Characteristics: It is more or less omni-directional, and horizontally polarized. Here is a 6 meter magnetic loop that I purchased from Bob, VE3UK. Conditions are expected to improve in the near future as Solar Cycle 24 progresses, so it seems a good time to add a 6 meter antenna. Half Delta Loop Antenna. 6 Constructing the Loop Antenna Loop antennas can be built in a number of different ways. These antennas represent a radical departure from previous attempts to design a horizontally polarized omnidirectional antenna. WHY USE A FULL WAVE HORIZONTAL LOOP INSTEAD OF A DIPOLE ON 160, 80, 75, 60 and 40 METERS? (Rev 6/2017) A dipole antenna just will not work unless it is at a sufficient height. by Gene Preston, K5GP I read Rick Littlefield’s article in the June 2008 issue of QST on off center fed dipoles and was intrigued by the idea that the antenna could be extended to cover 80 meters. The 10-meter version of this antenna provides good performance and is just as easy to build. Element measures around 12 to 13 inches in diameter. The model was created assuming that the feedpoint impedance was 112 Ω, and that the bottom of the antenna with the balun was at a height of 2m above the ground.

Adventures with an 80 Meter Loop Antenna, Part 2: Adding a 1:4 Current Balun (Guanella Balun) In my previous 80-meter loop post , I showed that the measured SWR and the predicted power loss for the (roughly) 100 foot coax-only feed looks like this: Any 160 meter mobile antenna will have very poor efficiency, perhaps as low as . The loop is now complete. I used 75 ohm coax, (rg11), because of the close match to the 90 to100 ohm feed point. For example, if we wanted our loop to receive on 27. The hot side of the feed system includes a grounded matching element, allowing for a direct 50-ohm feed with coax. 160m …Building the 6 Meter Moxon Antenna. Connect an appropriate length of coax cable between the connector and your receiver's antenna input. The Antenna Is Resonant On The 15 Meter Band But Requires A Tuner On Other Bands. Just for trial, I made a couple of QSOs on 20m to have a comparison with the 3 element beam, directed at the stations. This will give the length for the used wire in meters. Delta Loop Antenna. A really good one perhaps 1%. While a long wire antenna gives a pattern that breaks up into lobes, folding the same To cut the antenna wire length to resonance we use the formula: Length (in feet) = 1005 divided by frequency (in MHz).

Once you have installed the antenna 4 Stealth antennas for the loft Table 4. 0 demonstrated that an indoor magnetic loop antenna was only around one to two S-units lower, on both transmit and receive, than an outdoor full size quarter wave vertical antenna. The antenna is essentially a tuned circuit with the inductor formed by a loop of wire measuring less than 1/4 wavelength in circumference and resonated to the operating frequency with a capacitor. Solder the other end of the wire, and the shield pigtails at each end of the coax loop, to the outer part of the connector. The second area in which a long wire loop offers advantages is in azimuthal coverage. The 6m band is his most popular one, since he get best results on this band. Many thanks! That was a nice easy project and the Dipole Easy and cheap to build, can be made with small gauge wire For stealth applications (suggest 18ga black wire from Frys) Single band antenna when fed by coax I read Yet Another Delta Loop Antenna, authored by WB3AYW, an experienced antenna specialist, and I was getting mentally prepared for my antenna building journey. com. 72m “All of my antennas are built by RadioWavZ. 555 Mhz we would divide 1005 / 27.

Standard 2 inch antenna clamps were used to attach to the boom. The dimensions of the Delta loop can be calculated by 306. If you reduce that spacing under 37", the same procedures apply here with the smaller antenna now having a bigger antenna (and more blockage) protruding into its collecting area, which is smaller to begin with. connector Transformation I had initially planned on replacing all of the mast pipe with new stuff, but after pulling the one 6 meter loop and VHF vertical off of the antenna, I figured I would just continue to use the existing mast. Quad element . Divide 1005 by Frequency in Mhz will give you length in feet. 6m Band HO Loop Antenna Our new HO LOOP is a result of a continued evaluation and development on reduced size, omnidirectional HORIZONTALLY polarized loops.

In 2 years I worked 38 states and 6 or 7 foreign countries on six. Full-wave loop antennas can be large at lower frequencies, but they are quieter than dipoles and have more gain broadside to the plane of the loop. Even an antenna 13 feet in overall (electrical) length will require an inductor in the neighborhood of 600 uH. As a interested radioamateur to operate on 6 meters it will be nice to work with a simple antenna for 6 meters. If needed, it can be disassembled into a very small bundle no longer than the longest element. Whoa!, I thought.
