FM transmitter 5w

Specifications

Features:

This unit includes all the components and circuit boards fully tested and assembled inside a box. Other items include a 12 volt, 2/5A SMPS power supply with DC pin,(8GB SD card with songs card only in 5-watt version), BNC connector, antenna key items & audio cable.

The  5  W FM transmitter has a control panel with a dot matrix LCD display screen and  3 key buttons to change frequency, volume, and range by changing the output transmitting power.
Control panel: 58 x 36 mm (as shown in the picture)

The range/distance: 5 watts with Yagi antenna good directional coverage with Yagi antenna is about 12 KMs, with dipole about 7 KMs (Guaranteed if our dipole is used), with GP antenna only 3KMs  .(when a premise is in open field emission) Homemade Yagi antenna as per sample Yagi antenna design only is given to fabricate at home. Please note any antenna is optional at extra cost.
Transmitter  key features:
1, Digital technology, makes the frequency more stable, the frequency does not change with the environment and produces frequency drift.
No need for any adjustment inside.
2, But the frequency can be adjusted digitally by buttons within the specified scope.
3, The 5 watt has a micro sd socket to use any 8GB or more card  (Card supplied at extra cost) holding 1000’s of old MP3 Bollywood cinema songs and one can add more than 6000 songs from any computer through the SD card adapter supplied.No need to use any external audio feed into the aux socket.—

4, Also with the microphone input interface. With 2 mics stereo transmission can be done. All through the digital potentiometer, it is easy to control the volume of the microphone (supplied at extra optional).
5, Audio input ay aux also by a digital potentiometer to adjust the volume.
6, Transmitting Power can be changed between 0.5 W and 5 W maximum having continuous adjustments features to adjust the range from 100 meters onwards to KMs.
7, The power output network for harmonic suppression is very good, so as to make the output spectrum cleaner.
8, Set the frequency and power once and the next time boot does not need to do the set up again!

Main parameters:
1, The input voltage: dc 12 v
2, Maximum input current 1.5  A at 12 v DC
3, The audio signal: the maximum input Vpp is less than 1 v.
4, Microphone types accepted: Any, condenser microphone.
5, The output power: 0.5 W – 5 W continuously adjustable!
6, The output impedance: 50 Ω for antenna
7, Working frequency range: 76 m – 108 MHZ
8, Frequency step of 0.1 MHz for adjusting
9, The distortion degree: 0.03% ~ 0.1%

FAQ:–

How far (long) the transmitter will cover?

The transmission range depends on many factors. The true distance is based on the antenna installing height, antenna gain, using environment-facing buildings and other obstructions, the sensitivity of the receiver, and the antenna of the receiver. Installing the antenna at a higher height and using it away from cities, the distance will be much longer.

EXAMPLE:- 5 W FM Transmitter used in the city and village with GP  vs  Dipole Yagi antenna:

I have many customers in India who use our this 7 FM stereo transmitter with a home-built GP antenna they have tested it with a car FM radio (not cell phone FM radio) and, it covers a good range in a city area with clear sound and no hissing noise.  The distance can be high while using a homemade directional Yagi antenna or buying a dipole antenna.

Most Important
Antenna either Yagi, dipole, or GP (ground plane) must be used in this transmitter with 50 ohms coaxial cable RG58( Or the type used by cable tv operators). The cable is to be procured at your end. GP / Dipole antenna is available at extra cost
