Our best-selling 21' telescopic mast is made of the highest quality anodized aluminum and built to last. Extremely portable but ready to provide years of permanent service too!

Weighs just 4.6 lbs for easy carrying and perfect for temporarily supporting antennas. More versatile than fiberglass or plastic masts and particularly useful when a lightweight metal mast is required. Five non-tapering sections expand from just 63 inches to a full 21 feet. Bottom section is 1.5" in diameter. The top section is 1" in diameter and perfect for mounting most any small to mid-size antenna or weather system. Tube wall thickness is 1/16" and four heavy-duty thumb nut compression clamps make for quick and easy adjustment of individual sections.

You can raise any section by any amount to get the exact height and rigidness you need! When securely mounted at the base and with most lightweight items attached, guying is not usually necessary. However, guying is always recommended.

The most frequent question we are asked is "How much weight will this mast support?" The answer is... It will depend entirely on what you mount on it, how it is mounted at the base, if guys are used and how you plan to extend the mast with the load attached. Our own personal, unscientific experience has shown 5 to 10 pounds of vertical weight is reasonable. Keep in mind, this is vertical weight and wind and/or off-center mountings may cause the mast to sway or flex. Once again, guying and a good base support is highly recommended.

Used in conjunction with our matching mounting brackets (PENNPMBS-1500), this mast is IDEAL for permanent mounting on RV's, buildings or posts! The ability to raise and lower it quickly means this mast can stay mounted all the time. For portable applications, we have matching tripod (PENNTB-1500) and drive-on tire mount (PENNTMT-1) options available too. See our other listings for more info on these items!
