 While this type of cabling is less expensive, there are some drawbacks. For cellular and PCS frequencies, on average, RG6 will lose 6-10 dB of signal per 100ft. Depending on

the actual length of cable you use, this can sometimes provide more signal loss than the outside antenna provides in gain. Remember, you want your Cellular Jammer to receive the highest level of signal

possible. For this reason, it is recommended that runs using RG6 should be no longer than 50 or 60 ft. For most other in-building cell phone signal boosters LMR-400 50 Ohm Coax is the standard. In

comparison, while LMR-400 is more expensive and thicker, it only loses about 3-6 dB per 100 ft for cellular and PCS frequencies respectively.
Based on this, LMR-400 can be run further than RG6 before there is a decrease in system performance. For all three-piece systems it is recommended the amplifier be installed as close to the

external antenna as possible, using the shortest cable possible. Ex. If the external antenna is installed on a roof, it is recommended the amplifier be installed in the attic as opposed to the

basement. The shorter the cable length between the external antenna and the amplifier, the better. Remember that there is no separation requirement between the antennas and the amplifier, only

between the antennas.An amplifier is majorly used to increase the power of signal. It is an electronic audio device with an input signal either in the form of voltage or current. There are wide

range of electronic amplifiers which are being most commonly used in radio and also television transmitters.Functional error: the process of testing and evaluation services not following functional

error, a failure is not by any of the following: no endless repetition of the links; not appear online and need the full functionality can not be completed off-line phenomenon; not of a business

can not access the phenomena, such as "HTTP404 error, HTTP500"; not appear part content is empty; not a "server busy", "request not found" error prompt; not appear directly linked to the existing

business content network service ; not appear linked to other WAP portal websites; the page must provide a return to Channel Home Monternet and game links; links and text must be consistent;

business basics can not be achieved; other significant features of the error. The worker should pay attention to self protection during manufacture process of cell booster .Confirm the power supply
