Any number of situations may call for these measures but the antenna system must still work! Federal law backs up that requirement for licensed Ham radio stations. The power of group pressure. In any event, a brief presentation to the HOA Board resulted in approval. However I keep them very low profile to keep the neighbors happy anyway.

This W RF amplifier circuit provides an appropriate power boost with an input of watt. Tower are 30 meters high will send signal surrounding air should be around 15 km. Of course the recreational purpose also exists and the children will adore to have a transmitter that allows to speak for a radio FM placed at distant place and like this pretend the secret agent. FM Transmitters Powerful microtransmitter that can cover 3km range. In our case the output power is about mW depending on the input power of 10mW and 9V battery power supply.
End-fed, half-wave antennas EFHWs are a half-wavelength long and are resonant antennas on the band of interest. Generally, they are not usable on bands for which they are not a half wavelength long. End-fed wire antennas are a different beast.
FM Transmitters This simple mW transmitter broadcasts audio on With good dipole antenna transmission range up to 4km is possible. Frequency is selected by adjusting R1 potentiometer.
