10KW FM Transmitter — High Efficiency · Modular Design · 28" RU
Overview
The High Power 10kW FM Transmitter, available also at 12 kW power level, combines a very compact size (28" RU) with the most innovative technologies in terms of efficiency, costs and maintenance. A reliable solution, performing ease of use, high reliability and simple control. This high efficiency 10KW amplifier has an approximate consumption of 13600VA, so it pays for itself in a short period of time due to its low consumption.
Performance & Technology
RS-10kW is engineered to deliver superior sound quality your audiences will love. With the direct-to-channel digital modulator and built-in sound processor, it will ensure perfect audio fidelity. The DSP microprocessor allows the digital processing of the audio signal, giving higher audio quality and less distortion.
High Efficiency Design
Very high efficiency, more than 75% for a complete 10 kW transmitter, thanks to the latest LDMOS technology for power modules and Ultra High RF efficiency (>80% typ.) software optimized for each power level. This design achieves the lowest weight and dimensions in the industry, with lower device heating, lower room heating, lower space occupied and lower maintenance needed. Small dimensions and low weight reduce transportation costs and simplify logistics, resulting in longer component lifespan, reduced electricity costs, lower maintenance costs, reduced cooling costs and fewer fans.
Modular Architecture
RS Superior Modular Philosophy allows relevant advantages: the entire system benefits from the optimum characteristics of the base module VL Amplifier. Each VL Amplifier is a complete functioning module with its own power supply, ventilation, control logic and output filter. Each module can be connected and installed or tested as a single amplifier, and a single VL Amplifier can be put on air as back-up of a bigger transmitter.
Protection System
- OVER AND UNDER VOLTAGE DC, OVER AND UNDER VOLTAGE AC, RF AND POWER SUPPLY TEMPERATURE PROTECTION.
- RF COAXIAL OUTPUT OPEN OR SHORT CIRCUIT PROTECTION, WITH LONG WORKING TIME ON SHORT/OPEN LOADS AT ALL PHASE ANGLES WITHOUT ANY DAMAGE.
- INTEGRATED AC MAINS FILTERING AND INTEGRATED LIGHTNING PROTECTION.
- DELAYED ENERGIZED SYSTEM RESTART AFTER MAINS POWER BLACKOUT, PREVENTING PEAKS AND HIGH VOLTAGE VARIATIONS.
- SOFT CONTROLLED SEQUENTIAL START-UP TO REDUCE INRUSH CURRENT DURING OFF TO ON TRANSITION.
Audio & Smart Features
Directly feed the transmitter from the audio processor with a digital MPX signal sampled at 192kHz and enjoy pristine audio quality and seamless integration with modern digital studios. The support of MPX over AES ensures optimal signal transport and future-proof performance.

How Far Does a 10KW FM Transmitter Reach?
Coverage distance depends on transmitter power, antenna gain, antenna height, and local terrain. Below is our reference table based on a standard dipole antenna at 30m AGL over flat terrain.
5KW vs 10KW vs 20KW FM Transmitter: Which Power Level Do You Need?
| Power Output | Typical Coverage | Best For |
|---|---|---|
| 5KW | 60 - 80 km | Large metro area, multi-city regional broadcaster |
| 10KW | 100 - 150 km | Provincial / national broadcaster, wide-area coverage |
| 20KW | 150 - 200 km | National network, cross-border or mountainous terrain broadcast |
* Actual range varies with antenna height, terrain, and local RF environment. High-gain antennas can significantly extend coverage.
Factors That Affect Coverage
-
Antenna Height: The higher the antenna, the farther the signal travels. Mounting on a tower or hill dramatically increases range.
-
Antenna Gain: A high-gain directional or omnidirectional antenna multiplies effective radiated power (ERP) beyond the transmitter's rated output.
-
Terrain: Mountains and buildings reduce range; flat plains and coastal areas extend it. A 10KW transmitter over open water can reach 400+ km.
-
Cable Quality: Low-loss coaxial cable minimizes signal loss between transmitter and antenna, preserving your full 10KW at the radiating element.
"Our 10KW transmitter covers the entire Lagos metro area from a single tower site. The signal is rock-solid, even during peak hours."
Why Professional Broadcasters Choose Our Modular 10KW FM Transmitter
Running a 24/7 broadcast operation means zero tolerance for downtime, rising electricity bills, and costly maintenance calls. We engineered this 10KW FM transmitter around the real challenges you face every day.
FEATURE 1
Keep Your Station On-Air — Even When Components Fail
Every minute your transmitter is offline, you lose audience trust and advertising income. Traditional single-unit transmitters mean one failed component shuts down your entire station. Our modular architecture was designed specifically to eliminate this risk.
-
Hot-Swappable PA Modules
Replace a faulty power amplifier module while the transmitter continues broadcasting -- no shutdown required.
-
Redundant Power Supply Unit
Dual PSU design ensures the transmitter keeps running even if one power supply fails unexpectedly.
-
Intelligent Fault Isolation
The system automatically isolates a faulty module and redistributes load, maintaining full output power.
"If one module fails, the transmitter doesn't go off air -- it keeps broadcasting while you fix the problem."
FEATURE 2
Reduce Power Costs with High-Efficiency RF Technology
A 10KW transmitter running 24/7 is one of your station's biggest operating expenses. Inefficient transmitters waste power as heat, costing you thousands of dollars per year in unnecessary electricity. Our LDMOS technology changes that equation.
-
High-Efficiency LDMOS Technology -- Up to 80%
Advanced Laterally Diffused MOSFET transistors deliver industry-leading RF efficiency, converting more power into signal and less into wasted heat.
-
Smart Power Management
Intelligent load balancing across modules ensures each PA stage operates at optimal efficiency, reducing total power draw.
RF Efficiency Comparison
FEATURE 3
Easy Maintenance and Support Remote Control
Flying in a technician to your transmitter site -- especially in remote or rural areas -- is expensive and slow. Many stations in Africa, Latin America, and Southeast Asia simply can't afford frequent service visits. We designed this transmitter so your own team can handle most maintenance tasks.
-
Front-Access Maintenance Design
All modules, connectors, and serviceable components are accessible from the front panel -- no need to pull the rack or access the rear.
-
Modular Architecture
Swap out individual PA modules, PSUs, or exciter boards independently -- no specialist tools needed, no full-unit replacement.
-
Remote Diagnostics via Web Interface
Monitor forward power, reflected power, temperature, and fault codes remotely. Our engineers can diagnose issues via WhatsApp without an on-site visit.
"After-sales support is included: we set up a WhatsApp group with your team and our engineers to guide you through any issue -- step by step."
FEATURE 4
Reliability in Harsh Conditions
Many of our customers operate in Nigeria, Ghana, Kenya, the Philippines, and other tropical regions where heat, humidity, and dust are constant threats to electronics. Standard transmitters weren't built for these conditions. Ours are.
-
Tropical Climate Support
Engineered to operate reliably in high-humidity, high-temperature environments. Automatic over-temperature protection activates at 60°C to prevent hardware damage.
-
Dust-Resistant Forced-Air Cooling
Filtered airflow system protects internal components from dust ingress while maintaining efficient thermal management in enclosed transmitter rooms.
-
