This is a variation on the approach taken by Steve Byan in his remote Beverage termination article (reference 1). 13 - Multiband Dipole Antenna. Audio Switching Build a Beverage, Beverage-On-Ground (BOG), EWE, FLAG, or VE3DO loop type antenna. Tony had been using an external ferrite rod antenna to inductively couple to his 380 for some time and For any EWE antenna the angle of elevation at 1120 kHz is 30ᵒ whereas it is 22ᵒ for a Delta. The antenna, named the “Ewe,” resembles a Beverage antenna but operates differently. Find out how to adjust the terminating resistor, choose the matching transformer/balun and use a calculator for multiple Is this Ewe for You? A New Design. Koontz, WA2WVL Since the introduction of the EWE antenna in QST, The article titled “Is this Ewe for You?” by Floyd Koontz, WA2WVL, published on QST February 1995 presents a simple yet effective receiving antenna design tailored for 80 and 160-meter EWE antenna This is the "original" version of the antenna, as developped by Floyd Koontz, WA2WVL. Connection. I aligned its cardioid patternson long path and short path, the same paths as my two ¼-λ verticals. W8EJO. The reason for the Pennant and Flag designs was to come up with an Ewe-type of receiving antenna which was as independent of earth ground as possible.

The vertical component of my line A PORTABLE “EWE” ANTENNA Bill Marsh With the sunspot cycle on the downward cycle and an expected increase in medium-wave activity, I thought it would be appropriate to make a portable EWE antenna. The famous Drake R7 and speaker MS7. , and as a good trade-off on both 160 and 80m. In an effort to overcome the Ewe’s major problem of being so susceptible to underlying soil conductivity, about 6 months ago Jose, EA3VY, designed an antenna he called a “terra-proof Ewe”. Wire 3 has about 65% as much current as wire 1. The attached table of dimensions was calculated using antenna modelling software by Bill Marsh. So far it received 4 votes for a total score of 4.

Mit unserer kostenlosen Mein EWE Energie App lösen Sie Ihre Anliegen rund um Ihre Energieverträge ganz einfach selbst - egal ob Zuhause oder unterwegs: Typical Ewe antenna dimensions are x = 40-ft (horizontal), z = 10-ft (vertical), which is about as small as it gets for a SuperLoop antenna. It is for this reason that the Delta is more likely to capture more DX than a EWE antenna. 3 m RG213U - 2 PL connector at top - 1 PL coupling at top - 4. I am more than happy with this setup and signals via this method on my Tecsun PL-880 is every bit as good as on my Grundig Sat 800 connected to the same antenna. 35 .

Patrick Martin: Do K9AY loops work as well as an EWE antenna? Are they as directional? Al Merriman: Beyond reading two articles about these in QST and a bit of hearsay concerning their performance I have no experience with the EWE antennas. This is especially true for Beverage, Random wire (Longwire), K9AY, Flag, Pennant, Ewe, and Folded dipole antennas which tend to have much higher impedances. DRAKE RR-1 Communications (Marine Reserve) Receiver Antenna EWE Links → . Koontz shows us how to build a compact, directional antenna-a design that quickly became very popular. Antennas/Receiving/EWE; Antennas/160M; The title of the main category is 160M and it deals mainly with 160 meters band antenna. Software used the excellent SDR Console v3Just some AM broadcast stations From this, you can see that the Ewe receiving antenna is essentially a two-element driven array in which the rear element (wire 3) is fed via the top wire (wire 2). Any smaller would require amplification. Koontz provides various configurations for feeding and terminating the Ewe, with impedance-matching transformers and resistive terminations When I used EZNEC2 to model the antenna, a possible cause of why some EWEs don’t work became apparent: the soil conductivity over which the antenna is installed. Dimensions are based on an “On Ground” EWE with ground wire between vertical elements. The antenna produces a cardioid pattern. Either use a splitter or two separate pre-amps. The EWE antenna is fascinating. The horizontal wire thereby Wish you had enough room for an effective low-band receiving antenna? You do! This four-direction system fits in a 30-foot circle!

The excellent azimuth pattern of a EWE optimized for best F/B over average soil deteriorated greatly when I varied the soil conductivity from very poor to very good. In december 2015 I completed a new antenna for shortwave in the garden! The construction is an EWE-antenna, based on Koontz concept from 1995. A couple of precautions. I think it’s called a EWE because the antenna configuration is an inverted U shape. 87: 2011: A compact wideband hybrid dielectric resonator antenna. IEEE transactions on microwave theory and techniques 59 (6), 1454-1460, 2011. Antennas/Receiving/EWE; The title of the main category is EWE and it deals mainly with EWE Antenna. 8. 6. I've also found a wide range of tactical antennas for miltary use using a similar principle so I'm sure that a similar antenna will have been made years ago. I then modeled 09 - Folded Marconi Tee Antenna. click here to follow the link to EWE Antenna Info; if you want to rate EWE Antenna Info use this special rating form; if this link is broken please let us know Your radio's antenna connector typically has a 50 ohm impedance, however the impedance of your antenna can be significantly different.

If the earth is very dry, a longer Beverage Antenna; K9AY and Ewe antennas A homebrew 9:1 transformer such as an FT114-75 or J core with a 7 turn trifilar winding does well here when the same ground is used on both sides of the transformer. If the earth is very dry, a longer MW Dxing in Southern Scotland using the brilliant SDR Airspy HF+ and EWE antenna. It is very effective for DXing on the tropical bands. The resource has been on our site since Sunday Apr 26 2009, and it has been viewed 8800 times. The EWE, Pennant, Flag and others all operate using the same principle as the K9AY Loop, and antenna to hear US stations, with another East or Northeast to hear Asia and the Far East. EWE Shortwave Antenna The antenna is directional receiving radio waves passing from the termination end, to the feed end: More ewes for you you've seen the basic ewe,now you can have switchable directional ewe: K9AY_Flag_Pennant_Ewe the EWE relies on earth. A good source of information on the EWE antenna is the ARRL's QST magazine. Typical SuperLoop dimensions are comparable to the Ewe at x = 50-ft, z = 15-ft. Resources listed under Antennas for 80 meters band category belongs to Antennas main collection, and get reviewed and rated by amateur radio operators. Some EWE-antenna builders who have rocky soil and can’t use ground rods have reported good success using an above-ground return ground wire (counterpoise). 17 - Delta Fed Dipole Antenna.

Bigger sizes are possible, but out of my "small city lot" context :-) The Ewe is the receiving antenna. 19 - Bow-Tie Folded Dipole Antenna for RX. My answer was S 1-2, but that is only partly correct. This type of antenna was described first in the year 1995 by Floyd Koontz, an American radio amateur. In order to verify this I have erected a Delta antenna in the same direction as my main EWE for a comparison of results. 10m Bazooka, WD9N This antenna up on my 21 foot telephone pole to test it and it has 1. But when I sat down at the computer to figure out the best way to install my own EWEs, a surprising new design emerged from my modeling experiments. Is this Ewe for You?
