The ShengDa Com SDN3VU Logging Road Commercial Dual NMO Mobile Antenna is a high-quality radio antenna designed for amateur radio enthusiasts who require a versatile and efficient antenna for their mobile applications. The SDN3VU model is designed to be mounted on a vehicle or fixed location using an NMO mount and features a broadband design that allows it to operate on a wide range of frequencies.
The SDN3VU antenna is a dual-band antenna, which means that it is capable of transmitting and receiving signals on two different frequency bands: VHF and UHF. The VHF frequency range is 150-155 MHz, while the UHF frequency range is 450-470 MHz. Additionally, the antenna features a land mobile design that allows it to transmit on the commercial frequency range, making it ideal for use with frequencies outside of the amateur band, for example logging roads.
The SDN3VU antenna is constructed using high-quality materials to ensure durability and reliability. The antenna is made of stainless steel, which is resistant to rust and corrosion, and the base is made of high-strength magnet materials. The antenna is also designed to be weather-resistant, so it can be used in all kinds of weather conditions.
This antenna has a total length of ~890 CM, and it has a unity gain of 2.5 dBi on the VHF band and 3.5 dBi on the UHF band. The antenna also has a power rating of 100 watts, which means that it can handle high power transmissions without being damaged.
One of the best features of the SDN3VU antenna is its optimization for the land mobile frequencues. This allows the antenna to operate efficiently on the logging roads and other frequencies commonly used on the highways. The antenna is also designed to be easy to install, thanks to the NMO mount.
Overall, the ShengDa Com SDN3VU Broadband Dual Band NMO Mobile Antenna is an excellent choice for amateur radio enthusiasts who require a versatile and efficient antenna for their mobile applications. Its dual-band capability, broadband design, durable construction, and easy installation process make it a great choice for a wide range of radio applications.
