How Far Will 100kW Reach?

This is about as big as it gets, there are not many systems bigger than this and even if there are, it's pretty difficult to exceed the 200km distance with any amount of power due to the earths curvature. With the antennas mounted on a high mast on high ground we have had reports from clients saying they have received calls from listeners up to 200km away. Admittedly, this distance is the extreme limit of 100kW, but is absolutely possible. Normal reception would be about half this clocking in about about 100km when you take the average radio, terrain etc. into account. But remember, power is not always about distance, power is sometimes required to penetrate the dense construction in some cities with tall concrete and steel buildings. Some of the large mega stations in the US use this power level, in the Los Angeles alone KBIG, KLOS and KTWV use this power level.

8kW FM Transmitter Power

To achieve 100kW EIRP only 8kW of transmitter power is needed if the correct antenna is installed with high grade coaxial cable. The 8kW of transmitter power comes from 8 separate 1kW amplifiers that are driven by a distribution amplifier and Veronica® 1W PLL driver. All our big systems above 10kW EIRP are configured this way using more than just a single 1kW amplifier. Due to this a complete shutdown or signal failure can only occur if the 8 amplifiers (1kW each) go down at exactly the same time, this is nearly impossible with super high odds. So if you need system reliability and a station on air, always, with no breakdowns, 8 or more if possible, 1kW amplifiers are perfect.

12dBi Antenna Gain

In these systems the antenna is everything, you must treat the antenna like your best friend, even a brother (sister too! for the pc sensitive). The antenna just looks like lumps and rods of aluminum screwed together, and it is! but it is much more, the antennas length, shape, installation and height dictate if you signal is going to do tens of miles or less than one mile. The antenna is more important than the transmitter and amplifiers. This antenna system uses eight folded dipoles optimally spaced to produce 12dBi of gain. Cut short, this multiplies the signal pointing to the horizon by 12.5 times resulting in 8000W EIRP transmission signal.

RDS - Radio Data System

As an optional extra this transmitter is available with dynamic and programable RDS fitted. If you want RDS option please ADD TO CART above

40 Metre (130 Feet) Antenna Cable

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.

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.

United States

The following list are the FCC technical requirements for FM broadcasting. We confirm and verify that this transmitter complies with the technical requirements.

100kW Maximum Range Chart

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
