Those on a tight budget and would like to save possibly hundreds of dollars on installation costs and those who would like to customize their car audio system may want to install the car audio system themselves. Whatever the reason, it is quite easy to install a car audio system and here are some tips. …
A radar jammer is a piece of equipment used to scramble nearby radar signals. Radar jammers are often used by drivers to jam the signals coming out from police speed detectors. The radar jammer is very similar to the Power Drainer and is the size of a small box. Radar Jamming as a Crime There …
A fractal antenna is a diamond-shaped antenna that maximizes the total amount of material within a given amount of space that transmits or receives electromagnetic waves. Fractal antennas do this by making each section of the antenna its own separate dipole. Because of this design, fractal antennas operate at many different frequencies and wavebands, allowing …
GMRS (General Mobile Radio Service) is a licensed radio service. GMRS consists of 16 UHF channels on FM, plus 7 channels that are shared with FRS. The maximum allowable power for a GMRS radio is 50 watts. The GMRS channels which are shared with FRS are limited to 5 watts of power. The use of …
In order to deter theft, the majority of major automobile manufacturers implement a car radio security code. When the car stereo is removed from a vehicle, the device will not be usable until the unlock or security code is entered by the car owner or authorized repair facility. Unfortunately, some models of cars and trucks …
UHF is an acronym for a band of radio frequencies often used to broadcast television signals. Mobile phones and satellite radio also use UHF signals. The letters ‘UHF’ stand for: Ultra High Frequency. UHF Frequencies Any radio frequency between 300 MegaHertz (MHz) and 3,000 MHz (or 3 GigaHertz) is considered to be in the UHF …
A circulator is a box-shaped ferrite device that has three or four ports and allows energy from one port to transfer to the next port in line. Circulators are usually used with radio signals but can also be used with microwaves, light, and other electromagnetic waves. This means that a radio signal that is being …
Traditional radio equipment works because all parties involved in the communication agree on what frequencies they will utilize. Traditional radio scanners work by scanning for and then listening to those frequencies. Trunking radios, on the other hand, constantly renegotiate the frequencies utilized for the conversation. This allows for more efficient utilization of limited frequencies because …
A loop antenna is one that is designed to receive radio signals more efficiently than other antennas. Loop antennas are considered more efficient than others because they are mobile, work with a wide range of frequencies, and use less electricity. A loop antenna’s performance is entirely dependent on its construction and placement, although other factors …
FCC ID stands for Federal Communications Commission Identification. An FCC ID is the number found in all computer hardware components. FCC ID numbers, usually found on the circuit boards, are helpful in finding information about the manufacturers of the hardware devices. An FCC ID has 2 elements. The first is a three-character Grantee Code which …
