--- title: How a CB Radio Antenna Works and Why You Must Select Carefully! description: The Citizen Band is widely known as a “CB” radio. It is basically a radio transceiver for two way communication over a CB radio antenna. The role of the antenna on a CB radio system is dual. First it captures inbound radio-frequency signals, then converts them into electrical signals by the CB’s receiver. Second, it converts outbound electrical signals from the transmitter into radio-frequency signals that are then broadcasted onto the air waves and to another receiving CB radio. This is how the transmission process works. And it is precisely there where proper tuning of the antenna becomes important. image: https://cdn.shopify.com/s/files/1/0345/4055/2323/files/tyy_480x480.png?v=1698955045 --- [Skip to content](https://blog.arcantenna.com/blog/how-a-cb-radio-antenna-works-and-why-you-must-select-carefully#main-content) [![Arcadian](https://blog.arcantenna.com/hs-fs/hubfs/Logos/Arcadian-Logo.png?width=300&height=70&name=Arcadian-Logo.png)](https://www.arcantenna.com/) Open main navigation Close main navigation - [Contact us](https://www.arcantenna.com/pages/contact-us) [Contact us](https://www.arcantenna.com/pages/contact-us) 1.

This is how the transmission process works. And it is precisely there where proper tuning of the **[antenna](https://www.arcantenna.com/collections/search-results?type=product&q=cb+antennas)** becomes important. **Front-Runner CB Radio Antennas for Businesses** [![](https://cdn.shopify.com/s/files/1/0345/4055/2323/files/tyy_480x480.png?v=1698955045)](https://www.arcantenna.com/products/pulse-larsen-nmo27c-low-band-mid-band-omnidirectional-whip-antenna) One of our most requested CB radio antennas is the **[NMO27C](https://www.arcantenna.com/products/pulse-larsen-nmo27c-low-band-mid-band-omnidirectional-whip-antenna) - a high performance NMO CB Radio Antenna**. It has a working frequency of 27-31 MHz. It is highly regarded for its solid structure, high gain, and efficiency among CB antennas. It is a base-coil style antenna. It has a strong stainless steel whip and does not erode or break down over time, compared to more fragile antenna styles. Another great option when shopping for CB radio antennas for is the [**quarter wave CB antenna.**](https://www.arcantenna.com/products/c27-laird)It is unity gain like the one pictured above, and, amazingly, it is only 53 inches long and works like a 102 inch long whip! Talk about efficiency! It is base coil as well. These CB antennas are wonderfully effective for large-scale business operations. The size and build works well. **[This antenna](https://www.arcantenna.com/products/c27-laird)**is highly tunable - between 26.965 - 27.406 MHz and a 10 Meter range.
