Share. 80 - Inverted Delta Loop Antenna for 160m. This is a presentation by Jim Brown K9YC. This gives a low impedance feed impedance and this matches nicely to 50 Ω feeder. In most contests, the activity seems to be in the lower portion of the Band. The vertical antenna I have has less than 8 radials – that is just the way it is going to be. I only added two radials, and they are both very short, probably about 66 feet long. by TopbandHams.com. In … 84 - Mini-Horse Yagi Antenna. Technically a true "longwire" needs to be at least one wavelength long, but Hams commonly call any end-fed wire a longwire or random wire antenna.

Einfache Antennen für das 160-m-Band Rudolf Klos – DK7PE Das 160-m-Band stellt mit seinen physikalischen Besonderheiten und den Anforderungen an die Betriebstechnik des Operators wohl die größte Herausforderung unter den Kurzwellenbändern dar. Tap to unmute. Use as inverted vee or sloper to be more compact. It worked well in it’s only test, and will be reconstructed. 40m - 80m - 160m … High Performance 160 Meter Transmitting Antennas The 125 foot vertical: the 160 meter gold standard at least 30-60 shallow buried 120 foot radials 4-square arrays of phased 125 foot verticals very high performance for both transmitting and receiving at least 30-60 shallow buried 120 foot radials for each vertical The formulas say to use a horizontal section of around 80-90 feet. Shorter than my 80 meter Broadband dipole, shorter than my ZS6BKW. I need to improve my EMI filtering on some of the lines entering the shack, to make sure I am choking common-mode RF in the 160 meter Band. In fact, all ¼-λ antennas fed against ground require a radial system if losses are to be kept low. These will considerably r.. £42.00 Also the most common format is for a half wave dipole. In this sloper, the shorter and more nearly vertical triangular fans of wire carry more current and radiate more on the higher frequency bands, 20 through 10 m. The longer fans carry more current and radiate more on the lower frequency bands, 40 through 160 m. However, it is important to understand that this antenna is a low-Q structure. 78 - Fan Dipole Antenna for 80m to 6m. That is just not going to happen on 160 at this location.

After a couple cuts, and measurements, I got the length down to about 127 feet total length. If you have the room, I always hear that a full-wave loop is a great antenna for 160 meters. . Long wire or random wire antennas are very simple antennas. ft.). Use on 160 Meters as Marconi with tuner and ground. I have about 30 feet of coax, and have a few ferrite beads on about 5 turns of the DXE-400MAX coax, just before it enters the house. I used 3.5 TPI to make tapping easier and to keep the losses down, 11 … Follow edited Nov 25 '19 at 19:16.

Like every antenna that exists, random or long wires … In fact, it turned out to be much shorter than the distance between the two trees I had planned to use as supports. They can come close to half wave antennas in efficiency, although efficiency decreases as they are made very long or installed closer to earth. It does not exhibit sharp Half Delta Loop Antenna. ( Log Out /  As the wire is lengthened, it is found that the radiation pattern becomes more complicated, but the maximum radiation, and hence also the pickup, aligns progressively with the line of the antenna. I wanted to work the Stew Perry 160m CW contest last weekend, so I reinstalled a 160 meter inverted-L. Usually ships within 6 to 10 days. •Use NEC to model antenna and predict inductance required to resonate the the antenna – or: Use Vector Analyzer to measure feedpoint Z of an existing antenna that’s too short, export data to SimSmith and predict inductance. This is made rfom 127ft of vertical wire, 6 127ft... 1000ft of 14ga AWG wire (7-strand) and some rope make one of the best performing antennas I've played with.

I mainly use it to work fellow PVRC Club members, late in HF Contests. Here is an SWR plot of the first attempt, with total length of 135 feet: As you can see, the SWR min is too low in frequency, which is to be expected, given the length. I keep hearing that an Inverted L is a decent antenna, but have never been fond of laying radial systems. Beware of this approach to an antenna ground. With a wire hanging in the air, that impedance is "infinity." EZ-wire it´s a antenna with 16 meters* long. I will surely be using it again in the CQ 160 meter contest in January.

When I started this project, I was still thinking about a “long antenna.” It turns out that this is now the shortest wire antenna (horizontally) that I have. One end goes straight into the rig, often with no feedline, and the other end in the air attached to something as high as you can find. But it worked surprisingly well. His material is always worth reading and digesting, and he is a recognized expert on EMI/RFI in the Ham Radio world. Random Wire Antenna Lengths. The longer it becomes the more directive it becomes in the line of the antenna wire. I had to bend the ends all around to fit my small lot. The most straightforward way to install a dipole is as a horizontal antenna, although this is by no means the only way. Hope to see you there.
