How do you filter rf signals that distort television reception from a rooftop antenna?
There are a number of steps that you can take to prevent this distortion from occuring. But in order for you to know what to do, you should specify a few things, first:
a) Do you have an antenna signal amplifier?
b) Is it just one or two channels being affected, or is it all of your channels being affected?
c) What channels and ranges does your antenna receive?
d) What sort of distortion is it? Are adjacent channels bleeding into this one? Are there horizontal streaks and lines appearing? Or is it just an entire screen filled with noise? If all of your channels are affected or wiped out and you have an antenna signal amplifier, it may be that your amplifier's transmitted signal is too strong.
Also, it could be interference from an adjacent channel or the FM band. In this case, you may need a bandpass or a bandstop filter.
To get a bandpass or bandstop filter, you should probably turn to an electronics provider like Tin Lee Electronics (www.tinlee.com). You can also contact them about your problem and they should be able to help you solve it. In any case, if you could specify the above information, it would be much easier to find an answer to your problem.
Short answer: Yes! Longer answer: Digital TV and Analog TV share much in common; they are both radio signals, and in the same bands -- in fact the channel number assignments for the physical channels are identical. Your rooftop antenna picks up the radio signal no matter what is encoded on it. It is up to the receiver (your converter box, f'r'instance) to make sense of what comes from that antenna. Select a VHF/UHF type.
The reason cell phone reception is worse in a car is because the car's metal frame and skin act as a "faraday cage" which blocks and grounds out signals that are inside and outside of it. If you use a rooftop antenna it will get the signal out of the car. Many new cell phones only put out around on tenth of a watt, compared to in the old days when bag phones, if you…
How do you replace the rooftop antenna bezel that the antenna screws on to for a 2000 Mercury Cougar?
You will need to remove the overhead lights inside the car to do it. Pop out the lights with a flat head screw driver and disconnect the chords. Then look up and you will see a screw holding the base of the antenna to the hood. (Make sure you've unscrewed the antenna from the base though). Unscrew that and it should pop right off.
