Dec 7, 2016 · This small loop antenna, just like other so-called "magloops," consists of a capacitor and inductor in a tuned circuit, with a similar pattern and current distribution. On the radio now remains only the controller and the antenna can be placed deducted. We highly recommend this product to look for an excellent 160-meter antenna for your home or commercial space. This allows magnetic loop antennas to be relatively small compared to other types of antennas, making them suitable for constrained spaces or portable applications. May 6, 2018 · Small Diameter Loop Antenna Eight Foot Diameter “Magnetic” Loop Excellent for nulling a single nearby RFI source RFI to be nulled must be vertically polarized and received via ground wave Superb antenna for precisely locating RFI sources Bi-directional figure-8 pattern 150º 3 dB beamwidth Feb 12, 2025 · Alpha Antenna 10-40 Meter 100W Base Magnetic Loop + Remote: 4: 2023-03-28: Palomar Engineers 160 Meter Loop Tune-a-tenna by WB4NWV B&W Broadband Dipole MFJ 1836H The MLA-T is a magnetic portable antenna for 160m, 80m and 40m. 73 Magazine 1970-2002. 5% (1/8th wavelength). June 1991) helped me understand what essential considerations I had to take into account. Jul 26, 2022 · jeri ellsworthhas started a video series devoted to building a magnetic loop antenna for the 160 and 80 meter bands the first video included after the break is an overview of the rationale behind a magnetic loop. Below is a diagram and some construction details. 8 MHz and 10. 6% at 2 MHz. Nevertheless, the love of experimenting with antennas played a critical part in the successful outcome of this homemade antenna project. Carr. Mar 19, 2016 · Frequency band: 160/80/40 Meters; Selected Design: Helically Loaded Fractional Wavelength Magnetic Loop, after K8NDS design[4]. Less than the ideal of 12. Practical Antenna Handbook - J. In the info we observed, the Chameleon “P” seemed to be the best of the crop. Efficiency drops to about 15% at 1. Another item on this website discussed antennas that amateurs use to operate from confined locations. Hutchinson. ARRL Antenna Handbook 1990-2007. . A magnetic loop is an extremely high-Q antenna with a very tight bandwidth (think ~5kHz on the 160m band), but they are tunable. ARRL Handbook 1990-2009. This is my 6 foot diameter magloop for 80 and 160 meters. I checked in to a loc components; the Alpha Loop; and the HG-1 Precis seem to be the leading brands. Amateur Radio Techniques - P. Whereas it is quite possible to use smaller diameter loops on the higher bands, the capacitance required for 160 meters at 1. More Antenna Classics - C. Other stations in the USA approximately 5000 km to 6500 km away could also hear the signal. The tripod supplied with the Chameleon is flimsy and subject to be blown over in even a mild wind, but the antenna itself seemed to have the best features. The smallest antenna described for 80 metres was a magnetic loop. Feb 20, 2025 · What is The Best 160 Meter Antenna? The MFJ- 1778 wire antenna is our top product on this list. The goals of the project were to provide an optimized antenna for 40m, 80m, 20m, and all other HF ham bands, in that order of priority. 9mhz, using a seven See full list on n1su. Nov 2, 2017 · So hacker of note and dedicated amateur radio operator [Jeri Ellsworth (AI6TK)] has started a video series devoted to building a magnetic loop antenna for the 160- and 80-meter bands. Description. I create a two turn outer loop to get down to 160 and it works very well. The first On 160 meters, though, her perimeter falls to about 9. However, this antenna was direct-driven from coaxial cable, rather than inductively or through a gamma match, as is typical with compact transmitting loop designs. Size: 4 feet diameter to 9 feet diameter, depending upon available materials, cost, and efficiency Jun 25, 2011 · * RJELOOP1 - calculates the efficiency and performance of small magnetic loop antennas * GRNDWAV3 - a ground wave propagation modelling program that calculates signal strength at a specified distance based on transmitting frequency, antenna efficiency and ground conditions. The loop's electrical characteristics, such as its inductance and capacitance, are carefully tuned to resonate at a specific frequency or within a narrow bandwidth. Listed under the Antennas/Magnetic Loop category that is about Magnetic Loop antennas. RSGB Handbook - 2007 - 2010 In the article below, I’d like to describe the theory and the mechanical build process for a 160m-long multiband loop antenna, including its support system, tuning, and SWR analysis. MFJ is a famous brand when it comes to antennas. The best DX was BD7 at 9538 km with a report of -25 dB (Not exactly band crunching). Hawker. Magnetic loop antenna for 160 - 15 metres. 6% at 1. In researching the effectiveness of multi-turn loops, much is written about the proximity effects of two turns and that such loops may only be marginally more efficient than a one turn loop of the same size and exhibit a similar restricted bandwidth. 9 MHz, so your 100 watt signal is now just 15 watts radiated (not the worst thing in the world), but the killer is the bandwidth at that point: It's just 2. Sep 10, 2015 · The cheapest solution for the 160m band is probably a magnetic loop antenna, but do be aware that these antennas are optimised for small space and low cost, and NOT for performance. In contrast to the MLA M here is a stepper motor in the housing for tuning. Why MFJ-1778is The Best Brand For 160 Meter Antenna?
