I find that tool particularly useful because it has wide applicability but it is neither easy to use. Where practical Yagi antennas become a bit out of reach for most hams. Blue plot is the phased design black the three element refl ectordirector and red a two element Yagi.

Long yagis are commonly used from the 144MHz amateur band to the 24GHz band. Anything is scaled to 11m from the 10-Meter ARRL project. Antenna Book and ARRL electronics data book.

Lawson might be helpful. The ARRL-Antenna Compendium Volume 3 Editor Gerald L. Selecting the best VHF or UHF antenna for a given installation involves much more than scanning gain figures and prices in a manufacturers catalog.

This article below was written by WA7RAI and will serve to introduce you to a computer program for designing Yagi antennas that you can download. I routinely use HFSS at work and own a personal seat for occasional consulting. The design program is best suited for antennas in the VHF UHF and Microwave frequencies because lower frequency antennas that have gains between 118 to 216 dBd tend to be physically impractical.

Wide-band Yagi designs for 10 meters at 285 MHz. Yagi Uda Antenna Designer NBS Tech. It is in ZIP form and you must unzip the downloaded file to a folder of your choice.

Lower frequency antennas that have these attributes tend to be physically impractical. Yagi Calculator is a Windows program that also runs well on Linux Ubuntu 810 under Wine to produce dimensions for a DL6WU style long Yagi antenna. In my case the antenna was completely made from discarded Yagi beam elements a junk box vertical.

Jerry Hall K1TD. According to Yagi Analyzer the simple program that comes with The ARRL Antenna Book3 the antenna has 106 dBi of free-space gain with the unwanted lobes suppressed by 20 dB–a reasonably clean pattern. VHFUHF Yagi Antenna Considerations – ARRL Antenna Book 20th Edition.

Blue plot is the phased design black the three element refl ectordirector and red a two element Yagi. Yagi Antenna Design This site offers a free interactive design page to let hams design Yagi antennas for HF VHF and UHF.

This chapter by Chuck Hutchinson K8CH covers theory and construction of antennas for most radio amateurs. HF Antennas – Various — From The ARRL HF- and VHF-Yagi-antennas – HomeBrew — From DK7ZB Height Of Dipoles – Patterns By AA3RL. How to Design Off-Center-Fed Multiband Wire Antennas Using that Invisible Transformer in the Sky 66 Frank Witt AI1H.

Further information on antenna design and feed systems see The Radio Amateurs Handbook The ARRL Antenna Handbook Dr. Antennas Projects 201 ANTENNA BASICS very ham needs at least one antenna and most hams have built one.

Figure 2 10 meter 28-29 MHz free-space gain curves for the three wide-band Yagis. Controlled Impedance Cheap Antennas Kent WA5VJBs computer optimized 144MHz to 1296MHz antennas with a clever asymmetrical feed. Yagi Antenna Design by James L.

Physical design of Yagi antennas by David B. Note 688 Yagi Uda Antenna Designer RothammelDL6WU Filter Designer Audio AF Lowpass Filters. Here seven bullet-proof yagi from 3 to 8 elements from 25 to 19 meter boom.

Lawsons Yagi Antenna Design ARRL or Bill Orrs Radio Engineers Handbook to name only a few. At the peaks of. Based on Rothammel DL6WU.

The Quagi Antenna Turns 40 Wayne N6NB invented the Quagi an easy to build cross between a Yagi and a Quad. The ease of obtaining parts has made this a popular choice for thousands of hams. YW comes with the ARRL Antenna Book.

Specifying a Gain 216 dBd or a Boom Length 39 λ will limit the design to 216 dBd Gain and Boom Length to 39 λ. HenTenna– From The N4UJW Antenna Design Lab New HF Antenna From HB9ABX– new revolutionary design allows construction of small HF antennas to provide the same efficiency as large antennas. ARRL The National Association for Amateur Radio 225 Main Street Newington CT 06111-1400 USA Tel.

Resources listed under Antenna Calculators category belongs to Antennas main collection and get reviewed and rated by amateur radio operators. Introduction to the QY4 Yagi Design Program. There is no one best VHF or UHF antenna design for all purposes.

All are designed with one goal in the mind to maintain a solid gain and FB and SWR ratio over the band. Antenna design calculators category is a curation of 90 web resources on Magnetic Loop Antenna Calculator Spreadsheet Coil-Shortened Vertical Antenna Calculator Magnetic Loop Excel sheet. Explaining further antennas go through impedance varia-.

For example a yagi antenna for 50 MHz would have elements that are around 8 – 10 feet 25 – 3 M long. So who wants to build one should better buy the ARRL Antenna Book. This page is a JavaScript enhanced web page that implements the design of an antenna in the VHF UHF and Microwave frequency range with High Gain 118 to 216 dBd and Long Boom Lengths 22 to 39 Wavelengths.

By combining information found on transmission lines and antennas in The ARRL Antenna Book a design concept may be realized. I like to use dBi because it is relatively unambiguous.
