Outdoor antennas usually require a mount and mast (pipe).

Mounting Options:  
• Tripod mount
   - used on rooftop at peak
   - good for large antennas
   - good for use with a rotor
• Wall mount
   - used on side of house
   - available in 4 ~ 18-inch standoffs
   - heavy duty models for larger antennas
• Eve mount
   - used on end (gable) of house at peak
   - combines wall mount with eve bracket
• Chimney mount
   - chimney must be structurally sound
   - can damage chimney if overloaded
   - pair of straps wrap around chimney
• Roof / Attic mount
   - OK for small antennas
   - use with guy wires for larger antenna
   - essentially an adjustable bracket
• J-mount
   - include bracket & mast
   - OK for small antennas only
   - fasteners are sometimes included
• Universal mount
   - similar to J-mount above
   - include bracket & mast
   - OK for small antennas only
   - fasteners are sometimes included

Common Mast Options:  
• Channel Master Antenna Mast Sections
   - 5-foot long or 10-foot long
   - 1.25" OD (outside diameter) x .049" thick
   - 18 gauge galvanized steel
   - swaged end facilitates stacking together

EMT (electrical metal tubing) in 10-foot lengths
   - trade size of 1" = 1.163" OD x .057" thick
   - trade size of 1.25" = 1.51" OD x .065" thick
   - trade size of 1.5" = 1.74" OD x .065" thick
   - galvanized steel
   - available locally at Home Depot & Lowes

All antenna masts taller than 10 feet should be installed with guy wires for maximum stability and safety.

You can use these Channel Master instructions as a guide to where and how to install an antenna.

If you have a directional antenna and want to pull in weak stations from opposite directions, you can use a rotor to turn the antenna towards the broadcast tower of choice.

WARNING: Do NOT mount any antenna in close proximity to or above any power line. If the mount or antenna or cable should fail, no part of the antenna, mount, or cable should be able to contact a power line.

WARNING: Your antenna (sometimes with a fastener on the mast) and feed line MUST be grounded. Your antenna may have instructions for grounding; if so, be sure to follow them. Use a suitable ground wire (or coax feed line that includes a suitable ground wire) to connect the antenna and/or mast to a suitable ground as defined by National Electric Code (NEC). No splices or connections are allowed in the ground wire between the mast and the ground. You should also ground the coax feed line with a grounding block which is also connected to a suitable ground. Grounding MUST be done per the NEC AND any additional local codes in your town. Some towns may also require a building permit and inspection.
