10000W EIRP is a formidable power level, this is just over 6kW ERP which is the power level required by the FCC for a class B1 and C3 stations. You can calculate EIRP and ERP along with antenna gain online here. According to our customer reports distances of up to 138km have been achieved in some directions using 10kW EIRP. In reality on average terrain with average quality radio receivers the normal usable distance would be about half this. For more accurate distance predictions we can make you a radiation plot using satellite elevation data like these
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
The 100KW, 50kW, 25kW, 12.5kW and 10kW all use this same 8 way folded dipole broadband antenna. 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 aluminum 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 15 times !!!
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

The coaxial antenna cable used on this system is LMR600. This is super low loss with only -1dB of loss over 40 mt (at 100 MHz). This is the reason that most of the power developed by the amplifiers is transferred with ease to the huge gain antenna stack. The cable is robust but at the same time flexible with an external diameter of about 13mm / 0.5 inch. Both ends of the cable are fitted with high powered Teflon DIN7-16 connectors.
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.
47 CFR Chapter I Federal Communications Commission sections:
• 73.1560, 2.1046 RF Power
• 73.1545, 2.1055 Frequency Stability
• 73.317, 2.1049 (e)(3) Emission Limitation, Emission Mask

• 73.317, 2.1057, 2.1053 Emission Limits, Field Strength of Spurious Emissions
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
