Why use your limiters? the bigger nice looking 19 inch rack limiters from Behringer and other similar brands are the same price?

For FM broadcasting the attack has to be very fast at all audio frequencies, audio above 15KHz should be cut and pre-emphasis has to be applied before limiting.The commercial 19 inch rack mount type limiters, compressors and audio processors that are for bands, discos and recording studios don’t do this.

Our limiters do not use any digital sampling, they are high quality, low distortion, low noise and analogue design, perfect for FM transmitters.

Our limiters start to cut off sharply at around 14 KHz using a Salem and Key active filter. The commercial 19 inch rack mount type work up to 20KHz and way beyond, in the applications they are designed for this is okay and there’s no reason to cut the frequency above 15 KHz. They are not designed for FM transmitters

A radio repeater is a combination of a radio receiver and a radio transmitter that receives a weak or low-level signal and retransmits it at a higher level or higher power, so that the signal can cover longer distances without degradation.

It is an automatic radio-relay station, usually located on a mountain top, tall building, or radio tower. It allows communication between two or more bases, mobile or portable stations that are unable to communicate directly with each other due to distance or obstructions between them.

The repeater receives on one radio frequency (the “input” frequency), demodulates the signal, and simultaneously re-transmits the information on its “output” frequency.

This can be minimsed to virtually zero by mounting the dipoles in a specific way.

A 30 degree protection zone from lightning strikes can be formed. To do this the mast, tower or pole should be higher than the dipole clamped to it. Using our dipoles the 30 deg protection zone is formed when the distance between the top dipole boom and the top of the mast, tower or pole is a minimum of 2 metres. If this distance is made greater than 2 metres by lowering the top dipole, then even further protection will be formed.

If at all possible it is also a good idea to drive a copper earthing “spike” into the ground by up to a 1 metre if possible. Then bolt this firmly via thick earthing cable with stainless steel or brass screws to the bottom of the mast, tower or pole.

What range can I get?

The power you need depends on the geographical terrain and how high your antenna is mounted.

Radio signals are radiated from the antenna, not the transmitter. Given this, if you mount the antenna higher, the antenna can see further and you will get further range. Another good rule of thumb is that if you increase antenna height by 3 times the antenna will see double the distance, therefore potentially doubling the range if you have enough power.

Does this transmitter already come with the proper antenna that enables it to reach the full range of transmission?

This is the transmitter only, it does not come with any antenna. This transmitter is available in the 250W ERP package, this package includes antenna cables and everything you need to get the transmitter system up and running on delivery. The only thing you need to provide is the pole / mast for the antenna and your studio.

Community radio is a radio service offering a third model of radio broadcasting in addition to commercial and public broadcasting.

In many parts of the world, community radio acts as a vehicle for the community and voluntary sector, civil society, agencies, NGOs and citizens to work in partnership to further community development aims, in addition to broadcasting.

They are generally non-profit and provide a mechanism for enabling individuals. These stations typically are low budget and involve broad participation by community members—often on a volunteer basis
There are stations financed by donations from listeners, by international development agencies, by advertising and by governments.
They are located in isolated rural villages and in the heart of the largest cities in the world.
