Multi Band-Wide Coverage: The uniquely designed OmniX is tuned to multiple bands, giving it wide frequency coverage. Unlike antennas that were originally designed for the ham bands and then marketed as a scanner antenna, the OmniX was specifically designed for scanner radio use and tuned to popular commercial and civil service bands. Elements are specifically tuned for 118-137 MHz, 148-175 MHz and 225-900 MHz, but other bands can be received as well. This antenna can be quite esthetically pleasing compared to discones and it's also more efficient.
DC Grounded: A metal ground plane is not needed with this design.
Solid Construction: The antenna is constructed of 1 1/2" aluminum tube for the core element and solid 1/4" aluminum round is used for side elements. No flimsy tubing or dimple rivets are used. All aluminum is given a brushed finish.
Isolated Mast: The actual vertical structure is comprised of UV resistant plastic. This allows the actual elements to be raised into 'free space', away from your metal mounting mast.
Weather Resistant: All fasteners are stainless steel and the feed point is protected by shrink tube.
High Quality N Connector: Instead of the usual UHF connector that's included with most antennas, this antenna includes a 50 ohm female N connector, on the end of a small cable pigtail. N connectors are more water resistant and handle high frequencies better. Need help choosing your main cable? Checkout the Coax FAQ
Includes Mounting Hardware: Price includes mounting clamps to allow attaching the antenna to any standard 1 1/4" mounting mast.
Only Partial Assembly Required: The core antenna is completely assembled, along with the feeder cable. The only things that need to be done yourself are attaching the side elements, and putting up a mast.
