Our regular EFHW antenna has been upgraded with a ultra-durable polycarbonate carbon fiber 3D printed enclosure, customized with your personal call sign on the top cover. This high-performance carbon fiber-reinforced polycarbonate filament is excellent for structural components needing high heat tolerance, stiffness, excellent surface quality, and dimensional stability. Polycarbonate has a Tg (Glass Transition Temp) of 300°F and offers some of the highest thermal performance of any 3d printable material. PC CF is considered among the strongest engineering material you can buy. Our regular enclosures are standard ABS, which is a great, but can crack or shatter if dropped or sharply impacted. It is also not the greatest material for permanent outdoor use. You will never have to baby, handle gently, or be concerned about UV exposure, weather or moisture with this custom enclosure.

I have always believed that if you can put up a dipole you should. I still believe that, but recently I experienced a set of circumstances that would not allow for a dipole. One solution was the well-known EFHW but with some features and incorporate our style and construction techniques. This No Tune End Fed antenna comes complete and ready to use, no kits or assembly are needed. The only option the operator needs to add, if necessary or preferred, is a counterpoise. There is a plethora of information on End Fed Counterpoises and alternative deployment configurations available including AA5TB's phenomenal page: http://www.aa5tb.com/efha.html
The EFHW, or "End Fed Half Wave", is, like all antennas, a compromise. The compromise here is that the antenna is extremely lightweight retailer, adaptable, easy to erect and very, very stealthy but these characteristics are paid for with its efficiency and radiation properties. Nevertheless, it can be a very effective antenna system for SOTA, POTA, Field Day, or Trail-Ready Antenna. The antenna is extremely discreet so it can be appropriate for many HOA installations. Simply raise the far end of the antenna as high as possible, connect the ground or counterpoise and connect your coax and run it as a sloper, this is how I use it. Other configurations can be used including Inverted Ls, Vertical, long angle Zig Zags, "V"s and rhombic.
Designed for portable use, but perfectly workable as a low power base station antenna, the matching unit is a 49:1 Fair-Rite FT140-43 Toroid with bifilar winding as shown in the schematic above, set into a weatherized Polycarbonate Carbon Fiber Flanged plastic enclosure. The wire used is 18 AWG UL 1007 stranded wire which makes this antenna light, portable, flexible and easy to setup. The integrated element is approximately 65 feet long, nearing a half-wave on 40 Meters. This allows operation on that band, plus 20 Meters, 15 Meters and 10 Meters without the use of a tuner. The EFHW is somewhat directional, with radiation mostly running in-line with the antenna. I use mine up in a sloper configuration with the apex in the west and base and ground spike in the east and the results with 10 to 15 watts can be seen in the screenshots above. With this model added to my repertoire, I don't have to erect a dipole or worry about using a tuner if it is impractical or inconvenient.
The antenna comes with a braided copper grounding strap and spike that allows for grounding in the event a counterpoise is not used. Mounting points for ground wires are stainless steel and will not rust or corrode. The antenna collapses as shown, comes in a 9 x 7 camouflage travel bag and weighs a total of approximately 14 ounces.
