The Channel Master Attic TV Antenna Mount offers a convenient solution for those aiming to install a TV antenna in their attic space. Easy to set up, it accommodates most mast-mounted antennas available on the market. The included 18” mast suits all Channel Master antennas and pairs well with our Omni antenna (sold separately) for attic installations. Ideal for individuals seeking to mount an outdoor TV antenna in their attic for aesthetic purposes or to comply with homeowners association regulations, the Attic TV Antenna Mount is compatible with most outdoor TV antennas. Constructed of solid steel, the mounting bracket is designed for attachment to a flat surface like a standard rafter or truss in an attic. The included 18” mast clamps onto the mounting bracket using the provided nest and u-bolt assembly, facilitating the mounting of any antenna designed to clamp onto a pole up to 1.5” in diameter. Please note: Installing a TV antenna in an attic can be challenging and may not be recommended in certain scenarios. While attic placement allows for a higher mounting point, factors like obstructions and potential interference from construction or electrical/HVAC equipment must be considered. While this isn't meant to discourage attic installations, it's important to be aware of potential challenges. Whenever feasible, we recommend outdoor mounting at or above your roofline and directed towards transmission towers for optimal signal reception.
