Some electric powered antennas were made to not totally retract. 4 to 8 inches retracted size is about normal.
Some electric powered antennas were made to not totally retract, 8 to 10 inches is about normal retraction length.
considering that eclipse is going to be a huge blockbuster i would say all cinemas would show it.
Try turning the radio off before turning the car off. If this doesn't work, check the assembly at the base of the antenna for a sensor switch for gunk and clean it off. Don't ask me where it is, because I don't have the schematics for the antenna assembly on a 1992 Cutlass Ciera handy at this moment. If this doesn't work, the easiest "fix" is to wait until the antenna goes all the way up, then clip the power lead to the antenna motor. Just make sure you don't clip the antenna lead. This will keep the antenna up all the time. Next cheapest route is to replace the whole antenna assembly, motor and all. I would recommend getting a cheap $5 standard antenna from a local auto parts store and do away with the "convenience" of the automatic retractable antenna.
You would need an HDTV antenna when you can get all of your channels and when you get bad signals. This is when the picture don't play clearly and it has bunch of lines.
If the TV antenna was built for the correct frequency, it would work but my second thought is do you want the antenna to send a directional signal? I would think a "omni" signal (all direction pattern) would be a better choice. Most TV antennas are directional.
the little motor could have gone bad
there is a cable inside the housing. that cable must have snapped (common) i would replace entire antenna, with either new power or save about $80 and put a mast style in
The power of the signal, as perceived by the receiver, will be lower with an omnidirectional antenna. This is because the omnidirectional antenna is transmitting in all directions, while the directional antenna is transmitting in only one direction.Think of the directional antenna as a lens, focusing proportionally more power in a smaller space.
FM is out on your stereo, i had same issue.
Nothing at all
Then the total phase of the eclipse would last longer. Also, it is more likely that there is a total phase at all.
You can buy high gain antenna's for your task at a number of online shopping sites, such as amazon.com. I would suggest going there to fulfill all of your needs.
An omnidirectional antenna can be practically implemented but an isotropic antenna cannot be implemented practically. An isotropic antenna resembles an ideal antenna with ideal values for all parameters.
