Mobile 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.

If 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.

referring 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

Section 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

• 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.

Diagram 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
