5000W EIRP is an ideal power level for broadcasting to a large city, it can also typically reach up to 70 miles with excellent quality radios. With typical quality radios about half this range would be normal, say 35 miles. We can give more accurate predictions on range using satellite elevation data like this example on our Facebook page here
The crisp clear FM signal starts in this unit which provides 1000W super clean output in stereo with audio processing and limiting. For a small, but with a need to be quite powerful radio service, a big town for example, this transmitter is just the ticket with everything required included. More info on the 1000W Transmitter
The 100KW, 50kW, 25kW, 12kW and 10kW all use this same 8 way folded dipole broadband antenna, the one in this package is the baby brother 4 way version. The simple reason is, because it's simply amazing. It has high bandwidth with an SWR or less then 1.2 from 87.5 to 108 MHz, most dummy test loads struggle to manage this. Many coaxial cable lengths, especially the cheap Chinese rubbish struggles to maintains less than 1.2. So this is the reason this antenna is gold, metaphorically speaking, made out of aluminium and stainless steel. I forget to mention, it does not rot or corrode even in coastal areas. But most important, it MAGNIFIES the signal radiating to the horizon by over 7.5 times !!!
If you want to see your station name and more scrolling across the car radio display add the RDS Option, 'Add To Cart' rds-upgrade in the price panel.
This RDS Option is not just ordinary RDS, it is fully programmable dynamic RDS. This means the transmitter can be connected to a PC by a USB cable. The transmitters RDS circuit will pick the Artist and Song name from any folder on the PC disk drive. This folder is easy to set up in the DJ playout software, like Zara Studio etc. Detailed information HERE.

This package uses 130ft / 40mt of LMR400 antenna cable. The loss on this cable and plus the antenna gain actually results in an EIRP of over 5kW.
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
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.
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.
