2M9X Description     Hide

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” series 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 antennas are that they are more portable with the smaller sections. The 2M9X replaces our very popular 2M9SSB/FM.

Each models performance is optimized for a specific mode and frequency range, with no compromises to achieve unneeded bandwidth. The 2M9XSSB covers 144-146 MHz and the 2M9X FM covers 145-148 MHz. Where do you want to make yourself heard?Both models are ideal building blocks for a small turning radius, high-gain stacked array. Two horizontally polarized, vertically stacked 2M9X’s yield the same gain (14.8 dBd) as M2’s 33 ft 2M5WL, but with about 1/2 the turning radius. Great for QTH’s that won’t permit a long boom Yagi. The 2M9X can be stacked on a crossboom for the same gain increases, and the turning radius is still a very manageable 10 ft.

The heart of these antennas is a driven element module originally designed for maritime ATS satellite service. All connectors are O-ring sealed to the CNC machined block. Internal connections are sealed with a space-age silicone gel with nearly 4 times the dielectric strength of air. The balun connectors are triple sealed on the coax and nut-sealed at the block connectors. The type “N” feed connector uses a gold-plated, beryllium copper center pin.

Elements are 6061-T6 3/16” solid rod with UV stabilized polyethylene Button insulators and stainless steel keepers. Thousands of these type elements are in amateur and commercial service with NO failures! Booms are constructed of 6061-T6 aluminum alloy tubing. Other key electrical and mechanical components are CNC machined for accuracy and durability. All hardware is stainless steel except the U-bolts. For uncompromising performance and long term electrical / mechanical integrity, the 2M9X is unmatched.
