40m-10m Delta Loop Antenna by GU3WHN This simple broad band antenna is easy to build, has gain similar to that of a dipole and is tolerant of nearby objects. It can be erected in almost any configuration provided the wires are well separated otherwise it acts as a singe band broadband dipole. https://rsars.files.wordpress.com/2013/01/40m-10m-delta-loop-antenna-gu3whn-iss-1-3.pdf

A homemade magnetic loop for 10-17 meters by PA3FG Magnetic loop antennas are very compact hf antennas. If properly build they can be used for transmitting. There are already many good theories about them so i will keep this part of the story very short. http://homepage.tudelft.nl/9e08q/magneticloop/

Foldable Mag Loop 40m-17m by PAØWIT The small HF magnetic loop is made from standard aluminium profile purchased from a hardware store. The six main sections are 67cm (26.4") long, this length maximises the number of pieces that can be cut from two 2.5m (8.25 ft) lengths of aluminium square tube. https://rsars.files.wordpress.com/2013/01/40m-17m-foldable-mag-loop-pa0wit-iss-1-31.pdf

HF Receiving Loop by VK2ZAY This experiment was inspired by Peter VK2TPM's receiving loop experiments for 80 metres. My loop is a bit smaller than Peter's, a single turn, the circumference is 4 metres + a little for the aligator clip lead, made from medium gauge mains lamp cord ("zipcord" for the yanks). http://www.vk2zay.net/article/141

Magnetic Loop Antenna by LA6NCA For communications from 20 to 200 km is this small loop better or as good as a full size field mounted dipole. An HF whip antenna is also mounted on the car. The magnetic loop is fare better than the whip antenna. http://www.la6nca.net/homebrew/loop/index.htm

Magnetic loop antenna for 160 to 15 metres by VK3YE October 1997's Novice Notes looked at compact antennas that amateurs use to operate from confined locations. The smallest antenna described for 80 metres was a magnetic loop. This article provides all the details needed to build your own. http://home.alphalink.com.au/~parkerp/projects/projmag.htm

Magnetic loop HF antenna by G3XBM In the last few days I have been experimenting with an HF magnetic loop antenna for the first time. These antennas are well known and work well, but for some reason I've never used one apart from on 136 and 500kHz where I used an 80m square magnetic loop made from standard PVC covered wire. https://sites.google.com/site/g3xbmqrp3/antennas/magloop

Multiband Deltaloop by DL2HCB After a Qth change last year, I was fortunate to get permission for an outside antenna. The new antenna was built with the following considerations in mind: At least 10 - 20m coverage; Open wire feed to simplify matching ... http://www.zerobeat.net/g3ycc/dl2hcb.htm

Multiband Vertical Loop Antenna 10, 14, 21, 28 MHz by VE2AZX - The wave emitted by the vertical loop may be polarized vertical or horizontal depending on the feedpoint location. http://www.ve2azx.net/technical/AntenneLoop21MHz-3EN.pdf

Packing Crate Antenna by SMØVPO I have been placed in a situation where a landlord denied permission to erect an antenna. Any form of antenna was unreasonable, even a white-painted broom handle caused interference!! http://sm0vpo.altervista.org/antennas/crate.htm

Pedestrian mobile magnetic loop for 40 to 10 metres by VK3YE I've described a few magnetic loops for HF pedestrian mobile. This one is my favourite. It's light and robust enough to use for hours at a time yet performs well on the busiest HF bands. http://home.alphalink.com.au/~parkerp/projects/projmal.htm
|
Pedestrian mobile magnetic loop for 20 to 6 metres by VK3YE In 2012 I made a 40 centimetre diameter magnetic loop antenna for pedestrian mobile. Covering 21 to 50 MHz. I've since made a SummerLoop II using parts from the Original. http://home.alphalink.com.au/~parkerp/projects/projsum.htm

Portable Mag Loop For 40m-10m by G8ODE The square loop has 60cm sides and, with the capacitor, tunes from 7.0-30 MHz. The Faraday coupling loop is approximately 1/5 (2.4m + 10cm wire tails) of the circumference of the loop. It is better to make the loop slightlylonger and trim for an SWR of 1:1 (ref 50 ohms) on the lowest band. https://rsars.files.wordpress.com/2013/01/portable-hf-loop-40-10m-g8ode-iss-1-31.pdf

Portable Small "Magnetic" Transmitting Loop for 40-17 mtrs by N4SPP Mid-2012 I acquired a portable QRP rig: a Yeasu FT-817ND (HF + 2m + 70cm, 5 watt). So I needed a portable loop (40-20 or 40-10). Such loops are available commercially for several hundred euros/dollars. You can make one yourself for a fraction of that price. https://www.nonstopsystems.com/radio/frank_radio_antenna_magloop-small.htm

Raamantenne voor de 160, 80, 40, en de 20 meterband door PE1KQP Het concept van deze antenne is niet nieuw, maar door de goede verkrijgbaarheid en lage prijs van de zogenaamde hengelmasten ( 12 m lang ) is het mogelijk om een veelzijdige vakantie antenne te maken. http://pe1kqp.radiotreffen.nl/index.php?page=raamantenne/A>

Simple RG213 Mag Loop (30m-15m) by G8ODE Its amazing what you can do with a bit of spare coax and an old vintage brass 130PF capacitor with 1mm spacing.
During the Lighthouse weekend, when the local QRN was really bad, this simple loop was constructed and performed
remarkably well. https://rsars.files.wordpress.com/2013/01/simple-rg213-hf-loop-30m-15m-g8ode-iss-1-31.pdf

SMØVPO-style Spiral Loop Antennas by N4SPP This antenna is very compact: ≈ 120x120 cm (4x4 ft). It is basically a transformer loop antenna: it consists of a multi-turn tuned loop and a small feed loop. The tuned loop is spiral-wound and square, has about ¼ λ total wire length. https://www.nonstopsystems.com/radio/frank_radio_antenna_SM0VPO.htm

W9SCH's Rockloop Antenna by DL1GSJ Years ago I started experimenting on magnetic loops & Co; I like the idea of narrow resonant aerials. When I saw the rockloop I never believed it might work (Ohmic resistance of the wire). http://www.qsl.net/dl1gsj/html/rockloop.html
