In addition to enhanced performance and reliability, the CM-3000HD was also designed with the consumer in mind with an aesthetically pleasing design, not to mention it comes with both a simple table top stand for indoors and a very versatile mounting bracket for easy outdoor mounting. Just like it's predecessor, the SMARTenna still boasts an omnidirectional design allowing for reliable signal from multiple directions without the need of rotation. The SMARTenna is a SMART choice for anyone that is relatively close to the broadcasters and needs a quick and easy solution to receive FREE HDTV channels from all directions.
