The Pro-Tube 30" Powder Coated Steel Antenna Mast is a 30-inch long, 18-gauge, heavy duty, powder coated galvanized steel antenna mast.  This mast is designed for commercial and residential mounting of TV antennas, wifi antennas, cellular antennas, weather stations, and more.  The Pro-Tube 30" Powder Coated Steel Antenna Mast is constructed of 18 gauge high-tensile steel tubing that is galvanized inside and out for maximum weather protection and rust prevention.  Most other antenna masts have a raw metal finish, giving an unprofessional and unfinished look to an installation. The Pro-Tube textured gray powder coat not only provides an additional layer of protection but also an elegant, finished look for high visibility installations and for higher-end commercial and residential properties.  (This mast is most commonly purchased with the Pro-Mount and Pro-Model Antenna)
