    Being I have a CM7777 just sitting around I was wondering if it would work to pull in the weak signals of my Winegard Sensar OTA antenna.

    Will it help or hurt?

    The CM7777 would have to installed on the TV/OTA adapter side of the Winegard power injector inside your RV instead of on the mast as designed. That means it would also be amplifying any induced signal noise of course. It could also over drive the TV/OTA adapter. I have Winegard's SensarPro combined 10 dB amplifier/power injector installed on our Sensar III antenna, and there have been times I've had to dial down the gain on it for the best reception. And as you know, the CM7777's 30 dB gain is not adjustable...

    In the past I have installed both pieces of the CM7777 at my antenna (indoor antenna in an apartment) and it worked. I was thinking of installing this setup in front of the 4 way splitter that is in one of my compartments. I have it setup temporarily just to see if it will work while I am parked at home and it works. But all of my local OTA towers are close by so I cannot tell any difference between using the CM7777 or not.

    Well, if you have a convenient place to install it where it can easily be bypassed, sure, give it a try.

    For the ease of switching back and forth I have a spare A/B switch to use.
