High Frequency Radiation and Human Exposure - WHO
www.who.intMobile phone base stations may be considered as relatively low-power multi channel two way radio systems. They comprise transmitter and receiver systems and the transmit-receive antennas. These antennas produce radio frequency radiation and they expose people near them to electromagnetic radiation.
MFJ-949E Versa Tuner II Instruction Manual - RadioManual
www.radiomanual.infoIf your transmitter can not reach 30 watts, set it to the maximum power available. 7. After a low SWR is obtained, the transmitter power may be increased to any value up to 300 watts carrier or 300 watts PEP. Your VERSA TUNER II will reduce the SWR of most antenna systems to 1:1. In some cases, a perfect 1:1 SWR may not be obtainable.

cdn.ttgtmedia.comreferring to power, a decibel is defined as follows: X dB = 10 Log 10 (X/X0) Because path loss is an important quantity in defining the coverage and capacity of mobile radio systems, a useful unit used to compare different environments is to define the decrease in received power over a “decade,” where a decade corresponds to an

Low Power Consumption The system is built using highly sensitive low power consumption components, maintaining high receiver sensitivity, while consuming as little as one tenth the power of a standard FM system, dramatically extending battery life.
CONTAINS TWO SEPARATE AUDIO SYSTEMS - Elenco
www.elenco.comSection 9 includes the FM mixer, FM oscillator, FM RF (Radio Frequency) amplifier, AFC (Automatic Frequency Control) stage, and the FM antenna. The incoming radio waves are amplified by the FM RF amplifier, which is tuned to a desired radio station in the FM frequency bandwidth of 88MHz to 108MHz. These amplified signals are then coupled to the FM

www.ti.com• The antenna is VERY important if long range is important • A quarter wave antenna is an easy and good solution, but it is not small (433 MHz: 16.4 cm, 868 MHz: 8.2 cm) You can “curl up” such an antenna and make a helical antenna. This is often a good solution since it utilizes unused volume for a product.
ZS6BKW Antenna Revisited - from Sprat #130 - Nonstop …
www.nonstopsystems.comDiagram 1 shows the antenna, later to become known universally as the "G5RV". Like so many good ideas, it is so simple. It works as follows: On 20m the flat-top is three halfwaves long. Its feedpoint impedance is therefore low and because the open-wire line is one half-wave length on that band it merely transfers that low impedance to its other end
