The SQBM4010P Quadband 10/4/2/70cm Base Antenna is a versatile vertical antenna that covers four bands with a single feed. Constructed from durable fibreglass, this antenna boasts a frequency range of 29-30/70-71/144-146/430-440MHz. With gains ranging from 2.5 to 5.5dBi, it offers reliable performance. Measuring a length of 1.2m, it is equipped with a SO239 connection and can handle up to 50 Watts of power. Despite its compact design, users should know that VSWR on specific frequencies may exceed 2:1 due to its size limitations.

Included with the SQBM4010P antenna is all the necessary mounting hardware for easy installation. Featuring three X87cm radials, this antenna ensures stability and efficient signal transmission. It is designed to perform optimally on the 144-146/430-440MHz bands, with a VSWR of 1.5:1 or better. Users should consider that while this antenna offers convenience by covering multiple bands, its compact size of 120cm means it may not deliver the same level of performance across all frequencies.

In conclusion, the SQBM4010P Quadband 10/4/2/70cm Base Antenna is a practical solution for operating on multiple bands with a single antenna. Its compact and durable design, specified frequency range, and power handling capacity make it a suitable choice for many amateur radio enthusiasts. However, users should be mindful of its size limitations and potential VSWR issues on specific frequencies when considering this antenna for their setup.
