SensarPro's gain feature would help with receiving the two weak channels (both VHF).

However, after installation the SensarPro showed no signal at all for both channels of concern. Moving the gain up incrementally to 20 did not help (possibly because it could see no signal to amplify?). I could still get most of the other channels (the stronger signal channels) that I was receiving before. All the features of the SensarPro such as scan, seek etc seemed to work, but now no signal for the above-noted channels (both VHF).

I reinstalled the old power supply and now I could receive NBC clearly and CBS was back pixellating just like it was before I installed the SensarPro.

Has anyone else noticed something similar to this with the SensarPro for weak channels.

I can see where the SensarPro's features would help with optimally pointing the antenna to get more channels but I'm not happy if it is less effective than my original power supply for pulling in weak channels. I wonder if the SensarPro introduces enough more noise to drown out weaker channels.

Or perhaps my new SensarPro is defective?
  • My experience was opposite of yours.

    Does the peaking function work? If so, its seeing the signal.

    You may want to turn the gain down to 1-2 and retry; you might be over driving the tv input.
  • I suspect you may have a defective SensarPro. Ours has worked quite well in bringing in signals in some previously problematic areas. In some locations, I've even had to turn down the gain to keep from over driving the TV.
  • I would start by checking the connectors.
    Measure the voltage at the power supply. Then measure the voltage at the antenna.
    Excessive voltage drop can under power the booster. Low voltage can indicate high resistant connections along the way which can effect the signal strength.
