Choose the best transmitter for your LPFM station.

As a smaller broadcaster, usually on a tight budget, making the wrong decision about what transmitter to buy could mean your LPFM station fails before it’s even got off the ground.

Aqua Broadcast is at the forefront of designing and manufacturing FM transmitters for broadcasters worldwide who are regularly choosing Aqua Broadcast for their FM Transmitters.

We have your back!

Whether you are starting a new LPFM in the application filing window in November 2023, or looking to update your older LPFM Transmitter, don’t make the wrong decision about what transmitter to buy, Aqua Broadcast can help you.

Confidence

You can only use a transmitter that is certified for LPFM use which has an “FCC ID” label on the transmitter. If it does not have the FCC ID label on it, it can’t be used for LPFM. All Aqua Broadcast COBALT FM transmitters from 10W to 1000W have an FCC ID, they were all tested and verified by an FCC approved Lab and certified for use.

Why do I need 300 watts for a 100 watt licensed LPFM station?

If you want to broadcast the best signal possible for your listeners (greater coverage) you’ll probably want to use a circular polarized antenna to enable you to broadcast in both horizontal and vertical planes. Without getting too technical, this helps listeners receive your broadcast better no matter where they are, including in their cars and homes. You can’t always control which way your listeners position their antennas so it’s always best to pick the right antenna to maximise performance for ALL your listeners.

When you want to connect an FM transmitter to a circular polarised, you’ll need to provide the antenna with double the RF power to get the same power broadcasted horizontally and vertically. The cables that connect the transmitter to the antenna will have losses (lose you RF power), so if you are serious about how well your signal broadcasts, and you really want to run at your full licensed power, you’ll need to be looking at a transmitter that can deliver at least 250 watts - no problem with the COBALT C-300 from Aqua Broadcast.
