Le modèle BIG SIGNAL DL-4010 est une conception innovante d'antenne Delta Loop multibande haute performance composée de 2 boucles de pleine longueur d'onde de 40 et 20 mètres, qui à leur tour sont facilement adaptables dans leurs harmoniques telles que 40, 20, 15 , 10 et 6 mètres.. The DXZone merges amateur radio and Internet, since early internet days. Highest point of inverted V is 35â. - none Post navigation êÈ ®zßÕ]~ºïõ,år)K Brand: Wire Antennas UK Product Code: 40m - 10 m Multi Band Delta Loop DX antenna. The affect is obvious on the adjacent EZNEC plot of antenna current. The antenna has been used very successfully over the 2007-2011 period during the sun spot minimum. 160 m loop on 80, 80 m loop on 40, 20 m loop on 10, etc. It worked! Quiero comentar que no tengo ninguna experiencia en alimentar antenas con linea paralela, pero me gustaría aprender sobre el tema porque en un proyecto que tengo en mente necesito vuestra ayuda. Highest point of loop is 22â. I cut a 6 foot section of wire out of the loop, half-way around the 40m loop as a daring experiment to give me a halo dipole for 80m. Thanks! Kindly share it with your friends and social media circles. I used 1.05% and the correct formula to calculate this length in feet is to divide 982.8 by the frequency in Mega Hertz (982.8/7.150=137.45â²). This antenna normally has about a 3 DB gain over a 1/2 wave center fed dipole. 74 - Collinear Array Antenna for 40m, 30m, 20m 75 - 160m Inverted Delta Loop 76 - Half Rhombic Unidirectional Vertical for 20m to 6m 77 - Capacitance Loaded Vertical Antenna for 160m 78 - Fan Dipole Antenna for 80m to 6m 79 - Wire Ground Plane Antenna 80 - Inverted Delta Loop Antenna for 160m 81 - Inverted-L for 160m Instructions for building a 40m Mono-Delta-Loop 40m Delta-Mono-Loop.pdf PDF-Dokument [389.3 KB] 80m Loop on 18m Spiderbeam Fiberglass Spiderpole I just did a quick estimation to see if it might work on this short of a pole. The DXZone is the largest human created and maintained library of web sites dedicated to Amateur Radio, currently lists 20.000+ links organized into 600+ categories and subcategories. It is more difficult to assess forward gain, since you have to be sure that the received signal is coming from the direction of maximum gain. They all had huge pileups and I broke every single one of them either on first or second call. Our 40m Delta Loop antenna is installed in a residential neighborhood with many potential noise sources close by; most of which will tend to be vertically polarized. The 40m delta loop is still the best aerial Iâve used for inter-G and western EU QSOs, the height was perfect for NVIS and when I had it up, we were at the peak of the solar cycle and there were special event stations on 40m every single weekend. I put its apex at 50ft agl. The Horizontally Polarized version of the antenna will be less sensitive to these local noise sources which gives it a further advantage in this situation. According to ON4UNâs Low Band DXing book, the proper length for a delta loop should be 1.05% to 1.06% wavelength. A year later, I started phase-two. 5m Höhe gespannt wird. 40m - 10 m Multi Band Delta Loop DX antenna. Established in 1996 as a radio-related-mailinglist, has registered its domain name in 1998. La antena Delta loop es una antena eficaz de alto rendimiento y bajo ruido de facil instalación. As a preventative measure, my next door neighbor trimmed one of the trees along our property line. If you are looking for commercial products, you can visit the Delta Loop Antenna Manufacturers page. Mensajes: 1772. Ugh! Freespace is the point of maximum delta gain advantage over a dipole at the same mean height. Delta Loop antennas features particular triangular shape with equal length sides, and characteristics that make these antennas suitable for portable and fixed use. The Delta Loop is not only a great transmitting antenna but a low noise receiving antenna. The complete project was a lot of fun, since not only the result was very encouraging, also the way to the finish line was very interesting . hi DOWNLOAD HERE >> 40m 2-ele delta loop << Remember, DONâT email me, but comment on the channel. HORIZONTAL LOOP ANTENNA CONSTRUCTION . However, you may find that your mono band delta loop may tune up on it's second harmonic at a higher frequency eg. Notice also that the tower strongly interacts with the loop on 15 meters which does not occur on 40 meters. Several ham radio operators adopt delta loop wire antennas and array of delta loop antennas during their portable operations, being very easy to build and set up. The following is an article which I wrote and was published in the February 2013 edition of the Central Coast ARC ⦠We have several other Delta Loop Antenna Projects for 40 Meters you should consider to give a look, as well as other Antenna Projects for 40 Meters Band Son installation est réalisée en position verticale au sol avec une hauteur minimale requise de 8 mètres. 40m Compact 4-Square Antenna â EA5AVL. Delta Loops are mono band antennas, that works well also in their second harmonic. 7 Cool Delta Loop Antenna Projects for 40 meters, WSJT-X 2.3.0 new version available to download, Delta Loop Antenna Projects for 40 Meters, Top Amateur Radio links of the week Issue 1731, Top Amateur Radio links of the week Issue 1714. Delta Loop Antenna Projects for 40 Meters Band. 600 Watts. Save my name, email, and website in this browser for the next time I comment. L'antenne monofil monobande la plus performante du marché. The delta loop background noise level was 9 to 10 dB higher than on the Flag.
