What is an ultra wideband antenna?
Antennas can be tuned for specific frequencies to increase their gain. These types of antenna are sometimes referred to as narrowband. An ultra wideband antenna works for a lot of frequencies around what is called a center frequency. For example, if you had a narrowband antenna centered around 10 megahertz it might work for frequencies from 9 to 11 megahertz for example. If it were wide band it might go from 5 to 15 megahertz, and so forth. The bands are clustered around specific center frequencies for different applications.
Where did the antenna go in modern phones?
Modern digital cordless phones use high frequencies - the length of the antenna is so short at these frequencies that its whole length can be incorporated inside the casing of the phone. The length of the antenna is 300 divided by the frequency.
Can you replace an XM radio antenna with any other antenna like a 3ft hard cb antenna?
You can replace an XM radio antenna with a CB antenna, a ham 40-meter mobile antenna, a cellphone antenna, a GPS antenna, a TV antenna, a wire coat hanger, a 6 GHz microwave antenna, or a chain of paperclips. However, since none of them is optimized to operate at the frequencies of XM radio, like the XM antenna is, none of the others will work as well. Most of them will likely be so inefficient at the satellite radio frequencies that when you use one of those, you hear nothing at all on your radio.
What would be the purpose of connecting a parallel-tuned circuit into an antenna circuit?
The parallel-tuned filter in antenna circuit rejects only the undesired frequencies.
How does a digital antenna differ from a regualr antenna?
A digital antenna offers a clearer sound and signal than a regular antenna. There is no interference or static. However, while an analog antenna can get the signal through a hill, the digital antenna must be able to see the broadcast tower.**************************************************************There is no difference. An antenna is designed for a particular frequency or band of frequencies. The mode of modulation is totally irrelevant.
Compare CB radio and VHF radio?
Yes, but not very effectively. VHF and CB radios are on different frequencies and therefore for best efficiency require different length antennas. You might be able to receive with the CB antenna, but transmitting will result in a high SWR and possibly overheat, shutdown, or destroy your VHF radio.
What are the common shapes for antenna reflectors?
A lot of parabolic reflectors are used in antennas, particularly with frequencies in the microwave region. There are a few other shapes, but they are infrequent choices for antenna designers.
Is the k40 CB antenna a marine band antenna and if not will it work with a marine band raido?
The K40 will not work as a marine band antenna, as it is "cut" (optimised) for 26-30Mhz. The Marine Band of frequencies is usually found 156-174Mhz.
What is a horn antenna?
A horn antenna is an antenna that consists of a flaring metal waveguide shaped like a horn to direct radio waves in a beam. Horn antennas are used as antennas at UHF and microwave frequencies that are above 300 MHz.
How can you tell the difference between a CB antenna and a VHF antenna?
The CB antenna is made for a limited band of frequencies and the VHF is a wide band antenna made for higher freqs. A CB antenna will not make a good tv antenna. A CB ant. is mounted on the vertical and tv ants. are mounted horiz. in the USA. VHF antennas are much smaller as they are for higher frequencies. Usually, they have many elements (rods) and will go from long in the back to short in the front. Certain CB antennas (beams) are mounted horizontally, but all of the elements are roughly the same length - and about twice as long as a VHF antenna. The elements on a horizontal CB antenna are roughly 18 feet from end to end.

What is broadband antenna?
A broadband antenna is one that works with a large range of frequencies. Broadband antennas can be used with a TV or a wireless computer network. Different types of broadband antennas include directional, patch, corner reflector, and Yagi.
