Magnetic Loop !!!
Hi !!.
I`ve just built a magnetic loop for 20m, it is 1 metre circumference and uses a coaxial capacitor (RG58... QRP operation!!!) , it receives very well but doesn`t transmit very well at all !!!!.....it loads but T/X isn`t up to R/X..... Any advice will be greatly appreciated..... Thanks.... Lee....G6ZSG.... |

You might want to try the loop in a horizontal configuration for omnidirectional work. You'll probably find that you can operate it horizontally just a few inches above the ground although I recommend a couple feet.

Lee,
Using the loop indoors, at ground-floor level, at 20MHz, on a groundwave path, is not inconsistent with what you get. Get it high-up, outdoors, and it will make a big difference. The capacitor is made from a length of coax. I wonder how long it is and how it is located relative to the loop? Wherever it is, being unbalanced coax it will unbalance the loop. But what worries me, the very thin coaxial inner conductor is in series with the main loop conductor. It may have a loss resistance several times greater than the large diameter main loop. You could be losing a lot of decibels. ---- Reg, G4FGQ. |

More compact too. 6 fit very nicely round 1. Bundle them up in a plastic bag to keep off the rain. ---- Reg, G4FGQ. |

Dear Lee (G6ZSG):
Please do note that I was commenting on a receiving antenna, which is in need of an antenna mounted amplifier. The amplifier does not have hard-to-accomplish requirements for gain (20 db is good) or for input impedance. However, the amplifier does need to have very high IM performance and at least a high-pass filter to reject signals from the AM broadcast band. Using a small, horizontal loop antenna as a transmitting antenna can be done. As you are finding out, coupling power into the loop is a challenge. Good luck. 73 Mac N8TT -- J.

The intermod performance of a receiving pre-amplifier is of no
consequence with a magloop. The Q and selectivity (of the order of 1000) of the loop at the wanted frequency easily reject local high-power MF broadcast frequencies. On 160m, It's difficult to hear any stations only 3 kHz away from the wanted frequency. ---- Reg. |

Dear Reg (G4FGQ):
I note with interest that your note was written in the early afternoon. The subject of my communication is: small (much smaller than a wavelength) - non-resonant (input impedance almost entirely inductive if one looks into a single opening in the loop) - horizontal - loop antenna (no substances with significant magnetic properties are in the vicinity of the loop antenna) - used to receive incident EM waves (which have both E and H components). SNRHL receiving antennas I do not know the definition of a "magloop." Apparently, such a beastie comprises a resonant loop antenna. No knowledgeable person would disagree that a single tuned network with a Q of 1000 is "narrow." My interest in SNRHL receiving antennas comes from an interest in practical HF receiving antennas that are resistive to types of noise that appear only to be present at isolated, open, rural, otherwise-low-noise sites. The noise involved does not occur in urban areas or even rural sites with many trees. Consider some of the excellent wine from Michigan this evening. This state, with a coastline almost the same length as that of the island of Great Britain, produces some excellent products for your enjoyment. 73 Mac N8TT -- J. Mc Laughlin; Michigan U.S.A.

Hello Lee,
Thanks for letting me know that by giving your magloop half-a-chance it performs according to expectations. You have also demonstrated that the G5RV is not so hot as it is made out to be by salesmen and they who have never tried anything else. No disrespect intended to G5RV himself, now deceased, who claimed only that it had a nice radiation pattern on 14.15 MHz which enabled him to work both Europe and North America from South America without having to climb ladders and change anything. The magloop is by far the most efficient of all the antennas of roughly the same physical size. Both theoretically and in practice. It will do even better if you can get it well above ground in the vertical plane. In the horizontal plane it works best at the higher heights, above surrounding obstructions like buildings. But in such surroundings there is room to erect full-size dipoles anyway, which will obviously do better still. The main disadvantage on the 160 and 80 meter bands is the size, physical and capacitance-wise, of the variable tuning capacitor. You need a vaccuum capacitor of about 1000 pF max. By correct choice of loop dimensions and minimum capacitor setting the 40 meter band can also be covered. On 40 meters a small magloop can be highly efficient. Investigate using program MAGLOOP4. Are you using the small internal coupling loop, about 1/5 diameter of main loop, to match to a 50-ohm feedline? This is the best and most simple way to go, A different ratio small loop diameter is needed for other feedline impedances. The circuit behaves as if the turns ratio on a transformer is being changed. Let us know how your experiments proceed. ---- Reg, G4FGQ. |
"J. Mc Laughlin" wrote Dear Reg (G4FGQ): I note with interest that your note was written in the early afternoon. ========================================== My Dear J. Mc Laughlin, Thank you for your interest in my early afternoon state of health. It is now 19.15 hours and I have just started on a bottle of Sierra Valley, Californian, Ruby Cabernet. The subject of my communication is: small (much smaller than a wavelength) - non-resonant (input impedance almost entirely inductive if one looks into a single opening in the loop) - horizontal - loop antenna (no substances with significant magnetic properties are in the vicinity of the loop antenna) - used to receive incident EM waves (which have both E and H components). SNRHL receiving antennas I do not know the definition of a "magloop." Apparently, such a beastie comprises a resonant loop antenna. ======================================= "Magloop" describes a small, single-turn, thick conductor, usually made from copper water pipe, circular, hexagonal or square in shape, loop. The two ends of the loop are connected together via a variable capacitor. The capacitor tunes the inductance of the loop to a resonant frequency at which everything happens. The term "magnetic" arises because the near-field of a transmitting loop is mainly magnetic as distinct from the electric field. On receive it is more sensitive the magnetic field than the electric field. ======================================= No knowledgeable person would disagree that a single tuned network with a Q of 1000 is "narrow." My interest in SNRHL receiving antennas comes from an interest in practical HF receiving antennas that are resistive to types of noise that appear only to be present at isolated, open, rural, otherwise-low-noise sites. The noise involved does not occur in urban areas or even rural sites with many trees. ===================================== The noise in rural, open, oceanic areas is just the same sort as in built-up, residential, city and industrial areas. It is all random but there is just a lot less of it. An antenna of any sort is just as sensitive to noise as it is to signals provided both noise and signals are coming from the same direction and elevation. ====================================== Consider some of the excellent wine from Michigan this evening. This state, with a coastline almost the same length as that of the island of Great Britain, produces some excellent products for your enjoyment. ======================================= Everybody has heard of the State of Michigan with its capital city of Detroit. I have always thought of it as an industrial state similar to my own area of the city of Birmingham and the surrounding Black Country of England. It is the manufacuring areas which produce the REAL wealth of this World of ours. Not forgetting the farmers. Never having had the opportunity to visit Michigan it has not occurred to me that the land could also grow grapes and produce wine. (Actually, we do produce respectable wine here in cool-climate industrial England. But not much of it.) It is now 20.00 hrs and too late to go shopping at my local super-market. Nevertherless, at my next visit I shall keep my eyes open for "Michigan" on the wine bottle labels. ---- Reg, G4FGQ. |
Hi Lee,
I'm a little confused about the bandwidth that you're getting. Maybe it can be attributed to losses which widen the SWR bandwidth. That's not necessarily a bad thing. I have used an AEA IsoLoop antenna that is about the same size as your loop antenna but has a low loss butterfly capacitor for tuning 10-30 MHz. On 20 meters the bandwidth is only about 20 or 30KHz(can't remember exactly since I haven't used it for a couple of years). It works great if you park yourself on a frequency but it is a pain to use for hunt and pounce. Besides the null using vertical polarization, is it possible that for your local friend you may have been cross-polarized. Usually direct wave cross-polarization is on the order 20db which accounts for the 2 to 3 S units of change from vertical to horizontal. Have fun with your new toy! 73 LT Hi Reg....

This is a case of a fractal GUARANTEED to perform worse than the basic antenna in all respects. That is unless a simple circle can be considered to be a zero-zero-order fractal. |
Walt,
We are all sentimentally attached to the area where we were born. I find it intriguing you were brought up in the same sort of industrial region as I was dragged up in. There are a few descriptive paragraphs in "A bit about Reg" in my website. Please forgive me for assuming the largest city of Detroit to be the political capital of Michigan when it is actually Lansing. Again there is a similarity. The political capital of Warwickshire is not the largest city of Birmingham but the small ancient town of Warwick with its castle, not far from Shakespeare's Stratford-upon-Avon. Is Michigan named after an Indian tribe? ---- Reg. |

Googling for info, I see a few suppliers with loading coils for a half size G5RV (complete with instructions), but could not find an article with physical dimensions and loading coil characteristics. Is this a "proprietary" antenna, not open to independent analysis. In its "normal" mode, a (full size) G5RV has feed system losses on 160m like cricket scores. Intuition suggests that a half-size G5RV (where everything is scaled to 50%) will have similarly appalling performance on 80m. Has anyone seen details of the loading coils for this "loaded half-sized G5RV', or models of its performance? Owen -- |
Michigan has had the most productive industry in the world.
It also has some of the most productive agricultural land - especially for being in the north. However, Michigan (and others) are going through a major change. The advent of fast, inexpensive communication and transportation have seen the movement of vast numbers of manufacturing jobs to areas where wages are low. Many square miles of factories have been pulled-down to bare ground. (Taxes are thus reduced - often next to impossible to sell the land because of unknown pollutants from 90 or more of industrial use.) Ascendant in Michigan are jobs that produce intellectual property, that are involved with higher education, and that are involved with medicine including research. The new worker is different. ========================================= Dear J. Birmingham and the Black Country has suffered a similar fate. Once upon a time EVERYTHING was made in Birmingham. I began work at the age of 14 in an electric motor factory. (I've never met a university professor.) Factories have now been converted to museums as an adjunct to the tourist trade. Only this very week, the last of the once-upon-a-time many Black Country iron foundries poured the last few tons of molten iron from its furnaces. Sadly, three months back the last of the 100-year old motor factories, which started with bicycles, closed its gates rendering 15,000 people redundent. Motor production is to continue in China.
