tv tuner problems

I just added a tv tuner to my factory nav farenheit 5r I have two used antennas but the channels are not coming in good sould what should I do try some better antennas or get a better tuner.

I've personally never had GREAT experiences with any of the cheaper TV tuners available. The best ones I have see are the ones such as the Pioneer GEX-P5700TV, or Alpine TUE-T151, etc. which both must be controlled via their respective companies head units. I highly doubt that different antennas will make much of a difference, but it may be worth the shot if you are trying to avoid spending the money that the other tuners would require.

I have never had anything I would consider good with pretty much any tv tuner. Think about it. How good do rabbit ears work on a tv in your home? You may be able to find a good diversity antenna but you will still be about the same.Certified Security Specialist

Always check info with a digital multimeter.

I promise to be good.
