1600 WATT ERP FM TRANSMITTER SYSTEM
19" RACK STANDARD PRO-RANGE
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.
This package includes:

- 19" Rack FM Stereo Exciter with Limiter
- 19" Rack Amplifier Splitter
- Two 19" Rack 200W Amplifiers (400W)
- 19" Rack Amplifier Combiner
- Two 20 Meter Antenna Cables
- 4 Way +6dB Stacked Dipole (+7.7dB Gain)
1600 WATTS Effective Radiated Power - The combination of 400 watts amplifier power, 20 meters of LMR400 and a 4 way stacked dipole results in a radiated power of 1600 watts (1.6 KW). To a listener at the horizon this is equal and identical to the signal received from a 1600 watt transmitter with a single dipole antenna.

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

The advantage to using separate amplifiers is that if you need to service or clean an amplifier you can turn that amplifier off and the other amplifiers stay on and keep the station on air at slightly reduced power. This is an important feature our previous customers like, because the station has significantly less down time for maintenance.

Over the last 12 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.

HOW DOES IT WORK!

19" Rack FM Stereo Exciter with Limiter - This neat, simple and great looking 2U 19" rack unit with intense blue LEDs 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.

19" Rack Amplifier Splitter - The 1 watt signal from the exciter is further amplified by this unit, then it is split accurately in phase and amplitude into separate 1 watt outputs. This important split drives the successive amplifiers and the dipole antennas correctly in phase maximising range to the horizon.

Two 19" Rack 200 Watt Amplifiers - The two amplifiers together produce 400 watts of transmitter power. Each amplifier operates with ease at full power 24 hours a day non stop in any country and with any AC voltage in the world. The amplifiers have a neat little meter on the front panel lit up with intense blue LED's to indicate forward and reflected power. The amplifiers are fully protected from poor SWR and return loss of level for any duration of time.

20 Meter Antenna Cable - This cable is of medium quality and carries the radio signal 20 meters to the antenna, this would normally be used for stations with towers, or masts of 20 meters in height.

4 Way +6dB Stacked Dipole (+7.7dB Gain) - The four way, tier or stacked dipole package includes all four dipoles, phased leads and splitter boxes. The antenna multiplies the power from the antenna cable by 5.8 times horizontally to the horizon making sure maximum signal is efficiently put in the right place and not wasted into space or ground.


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 four stacked antennas on and a standard line level stereo audio feed from your studio mixer or link.

Our final word, at Aareff / Veronica we are primarily engineers with a passion for radio, not sales people. If you have any technical questions please feel free to email us. Geolocation by geoPlugin
