250W ERP FM SYSTEM WITH 2 WAY STACKED DIPOLE
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" 100W Stereo Transmitter
- 20 Meter Antenna Cable
- 2 Way Stacked Dipole (+4.8dB Gain)
250 WATTS Effective Radiated Power - The combination of 100 watts transmitter power, 20 meters of foam grade LMR400 and a two way stacked dipole antenna results in a radiated power of 250 watts. To a listener at the horizon this is equal and identical to the signal received from a 250 watts 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.
HOW DOES IT WORK!
Standard System - 19" Rack FM Stereo 100 Watt Transmitter. The standard system uses our 100W FM stereo transmitter. This transmitter is based on our highly efficient 100W amplifier that customers have purchased for many years. It produces 100 watts at full power 24 hours a day non stop in any country and with any AC voltage in the world. On the front panel is a little meter lit up with intense blue LED's to indicate forward and reflected power. The transmitter is fully protected from poor SWR and return loss of level for any duration of time. Finally this transmitter complies with ITU standards, exceeds FCC spec, it is excellent value for money. In fact we would go as far to say that it is the best you will buy on the market for your money.
System with Audio Limiter Compressors - 19" Rack FM Stereo Exciter with Limiter and 19" Rack 100 Watt Amplifier. This neat little combination is the two following 2U units together.
The first unit is a simple and great looking driver exciter 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.The second unit is the 19" Rack 100 Watt Amplifier that produces 100 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 - This cable is high quality foam and carries the radio signal 20 meters to the antenna, this would normally be used for stations with towers, or masts of up to 15 meters in height.
2 Way +3dB Stacked Dipole (+4.8dB Gain) - The two way, tier or stacked dipole package includes two dipoles, phased leads and splitter box. The antenna multiplies 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.
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.
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.
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.
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.
