Bypassing antenna

We are currently in a location where we can only pick up a couple channels with our winegard antenna. We purchased an additional antenna that can be raised higher attempting to reach more channels. Can this antenna be hooked up to the satellite connection so the existing rv antenna doesn't have to be modified? If not, how can we connect this antenna to enhance the rv antenna without interrupting the existing connection?
Thanks in advance

Welcome!!!

Makes and models would help.

IF you are talking about a Winegard batwing style antenna, it has an amplifier within the antenna itself and requires 12V supplied by the small power supply usually mounted on the wall or ceiling of the trailer/motor home, it has an Off-On switch and often a small light. It has to be turned ON to use the antenna, with the antenna turned toward the signal source for better reception. The amplifier is turned OFF to used a park cable connection in most cases. Check all connections, and check for the 12V on the coax to the antenna and reconnect everything after cleaning.

We have no info for the proposed additional antenna so any comments on it are not possible.

Note that most (but not all) OTA (over the air) signals are now digital and if your TV does not have a tuner capable of converting a digital signal, then you will require a digital-analog signal converter in series with the antenna feed in order to see all the available channels. With a converter in place, the TV is then set to channel 3 or 4 and the channel selection is made by the converter by using a remote control that comes with the converter itself. There is also a small antenna made specially for the Winegard Batwing and mounts directly under it. It improves the reception of digital signals greatly as most are now in a higher frequency range than the original batwing was designed for.

You can connect the new one to the satellite cable, provided it is not being used for a satellite operation. It is only a coax cable after all. But will it work better? Who knows as we have no information on it, it may require a power supply or it may not!! You may require a digital converter or not!! Older TV's with the big picture tube will require a converter for sure. The original bat wing was one of the best antennas available.

More than you wanted to know but... HTH

If you do have satellite tv, the satellite cable will go to the satellite receiver, not the tv.  If you don't now have a satellite receiver, you could find the end of the pre-wired coax and run another length of coax from there to the tv.

Do you have a park cable inlet as well?  That coax should be wired to the antenna/cable A/B switch and from there to the tv set. You can use that and set the A/B switch to cable (which would actually be the new antenna).

The Winegard Sensar (And most of their other models) are powered amplified antennas.  That is the RV sends 12 volts up the coax to power it

SOME antennas also need this. SOme do not and SOME object to it and will blow the fuse,.

Better to hook your External (if not an amplified model) to the Park Cable IN
