How Far Will 2.5kW Reach?

This type of power and antenna should be mounted on a least a two story building and on top of a 12ft / 3.5mt pole. If this condition is met and the building is on high ground, then up to 50 miles is possible with high quality radio receivers, Expect about half this range with lower quality radio receivers.

1kW FM Transmitter Power

The transmitter power of this system is a straight, clean 1000 watts or 1kW. It's fully protected against over temperature and reflected power. in fact it will handle any level of reflected power at any phase angle for any length of time without damage. This is crucial for customers new to this in developing countries that make cable and antenna mistakes frequently. No matter how many antenna or cable faults there are, this transmitter will withstand them without any damage. More on the 1kW TRANSMITTER

4.8dBi Antenna Gain

The 5/8 antenna is a high performance narrow band vertical antenna which is designed to being mounted to the top of a pole. Because of this top pole mounting it's physically higher off the ground than side mounted dipoles etc. Due to this, even if it's lower gain than the side mounted type, it can have increased range, just because of the height advantage.

20 Metre (66 Feet) Antenna Cable

This package uses 66ft / 20mt of LMR400 antenna cable. The loss on this cable and plus the antenna gain actually results in an EIRP of 2500 watts, or 2.5kW EIRP.

FM Stereo Audio and Processing

The FM signal starts in the internal Veronica PLL which produces the super low noise and highly stable FM signal. You can find more info on this at in our 1W Exciter (PLL driver). Then the internal stereo coder and audio processor boards provide a loud and crisp audio signal on the listeners radio. If your more of an expert, you can if you want use an external processor such as Orban, Inovonics or PC generated MPX/RDS, the limiter and stereo coder we supply can be completely disabled.

Declaration of Conformity

European Union

We hereby declare that this equipment complies with;
ETS 300384 European Telecommunications Harmonised Standard when used with an audio compressor limiter supplied and tested by Aareff
EN 301489-11 V1.3.1 (2006-05) EMC Electromagnetic Compatibility when used with 1 meter AC mains cord supplied. If the installation engineer needs to extend this cord, this and the audio input cable should be no more than 3 meters in length to remain in compliance with EMC directive.
2006/95/EC Directive (2006-12) LVD Low Voltage Directive.

Equipment compliance is possible using equipment from and in conjunction from other manufacturers, but since this is beyond the control of Aareff Systems, Aareff Systems cannot or be expected to guarantee compliance in this situation.

2.5kW Maximum Range Chart

This graph is based on average maximum customer reports in some directions. Basically this shows the maximum ranges really ever recorded. Most of the reports were radio station listeners that phoned, texted, WhatsApp etc. into the radio station programs operated by our customers.
