The OB8-4M is an extremely effective, compact and innovative Yagi for the classical four bands 40, 20, 15 and 10m. It is the first trapless Yagi for this frequency spectrum in the world with a single 50 Ohm coaxial feed and with two powerful Moxon Rectangles integrated in its design to improve performance. A mechanically brilliant power house without compromise, the next level of antenna performance!
The Par SM-50 occupies approximately 1/2 the footprint of a traditional 2 element yagi, yet features nearly identical electrical specifications. The radiator material selection results in a further reduction in size and weight over classical Moxons. Once the matchbox is installed onto the main radiator (two 10-32 screws), assembling the rest of the antenna including mast mounting and tuning, requires no tools.
