The antenna will be designed to operate in the 10, 20, 40 and 80 m bands.This excellent article covers all aspects of designing a resonant loop antenna, examining gain and radiation patterns, and describing practical notes on how to build this antenna.This antenna covers 80 to 6 meters with low feed point impedance and will work with most radios, with or without an antenna tuner.
It is approximately 100 feet long, can handle the legal limit, and is easy and inexpensive to build. It is similar to a G5RV but a much better performer especially on 20 meters. Library Of Mmana Antenna Files Full Size Lightweight TribanderThe spider beam is a full size lightweight tribander yagi for 201510m, made from fiberglass and wire. It has been specially developed as a highly efficient antenna for dx-pedition and portable use. To build this antenna you need a lot that is at least 100 feet across. Antenna covers all bands 80-10 meters 30, 17, 12 meter WARC Bands. This antenna works as a Full Wave Loop on 80 Meters and also works as a 2 wavelength open loop or Bi-Square on the 40 Meter band. He documented the design and construction plans for a portable antenna that can be built with relatively ordinary components. This article compare this magnetic loop with a full-sized wire antenna on 80 meters by VK3YE. The design was purposely based on a telescoping fibre glass fishing rod as this allows it to be easily stowed away in the car. The antenna is made from a 15, 500 ft roll of black 14 insulated stranded wire, about 120 small black wire ties, and maybe 30 or so large black wire ties. The antenna features double-coaxial-cable-wound traps having lower reactance and a higher quality factor (Q) than earlier coax-cable traps by W8NX. A selection of the top 5 HF wire antennas for the backyard and for multi-band operation. Library Of Mmana Antenna Files Install And OffersThe open-wire feed line dipole antenna is easy to install and offers surprising performance on several bands. You can install it in almost any configuration; it does not have to be strung in the traditional horizontal flat top. This antenna can be configured for several bands and can work in 3 or 4 bands mode. An ideal replacement for those half size antennas such as the 12 size G5RV and Windom 40. Consist of 6 vertical elements and 6 base radials with a single 50 Ohm feed line.
