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 85km is possible with high quality radio receivers, Expect about half this range with lower quality radio receivers.

This bold looking 19 inch unit is made to last. Constructed from steel and power coated in black, it's here to stay. The internal boards and modules are no exception. Driven by the world renowned Veronica® PLL board to give super low noise and RF stable performance. The limiter and stereo coder can be completely disabled if you want to use an external processor such as Orban, Inovonics or PC generated MPX/RDS. More info on the 1000W Transmitter
As an optional extra this transmitter is available with dynamic and programable RDS fitted. If you want RDS option please (rds-upgrade) ADD TO CART

Almost like magic the 5/8 WAVE ANTENNA transforms the transmitter power by 3 times to 2.5kW and this is even after taking the cable losses into account. This transformed signal is effective radiation, what it means is that if you stand at the horizon many miles away, the signal voltage with this antenna will be exactly the same and indistinguishable from the signal voltage of a 2.5kW transmitter using just one dipole antenna. The power is effectively identical, hence the name EFFECTIVE ISOTROPIC RADIATED POWER (EIRP).
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 over 2500 watts.
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.
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.
The following list are the FCC technical requirements for FM broadcasting. We confirm and verify that this transmitter complies with the technical requirements.

This graph is based on average customer reports in some directions. Basically this shows the typical 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. Range is very difficult to predict as there are many factors that effect it. More info on FM Transmission Range
