500 Watt ERP FM Transmitter System

500 Watts Effective Radiated Power

500 WATTS Effective Radiated Power - The combination of 200 watts amplifier power, 20 meters of foam grade LMR400 and the high powered 4.8dBi gain antenna results in a radiated power of 500 watts (0.5 KW). To a listener at the horizon this is equal and identical to the signal received from a 500 watt transmitter with a single dipole antenna.

Simple Set Up

Instructions are supplied to show the station engineer how to set this system to any frequency from 87.5 to 108.0 MHz. However, when we assemble this system we have to test and set it to some frequency, please select from the box in the price panel that you would like it set to on delivery.

Everything You Need

This system includes everything you need to get the radio transmission side of your station up and running on delivery. The only thing you need to provide is a pole, mast or tower to put the antennas on and a standard stereo line (0dBm) audio signal from your studio or link equipment.

What's In The Delivery Package?

The package that's delivered to your door includes:

19" Rack FM Stereo Exciter with Limiter
19" Rack 200W Amplifier
20 Meter Foam Grade LMR400 Antenna Cable
5/8 Antenna or 2 Way Stacked Dipole (+4.8dB Gain)

FM Stereo Exciter with Limiter

This is a great looking unit with intense blue LEDs, this produces the high quality FM stereo signal at your chosen frequency. The signal is excited up to 1 watt of RF ready for further amplification. 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. This unit complies with European standards ETS 300384 for R&TTE, EN 301 489-11 for EMC and (LVD) 2006/95/EC for safety

200 Watt Amplifier

This produces 200 watts of transmitter power and will operate with ease at full power 24 hours a day non stop in any country and with any AC voltage in the world. The amplifier has a neat little meter on the front panel lit up with intense blue LED's to indicate forward and reflected power. The amplifier is fully protected from poor SWR and return loss of level for any duration of time.

20 Meter Antenna Cable

20 Meter Antenna Cable - This cable is high quality using foam dielectric and carries the radio signal 20 meters to the antenna with only a loss of 0.8dB, this would normally be used for stations with towers, or masts of 15 meters in height.

2 Way Stacked Dipole or 5/8 Antenna (+4.8dB Gain)

2 Way +3dB Stacked Dipole or 5/8 Vertical Antenna (+4.8dB Gain) - The two way, tier or stacked dipole package includes two dipoles, phased leads and splitter box. Alternatively the 5/8 with the same gain is just as formidable. Both antennas multiply the power from the antenna cable by 2.9 times horizontally to the horizon making sure maximum signal is efficiently put in the right place and not wasted into space or ground..

20 Years, Still Here

Over the last 20 years in Africa and Middle East alone we sold our systems into Congo, Uganda, Liberia, Zambia, Yemen, Rep South Africa, Oman, United Arab Emirates, Tanzania, Southern Sudan, Kenya, Ghana, Gambia, Nigeria and Niger. Our transmitters are very popular in very hot climates as they handle the heat and the dust very well under 24/7 operation.

Power Upgrade Compatible

The advantage to using a separate amplifier is that if you need to upgrade to a bigger system you don't need to buy the driver, set up the audio and other baseband signals again, all you need to do is buy an bigger or more amplifiers to add to your driver. We can give you more advice on this if you contact us.

Our Passion for Radio

We have tried to think of everything you will need to save you time when doing the installation. The package also includes, antenna mounting brackets, nuts and bolts, even the cable ties to strap your antenna cable to the mast. All you need to provide, is a tower or mast (at least 15 meters in height) to install the antenna system on and a standard line level stereo audio feed from your studio mixer or link.
