ratio balun. Bill claimed that the antenna is usable on most bands without a tuner (SWR <2:1) by adding a 1/4 λ wave transmission line impedance transformer cut for 15m and changing the balun ratio to 1:1. T h ei ncov f tsw d balu overcome if the feeder end and balun are brought into the shack. Using a tuner the antenna also works on 30, 17 &12m. ZS6BKW Optimized G5RV This antenna uses high quality: - #14 7 Strand Hard Drawn Bare Copper Wire - WA1FFL Ladder Line LOC Center Insulator - #18 450 Ohm Steel Copperclad Ladder Line ZS6BKW G5RV with the added benefit of 1:1 balun

- The RBA-1:1 Balun Current Balun was designed to allow easy interface of ladder line antennas and long wires to the LDG line of Automatic Antenna The Balun operates "stand alone", thus does not require an LDG Tuner. It may be used with any of your long, random, or ladder line antenna projects. |

- Brian Austin ZS6BKW/G0GSF searched for combinations of antenna length and feedline length which would provide a reasonable match to 50 ohms on a number of HF bands; he was successful - he found that an antenna 93ft long fed with 39.8ft of 400 ohm ladderline (Vf=0.9) provides a reasonable match on five bands. |

Back to the ZS6BKW… two years ago I constructed a ZS6BKW antenna using Dx-Wire and lightweight 300 ohm twin-lead feedline and promptly placed it in my storage box of portable HF antennas. Balun Assembly. Inside the Jiffy box. Foam packing to prevent vibration and damage to the ferrite cores.Marc, N4UFP, and I get together to talk about, build and test the ZS6BKW antenna. This is a much MUCH better performer than the heavily marketed G5RV! If you're only going to have one antenna, this is THE ONE to have. Easily built with readily available parts.
A balun's purpose is to allow connecting a balanced, (e.g., a dipole or driven element) to an unbalanced line such as coax which is not balanced, thus the The 1:1 choke "balun" is not actually a balun. It's function is to help eliminate rf currents from flowing on the outside of coaxial cable using the principle...für alle Baluns mit einem von 1:1 abweichenden Übersetzungsverhältnis! Wenn dagegen echte Langdrähte gespeist werden, Stromsummenantennen, Ganzwellenschleifen, dann kann man das verantworten . Ein ordnungsgemäß aufgebauter Balun verhindert, dass Gleichtaktströme fließen und es dadurch zu Störungen beim Senden und Empfangen kommt.
*Includes 11 inches for balun. The 80-meter broadband antenna system. Fig 1 shows the simple broadband antenna system as used at my station. The antenna proper is a center-fed half-wavelength dipole. The transmission line is segmented into one electrical wavelength of 50Ω coax and an electrical quarter wavelength of 75Ω coax. Balun Designs Baluns now available for $85 each. NEW! 100 foot roll of 3/32" Dacron Line for $9.00 each. For more information, see the Frequently Asked Questions (FAQ) Page. Or, if you are ready to purchase, see the How To Order page.

An Updated Version of the ZS6BKW Multiband Dipole - Wireless Waffle is a UK based blog covering amateur radio, broadcasting, terrestrial and satellite, licensed and unlicensed, spectrum management and more. Feb 21, 2010 · In the mid-1980s, Brian Austin (ZS6BKW) ran computer analysis to develop an antenna System that, for the maximum number of HF bands possible, would permit a low Standing Wave Ratio (SWR) without antenna tuner to interface with a 50-Ohm coaxial cable as the main feed line.

So, it's a cousin to the G5RV (which only resonates on 14 & 24 MHz), but better as it needs no ATU on 40, 20, 17, 12, 10 Kevin VK2FUO advises to put a 1 to 1 current balun on the ZS6BKW antenna 450 ohm feeder line where it joins the 50 ohm coax to the radio.
- Homemade dillon 550b toolhead standsince 1958. Professor Brian Austin ZS6BKW remodelled and revised the dimensions of the antenna with improved results and ease of construction.
