M2 2M7X

M2 is always trying to design and build new antennas to fit the needs of amateur radio operators. The “X” series of antennas are all designed to keep the packaging under 48” long to minimize oversize surcharges applied by shippers. The “X” serries antennas offer the same performance as its predecessor, but with shorter boom sections. The boom sections also have a thicker wall for added strength. A side benefit of the “X” series antenna are that they are more portable with the smaller sections. The 2M7X replaces our very popular 2M7.

The 2M7X is a computer optimized Yagi that will outperform longer old design antennas. The 2M7 covers the whole band with only slight performance degradation at the band edges. Side lobes are very low and it is perfect for stacking 2 or more. Its light weight and durability make it great for portable hill topping.

The 2M7X is built for long term electrical and mechanical integrity. The CNC machined “T” Match Block features O-ring sealed connectors and is internally sealed with a space-age silicone gel with nearly 4 times the dielectric strength of air. Elements are 6061-T6 3/16” aluminum rod, mounted through the boom on UV stabilized button insulators. All hardware is stainless steel except U-bolts. Other key electrical and mechanical parts are CNC machined for accuracy and durability
