The transmission range of the transmitter used with an high gain antenna can be typically 12 miles. It is available as an MPX Version or an FM Stereo with Limiters Version. In addition to this you can also use it with 13.8V DC (4.5 amps or more) or 90 to 260V AC, it will work on any of these power supplies. The Stereo Version with Audio Compression and Limiting gives access to the MPX signal allowing any external RDS units to be interfaced easily.
Any frequency between 87.5 to 108 MHz can be accurately programmed on the dip switches located on the underside of the unit and locked up to meet the broadcast spec in less than 5 minutes. By adjusting a small pre-set control inside the power amplifier unit or the 1W drive unit the RF power output level can be set anywhere from 1W to 30W. Jumpers also located on the underside panels allow the audio pre-emphasis to be easily selected to the correct time constant of 50uS, 75uS (USA) or none.
The double stacked dipole has the benefit of 4.7dBi of gain and broadband operation. This is achieved using a specially designed splitter box to feed each dipole antenna with the correct RF signal phase. Providing the antenna is mounted correctly the SWR is less than 1.8 across the whole band from 87.5 to 108 MHz. This antenna system never needs tuning, just put your transmitter on any frequency from 87.5 to 108 MHz and switch on.
