Unlike some other directional antennas like a Yagi, the loop antenna is used in the null mode minimum signal because the null mode can provide a very sharp bearing, readable to plus or minus five degrees.Outlook 2010 mapi over http
The Loop Antenna has the advantage of being less affected by reflection signals due to its Faraday shield. By itself, the loop can provide the entire antenna requirement for direction finding provided the signal is strong enough to be received by the untuned loop.
If the signal is too weak, a Yagi is recommended for its directional gain. If the signal is too strong, the use of an attenuator may be required Offset Fox Hunt Attenuator.
Radio Direction Finding is an art, not a science. It requires skill. You may need to practice to acquire that skill.How to connect to access database in uipath

There are plenty of other sites on the web that do that. Where I can, I will point out links to more information on these antennas.
I will go a little more into detail on the antennas which are currently available on the market as kits, or assembled antennas. These include the Spiderbeam and the Hex Beam. I will not cover the Quad or Delta Loop in detail, becuse these are 3-dimensional antennas, and are much more complex to build than the Spiderbeam or Hex Beam.
Where I can, I will show links to more information on these antennas. It is basically a folded X-Beam, and very compact. This was the very first wire beam that I ever built. I got mine to work, at least a little bit, but I could not keep it working. The material I used was too flemsy and it kept collapsing. Like the Quad and Delta Loop, this antenna is a 3-dimensional antenna, which is partly what makes building it so difficult.
There are easier antennas to build than the Bird Cage, but it is probably the smallest Wire Beam of all. This antenna kind of resembles a bird cage, and since Dick's surname was "Bird", this antenna was called the Bird Cage Antenna. In my 50 years on the air, I have only spoken with a few OM who actually were using this antenna. Most of the 2-dimensional antennas e. Spiderbeam, Hex Beam, etc. Dick Bird took this serious. After the Bird Cage, he designed the Bird Yagi. The Bird Yagi is a Full-Size Yagi, whose parasitic elements ends are bent back towards the driven element.
Performance of this antenna is very close to that of a classical monoband Yagi. By using 4 fiberglass "arms" spreaders and wire elements, Dick was able to design a wire beam that was both robust and functional. The Spiderbeam is basically the same antenna. Unlike typical Yagi antennas with half-wavelength elements, the elements of the Quad and the Delta Loop are a full-wavelength long. Formerly there were companies selling Delta Loop antennas commercially, but I haven't seen any recently.

Hi I was wondering if you guys could answer a question about loop antennas.
I did check previous posts about antennas. What I would like to know are the loop antennas directional. That is can they focus the energy in a certain direction. I am in an apartment so any antenna I use copper jpole is on my patio wood fence. The repeater I want to hit is 50 feet high and transmits 25 watts and it is 35 miles across a lake.
I can hear the repeater but I cannot hit it and I have 55 watts. The antenna you have should work provided the other antenna is line of sight. K0PJSSep 30, Rotate the ant while receiving, for best signal. The loop should be edgewise.Paramecium population growth lab
If the face of the loop is toward the xmitter, the field will induce the same voltage in each vertical leg, so around the loop the voltages cancel.
That's how I remember it. Reflections can affect the directivity a bit. If you can't hit the repeater check your offset and tone. K8ERVSep 30, A repeater antenna at 50 feet is mighty low. You can't change that. I don't think a loop is going to help you. If your wooden fence is sturdy, you should be able to support a 20 foot pole with it.
I once supported a 40 foot push-up pole with a J-pole at the top with a 5 foot high privacy fence, no guying and it survived MPH winds. Use the 4X4 post. A 2 meter handheld yagi doesn't have to be big and cumbersome, and it doesn't have to be handheld. For an apartment dwelling a camera tripod could double as an antenna mount, or better yet some non-conductive PVC tripod held together with whatever means you can fabricate.
One yagi solution would be to frame the antenna with small diameter PVC tubing and tie wrap simple copper wires in place for the reflector, director, and driven elements. OH, btw It looks like the yagi is what I was looking for. It is 50 degrees and 34 miles across the lake.
Heath I saw a Video on utube about the arrow antenna and he used a tripod with an attachment to flip the antenna to change the polarity. My radio finds the offset and tone automatically.
2M HO LOOP, 144-144.5 MHz
You only need to set the offset or the tone if the repeater has a non standard tone or offset. Make sure that's what it is set to. Sometimes, a repeater will transmit no tone or even a different tone, so the tone scan function on a radio won't choose the correct tone for the input.
