Why Dipole Antennas Are A Half Wave Long? The fundamental resonance of a thin linear conductor occurs at a frequency whose free-space wavelength is twice the wire’s length, i.e. where the conductor is 1/2 wavelength long. Dipole antennas are frequently used at around that frequency and thus termed half-wave dipole antennas. Why are antennas half
Will My Antenna Break In A Car Wash? It is very possible depending on the car wash you are using and the design of your vehicle to have your antenna or other exterior components damaged. … The weight of the brushes and sponges in the car wash alone are heavy enough to snap the antenna
Can Satellite Radio Antenna Be Used For GPS? Users do not need antennas for GPS service because the devices are readily equipped with the right antenna, albeit quite small. Satellite radio users, however, need antennas to narrow down the exact signal spectrum from the communications satellite. Does Sirius radio have GPS? Yes we do. In
Are Antennas Passive Or Active? An active antenna is an antenna that contains active electronic components such as transistors, as opposed to most antennas which only consist of passive components such as metal rods, capacitors and inductors. Why is antenna a passive device? An antenna is a passive device which does not offer any added
Why Did I Lose Channels On My Antenna? It’s possible that the TV signal for the channel you lost was stronger when you originally scanned than it is now. There can be many reasons for this, including time of day, atmospheric conditions, electrical interference, or a weaker signal due to obstacle or lower transmitter power.
What Happens If I Remove Car Antenna? Whether you have a telescopic or fixed antenna on your car, over time it can wear out or become bent. A damaged or malfunctioning antenna can prevent you from listening to the radio in your car, and takes away from your car’s overall appearance. Does a radio need
Will A GPS Antenna Work Through Plastic? GPS signals travel by line of sight. This means that they will pass through clouds, glass, and plastic, but they won’t pass through most solid objects, such as buildings or mountains. Can a GPS antenna be covered? So, the GPS antenna can be safely encased within those materials,
Do I Need An Antenna For Sirius? In order to receive satellite radio, you need a special antenna. Your standard car radio antenna won’t cut it because, unlike FM radio and HD radio, satellite radio and FM radio aren’t broadcast on the same frequency bands. Where do I put an XM antenna? If you are
Why Is My Antenna Not Picking Up Channels? Your cables may be loose. If you have loose cables, you’ll most likely get no signal or a spotty signal. So make sure your connections are tight at your TV and your antenna. While you’re checking your connections, also take a look at your cables to make
How Do You Reduce VSWR? One technique to reduce the reflected signal from the input or output of any device is to place an attenuator before or after the device. The attenuator reduces the reflected signal two times the value of the attenuation, while the transmitted signal receives the nominal attenuation value. How do you
