¡¾'King Size' Fiberglass telescopic pole (18m / 60ft)¡¿  Especially developed for successful portable low-band activities on 80 and 160m! Imagine building a quick portable 80m 4-square array that you can put up within less than one hour... Spiderbeam 18m (60ft) fiberglass poles are built very similar to our well proven 12m HD fiberglass poles, yet carefully designed to maintain low weight and perfect balance. The pole starts out very rugged at the bottom (73mm diameter / 2mm wall thickness) and still has 40mm diameter / 1.5mm wall thickness at 10m height! The upper sections are slim and light (1mm wall thickness), preventing the pole from becoming top-heavy and keeping it perfectly balanced. A special reinforcing winding technique - several layers of fiberglass are wound in alternating direction (criss/cross winding) - provides greatly increased lateral and linear strength These poles are perfect for building all kinds of wire antennas, especially 80/160m wire GP or inverted L antennas. They can also easily support temporary lightweight 1 Element Quad or Delta loops for 40-10m, and dipoles for all bands, especially when used with open wire feedline. (Most baluns would be somewhat heavy). 4-6 poles could be used to build lightweight beams for 40 or 80m (...who is going to build one for 160? :-)). The best (and cheapest) wire to use for building such wire antennas (verticals, loops, dipoles etc.) is AWG 18 (= 1mm diameter) enameled copper wire or similar. Pole installation: One person can easily "walk up" the pole by pressing the bottom against a rock, tree, car or ground anchor, or having a second person hold it. Once the pole is in vertical position, it can easily be moved around. Fix the bottom to a ground anchor and attach guy lines at 2 levels. Thin fishing monofilament (1mm diameter) or 2mm Kevlar rope is very suitable for guy lines. To complete the installation we strongly recommend using our rubber padded stainless steel clamps to safely secure the telescoping elements from slipping down. For a pole of this large size, clamps are a better solution than using tape only. SET PRICE: EACH POLE INCLUDES A FREE STAINLESS STEEL CLAMP SET! Get your 18m pole today and enjoy successfully putting out a big low-band signal within just a few minutes... ¡¾MFJ-1910 33 foot Telescoping Fibreglass Mast¡¿  The MFJ-1910 Telescoping Fiberglass Mast is 33 feet tall, yet collapses to a mere 3.8 feet and weighs only 3.3 pounds! You simply pull out each section and twist to lock. It extends to a whopping 33 feet -- a full quarter wave on 40 meters! The bottom section is 1 3/4 inches in diameter. It's great for portable and temporary use -- traveling, camping, from hotels, hamfests, field day, DX-peditions. Put up a full size inverted Vee dipole or full size vertical antenna in minutes and get full size performance! You can Use to make other antenna like loops and quads! The Telescoping Fiberglass Mast is made of super strong fiberglass flexes to resist breaking. Its black coating resists UV. ¡¾MFJ-1910 33 Feet Telescoping Fiberglass Mast Instruction Sheet¡¿  Thank you for purchasing the MFJ-1910 33 Feet Telescoping Fiberglass Mast. Please read these instructions carefully before use. Caution! Improper extending and collapsing of the MFJ-1910 mast can cause the sections to bind. DO NOT collapse the top section (thinnest section) first. If the top section is collapsed first, it can get lodged between the larger sections. This will cause the sections to bind and you will not be able to fully collapse the mast. You may not be able to fully extend the mast the next time you use it. To avoid this, follow the directions below. When extending the mast, be sure the thin, top section with the metal loop is extended first. After extending the top section, twist the section at the joint slightly for a tighter fit. Then proceed to the next section. Follow this procedure until the last section is tightly in place. When collapsing the mast, begin with the bottom section. Twist the sections at the joint to loosen and gently lower into the bottom section. Then proceed to the next section. The last section lowered into the base should be the thin, top section with the metal loop. If sections of the MFJ-1910 mast become wedged together unscrew the cap on the bottom of the mast. All sections should be removed from the bottom until the sections wedged together can be seen. Remove the top section from the sections stuck together. Replace the sections (largest diameter first). Screw the bottom cap back on after replacing the last section. ¡¾Spiderbeam 18m fiberglass pole¡¿ Especially developed for successful portable low-band activities on 80 and 160m!
