N1LN What started off as a VERY slow night on 20 meters picked up quickly when I moved. WARNING to those whose antenna tuners don't provide a DC ground to both ladder line leads: Perhaps due to the fiberglass poles, this antenna collects large amounts of static electricity which gets carried down the ladder line to my shack. 2WL matching section of 450 ohm ladder-line will match the antenna pretty well on its intended single band frequency. After lots of very unscientific experimentation and observation, I ended up with: A multi-band vertical (Hy-gain AV-640) which I use as my 'reference' antenna, and a horizontal delta loop at about 40 feet. 1 - 40m dipole broadside gain patterns vs. Tomorrow I will also re-arrange my station a bit. the antenna's performance. Hamuniverse. Most of the contacts were on 40 meters, but 20 opened up long at 22 minutes after the start and got 4 contacts there. The 88′ EDZ was homebrewed and the Butternut is a commercial antenna, of course. Pornind de la această schemă, au fost construite de către radioamatori diferite variante, pentru îmbunătăţirea performanţelor. Although often treated as such[34, 25, 29], modeling these elements as random over the canopy height actually reflects the case demonstrated in Figure 1. Short dipoles and verticals (like a 44-ft vertical) will almost always model with very good efficiency. Although many people attempt to feed it with coax cable, I prefer to feed it with openwire feedline. 170' or so is an EDZ for 40m alrightit's a high-Z antenna so assume you'd feed it with ladder line; if so, you could short the shack ends of the line together to feed it as a top-loaded Marconi on 1. This means an EDZ for 15 or 10 meters is a practical portable antenna. Don't neglect radials. I was looking for more directionality on the 10 meter band, so I created an Extended Double Zepp (EDZ) antenna The object of this antenna: purportedly the 3 db gain, more directional, and to bypass a tuner. Right folks, it's been a while since I embarked on my tri-band 20, 17, and 15m Moxon project for the beach. Last year I posted results from a series of experiments on ground systems for vertical antennas. 1 By contrast, everyone knows about the family of antennas related to the half-wavelength dipole: the quarter-wavelength ground plane, the 2-, 3-, and more-element Yagis, the ZL-Special. They manufacture GPS trackers and supply them to various companies in many countries across the globe including USA, Mexico, Canada, and. You can go with a compromise antenna like a G5RV that will work reasonably well if you are strapped for grass and space, or build one of the other exotic designs that are spread out across the internet, like the Extended Double Zepp (EDZ) antenna that is two 5/8 wave antennas in phase with a vertical section made with ladder-line. The drum splits in order to load the toroid. _Lnt rOMELETl RHYMW6. An EDZ can work well but the peaks and nulls vary on every band and wind in the trees can be an issue. By varying the length of the 450 ohm ladder-line feeding the antenna, we can achieve an SWR of less than 2:1 on all frequencies on all HF bands with the exception of the lowest part of 80m. For 160m, I would recommend any kind of vertical antenna. You have a 1/8th wave vertical. IEEE Antennas and Propagation Magazine, Vol. Once again the antenna was shipped and received with in a few days. An EDZ is just what others would call a "five-eighths wavelength vertical", but here balanced as a dipole, not over ground as a vertical. 700 Did the verticals work ? Absolutely, I got significantly better reports, 3 to5 S units from various European stations as compared to the dipole and I had the same results with CA. Along came UT5FB/MM off the coast of Brazil, sideways to the beam. Not the whole profile section of profile 1 is mapped geologically and. Signals sounds louder and cleaner and are at least 5 to 7 S-units stronger compared to that produced by the Cobwebb and Vertical which are both omni-directional and at the same height above ground.

The double extended Zepp is a dipole type Antenna consisting of two collinear 0. As a matter of fact it probably has much more loss than a resonant antenna the same physical length that is lumped loaded, or that an Inverted L would have. So model comparisons of the two antennas will probably do a pretty good job at telling you how the two antennas would work at various elevation and azimuth angles something that you'd need a lot of free time and probably a helicopter to answer with measurements. Easy Installation and Configuration. It's unclear what Diamond Antenna was thinking when designing their promotional information. After lots of very unscientific experimentation and observation, I ended up with: A multi-band vertical (Hy-gain AV-640) which I use as my 'reference' antenna, and a horizontal delta loop at about 40 feet. It is inversely proportional to the frequency which means the wave with higher frequency will have shorter wavelength. The peak current at a position well above the top of the short antenna is said to give the longer monopole a lower-angle of radiation and additional gain. Featured Shop Tours. Jan 7, 2017 - 11 m Band Extended Double Zeppelin 'Zepp' (EDZ) antenna centred at 27. From the limited design information that I have found, I am thinking of 3/4 wavelength on each side with a horizontal separation angle of either 72 degrees or 120 degrees.
