Made in the USA!
This 2 section 16 gauge inner, 18 gauge outer, Telescopic Antenna Mast collapses down to 10 Feet in length that with overlapping, extended mast height is 19'-3", Used for Mounting Off-Air TV, Ham Radio, MMDS and Wireless Internet Antennas.
Manufacturers recommend that mast heights of 10 feet and higher above the uppermost bracket be guyed for Addition Wind Load Support. Bonding/Grounding should be made by affixment to Mast. Consult NEC and Applicable Local Code for further guidance
(Antenna, Down Guys and Mounts not included).
19'-3" extended Height
This Item Ships LTL Freight ONLY.
Mast Section Dimensions are:
(1) 10'0" length x 1.25" O.D. (16 AWG)
(2) 9'10" length x 1.50" O.D. (18 AWG)
We Stock the Highest Quality Telescopic Antenna Masts made from 18 and 16 AWG galvanized steel right here in the USA. These Masts are suitable for tons of applications where a fast an simple extension is needed. They have been used for everything from digital TV antenna applications to wireless communications to weather stations and even IoT Sensors. The masts can be used retracted or fully extended and anywhere in between. They can be supported and mounted against a structure, mounted on a roof or even guyed in the middle of a field. Our reliable and durable telescopic poles come in heights of 20, 30, 35, 40 and 50 FT and all have a engineered thumbscrew/collar system for setting height.
Manufacturers recommend that mast heights of 10 feet and higher above the uppermost bracket, mount and/or preceding guy level be guyed at the uppermost level for Additional Wind Load Support. Bonding/Grounding should be made by affixment to Mast. Consult NEC and Applicable Local Code for further guidance.

Assembly (2 Man Team min., no Wind)
Erection is made by simply connecting guys and brackets to the attached unique heavy duty rolled edge guy rings and clamps, extend each section one at a time (starting with the innermost section), insert the locking cotter pins, rotating the tubes to a locked position, and tightening the clamps. Repeat the process on each successive section until fully erect.
1. Pre-install Mast Base with its Anchor Pin embedded into a small concrete Pad (mindful of frost layer depth) that extends its height above surrounding Grade Level (finished surface should have an ever so slight Crown as to prevent Water Pooling.
Install the Down Guy Earth Anchors into firm soil, clay or embedded concrete with a depth that allows only a few inches of the anchor rod and the anchor head showing above Grade.
(see the installation Guide/ Spec. Sheet and/or Associated Graphs/Photos for particular Mast Sizes for distances, angles and guy wire lengths)
2. Secure guy wires of the proper length needed to reach the anchors to the Guy Ring at the top of the Bottom Outermost Mast Section, through the appropriate Hole provided on the Guy Ring (holes for 3 and 4 way guys) and then back on the wire itself, terminating said guy wires with 3 Cable Clamps in a Row
3. Mount entire collapsed Telescopic Mast onto Base as provided, and attach the other end of the guy wires you just terminated onto the Down Guy Earth Anchors. Align the mast vertically while tensioning the Guy Wires to maintain plumb under tension.
4. Next, select the Top Innermost Mast Section (1.25" 16 gauge) and Secure its upper Guy Ring using the provided Mast Clamp to the desired location height anywhere along this particular Mast Section upon which it will rest securely under tension(see note 8 on page 10). The Guy Ring on this Mast Section only, can be affixed anywhere along the length of the Mast to leave room for Antenna Structure Attachments, Appurtenances etc., above it. (none of the remaining Mast Sections will have this adjustment Feature)
5. Secure (Terminate with 3 Cable Clamps in a Row) the appropriate length Guy Wires to this previously affixed Guy Ring and let them hang freely out of the way until all sections are raised.
6. Locate the Cotter Pin Holes at the top of the next innermost nested Mast Section and view while raising the previous Mast Section until you see its Bottom pass above the Cotter Pin Holes.
(At this point the Mast Section is extended Completely)
7. Insert a cotter pin passing through the Holes, secure and then lower the raised Section as to Rest upon it.
(There are usually half circle notches at the Mast bottom that will "saddle" the Cotter Pin when lined up)
Assure the Proper Installment of the Cotter Pin, the Mast's Position resting upon it and then tighten the mast clamp.
(the cotter pin remains for security and failsafe)
8. Secure appropriate length guy wires to the next highest Guy Ring of the corresponding Mast Section, and let them hang.
9. Raise the next smallest Mast Tube and insert the cotter pin.
10. Make sure that the cotter pin is inside/below the notch appearing at the bottom in the inside tube.
11. Secure the cotter pin and tighten the mast clamp.
12. Repeat steps 8-10 until all sections have been raised and are secured.
13. Attach all hanging Guy Lines to their respective anchor. Align the mast vertically by tightening the Guy Lines. Make sure to work your way up the mast while tightening.
