Since last year, I’ve become a bit of an arborist throw line evangelist. Arborist throw lines have made my wire antenna deployments so quick and easy compared with using monofilament fishing line or more complicated systems.
Since purchasing this arborist throw line last year, I’ve never looked back. The throw line never gets caught in tree branches, it’s reusable hundreds of times, and with it I can easily snag branches 50’+ above the ground to hang my wire antennas.
On this page, I want to share and document my experiences flying and using a kite antenna. There's nothing too special about a kite antenna. It's a fun, novel approach to the ham's age-old question about where to hang a wire antenna. When I lived inland, I could usually find a tall tree in which to hang an antenna. After relocating to the Galvston Island, tall trees are hard to come by. While the beach may lack trees, it usually does not lack wind.
A kite antenna setup is pretty straight forward and once you deploy it a couple times, it's downright simple. The key factor is having enough wind!
Neugierig wurde ich durch eine Veröffentlichung von W9SCH in der SPRAT Nr.69 unter 'A Four-Band UP & OUTER Antenna' und später durch einen Artikel im QRP-Report. Die Antenne ist als 'Upper & Outer' bekannt geworden. Sie besteht lediglich aus einem vertikale Strahler, dünner Draht, der locker um einen Glasfiebermast gewickelt wird und einem horizontalen 'elevated' Radial. Dieses Radial, als 'zweiter Strahler' bildet das einzige Gegengewicht, keine weitere Erdung. 'Wenn Strahler und Radial die gleiche Länge, λ/4 haben, funktioniert die Antenne schon recht brauchbar. Ein Tuner sollte aber eingeschleift werden, um das SWR zu optimieren.
Amateur radio (Ham radio) operators and engineers, have been experimenting with radio and antennas since Marconi. The use of a kite to support an antenna makes for great days operating and a wonderful HF antenna.
The linked pages that are listed below describe
various elements of a typical kite-antenna flying
field setup. One important lesson that we have
learned so far is that good kite-antenna contacts
result from flying the best possible antennas.
Another lesson learned is to keep the time that is
required to set up and put away as short and
convenient as possible - otherwise we will not do it!
Admittedly, we already have a page about our kite antenna exploits which makes for interesting reading. However those pages are about the practical use of these antennas. This talk given by Henryk M0HTB covers some of the background and the equipment considerations to supplement the practical exploits.
Call it the End-Fedz Trail Friendly killer if you like. This thing is much smaller and lighter, and a perfect match for the Mountain Topper series radios when you build in some traps or links.

KW- Vertikal- Antenne für den portablen Betreib
für 7,0 bis 55,0 MHz (6m - 40m)
und ca. 100 Watt HF
Die super Lösung, für den portablen Einsatz.
Leicht im Rucksack zu verstauen.
Ausgefahren mit einer Gesamtlänge von bis zu 5,5m.
Lieferumfang:
● Teleskop- Antenne / Edelstahl- Stab (ca. 5,3m)
● High-Q Luftspule mit Abgriffs- Möglichkeiten
● MFJ-342T Montagewinkel mit PL- Buchse (SO-239)
● das "Gegengewicht" aus vier Cu-Litzen-Kabel (á 3,6m lang) als Radials
Frequency range: 7/14/21/28/50/144/430MHz, Max Pwr input: HF/50MHz: 100W (SSB/CW), 50W (AM/FM), 144/430MHz: 50W (All mode) Height Max 2.2m, 0.6m for transporting * Weight: 930g. Supplied with radiating elements, radial elements for VHF/UHF, radial wires + spare radial wire, Allen key.
The ATAS-25 utilises a manual tuning system which resonates the radiating element for lowest SWR without the need for expensive mono-band resonating whip assemblies. It allows dual frequency operation on HF or 50MHz and either 2m or 70cm (duplexer not supplied). A very handy feature is that the ATAS-25 is designed to mount directly onto a standard camera tripod mount (not supplied) and makes up a portable antenna system ideal for tempory field operation but not recommended for long-term outdoor installation.
For some models, you may wish to purchase a diplexer or triplexer to avoid moving your cable from one antenna jack to another. When using the ATAS-25 with the FT-817, set Menu #07 to REAR for all bands.
Complete antenna system mounts on window frames, balconies, and railings. Perfect for apartment dwellers. Covers 80-6 Meters. Includes universal mount/clamp, built-in antenna tuner with RF isolator, long 12 foot telescopic whip (22.5 inches collapsed), high efficiency loading coil for 40/80 Meters, counterpoise wires, and safety rope. Handles 200 Watts.
