What kind of antenna? First you need to decide on what type; A really simple answer to this question is to cut a wire to the resonant 1/4 wavelength. This antenna would be 3 5/16 inches of wire.

What is the perfect length of antenna for a radio signal of 100 MHz?
The half-wave, center-fed 'dipole' antenna is probably the antenna that's simplest to design, and easiest to build and operate. For 100 MHz, it's a single wire, supported at its ends and insulated from the supports, hung horizontally, opened and connected to a 75-ohm coaxial cable at its center, with an overall length of 4 feet 11 inches (1.5 meters).
Will a 27mhz cb antenna work on your uhf cb radio?
No, this is not a wise move to make. The antenna metals are not the same. you have to know that antenna metals are different within all Mhz. 2nd- The connectors are different. CB has a wider coax connector and Uhf us smaller. Radio Range/ distance will be less if you use a short wave antenna known as CB. Best to get a High wave antenna- UHF. 27 Mhz is cb radio and the waves are low and long (about 11 meters). 400-460 Mhz is UHF and the waves are high and short (about 67 centimeters). You would need a UHF radio antenna to get the best SWR. Installing a UHF antenna on a car it would require a proper uhf antenna and coax and drilling and using only a UHF Coax cable with the connector. Or buy the Uhf magnet antenna. They are hard to find in your local city and they are pricy because you cant buy them used or at cb shops. you will have to buy one online or go to a Junk yard and find a Police car that has one on top of car. You can Mod Coax cables only if its a UHF cable and antenna. Grounding a car UHF antenna in house can be difficult. Don't run ground to AC ground! you can damage radio. Run Ground wire to the dirt outside and dig a hole and fix with a little water and keep hot coax separated from ground on uhf. Best is to run this to Gutter on roof. Do not MOD CB coaxes with UHF antenna or mix with magnet antenna or CB, VHF, Marine radios. You will waste your time. 800 Mhz police antenna will be your closest match if you decide to do this. It goes by the wave and wave length. Keep Digging
What is the difference between 800 mhz and 900 mhz radios?
100 MHz
How long should an antenna be to absorb radio waves well and red light?
A vertical antenna, like a piece of wire, connected directly to the radio, works well if it's 1/4 of the wavelength of the signal being received. If it's a horizontal wire hanging between a couple of trees, with a coaxial cable connected to a gap in the middle of the wire, then it works best when its overall end-to-end length is around 1/2 of the wavelength. 1/4 wavelength in feet is around: (246) divided by (frequency of the signal in MHz) 1/2 wavelength in feet is around: (492) divided by (frequency of the signal in MHz) The frequency of red light is around 462,000,000 MHz. So for good efficiency, the half-wave antenna should be about 0.00000107 foot long, or 0.0000128 inch. If you have a radio receiver capable of tuning to the frequency of red, I'll personally come help you trim the half-wave antenna to pick it up. In fact, I'll build you a by-George 100-element Yagi !
What is frequency band for FM?
30 Mhz - 300 Mhz
Will GSM 850 900 1800 1900 MHz work in US?
In North America, GSM operates on the primary mobile communication bands---850 MHz and 1900 MHz. GSM-1900 is the primary band used in urban areas with 850 as a backup, and GSM-850 being the primary rural band.
Claculate the length of the dipole antenna at 450 MHz?
245
What are the specifications for the Nokia N95?
The Nokia N95 is a 3G dumbphone. It supports 2G networks on the 850, 900, 1800 and 1900 MHz bands, and 3G HDSPA on the 2100 MHz band for the international version, and on the 850 and 1900 MHz bands in the American version.
when The AN/PRC-152 handset comes with two removable antennas. Identify the TWO types of antennas and their corresponding frequency ranges.?
-30 to 108 MHz blade antenna-30 to 512 MHz whip antenna
How can you find out if an unlocked cell will work on Verizon it uses 2 g gsm 850 900 1800 1900 mhz and 3g wcdma 850 2100 mhz for frequencies?
In theory, it should. See the table in the related link to Wikipedia. Verizon doesn't use 700 or 1700 MHz - but does use the others you've listed.
What frequency do cell phones travel at?
common frequency in North America are 850 and 1900 MHz
What MHz is the Nokia 5800?
2G Network: GSM 850 / 900 / 1800 / 1900 3G Network: HSDPA 900 / 2100 HSDPA 850 / 1900
What are the differences between dual band and quad band phones?
Basically, the difference lie on the frequency being used or supported. For GSM dual band phones, the frequencies that is can support are 900/1800 MHz or 850/1900 MHz; for tri-band phones, the frequencies are 850/1900/2100 or 850/1700/2100 or 900/1900/2100 MHz or 900/AWS/2100; and for quad-band phones, the frequencies are 850 / 900 / 1800 / 1900
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.
What is the relationship between frequency and antenna height?
For horizontal antennas operating below 30 MHz the optimum height is half a wavelength, so the height in metres would be 149.9/Frequency in MHz.
Why High frequency reduce the size and weight of components?
The concept is, greater the frequency less will be the size of antenna and weight. For example the Mobile Phone uses the half wave dipoles antenna. There is no exact formula for calculating these antennas. The problem is that there are several factors that affect the antenna. Fortunately there is a starting formula for these types of antennas. For center fed, wire dipole antennas, the formula is length of antenna = 468/freq (MHz). Mobile phone in GSM working on the frequencies 900 MHz and 1800 MHz so put the values in the formula you get your answer. If you move further in the frequency band the size will be more small.
What is the optimum length am antenna?
[ (234) divided by (station frequency in MHz) ] feet, hanging vertically.
