This is so that the oscillating electric field of the incoming wave will impose the largest possible potential difference voltage between the ends of the antenna. I will amend the article. The Loop does a good job especially on 40, 80, and 160m bands. First, as in the old days, you need a long wire antenna. Is this station s you're wanting to hear a particularly low-power or low height transmitter? The receiving element itself is a 30 inch 78 cm square loop of the coax, so you will need to construct a suitably sized wooden frame, say 10 mm half an inch less each side of the wooden doweling around which you will wrap the coax - this is just to make allowances for the coax which will then be the correct size. The trap is easy to remove, however.

A dipole isn't going to give any gain over a quarter-wave vertical, and the vertical can be made fairly directional simply by angling it. A single 33 inch square 84cm turn of coax typically has around 5. Seems incomplete to my simple way of looking at it. A few years back I used to tape the shows from both these stations but signals are to bad to do this anymore. Move the coil near the radio until you hear the station improve.

Good FM/AM antenna for my reciever?

The wavelengths in the the citizen radio band were longer than the car-mounted whip antennas could easily accommodate. Our area is pretty mountainous so that probably has a lot to do with it. Especially with this new chip. Do you have any recommendations? Once I switched to the rabbit ears, the tuner locked right onto the signal, with a full set of signal-strength bars and crystal-clear reception. Very much worth the cost. So, in conclusion, this is aerial is very easy to construct.

Antennas: Broadcast FM

can i use am loop antenna for fm

When connecting a transmitter to an antenna, cable loss is very important. Is it before the detector? Since my brain cell is not functioning at full speed at the moment I am not able to perform any calculations which make sense to me. Commercial stuff selling, paid work etc. We are happy to assist further. If a radio's antenna is broken, use the following steps to make a simple new antenna out of household items. Make sure you insulate the copper though with thick tape though if you intend to hang the loop on tree branches. Our antenna did not work on the pipe we used until we sanded the rust away on a small section under the clamp.

I do not have a rotor on this setup, I merely rotated the antenna for least noise on 80 and 160, my primary bands of interest and put a nail in it. Do I need to disconnect the whip and wire one side of the dipole in place of it and connect the other side to the chassis?? Home theater receivers with poor tuners especially can benefit from an inexpensive antenna upgrade like this one. Or mount two antennas, aim each separately, run two wires with a switch at the set to choose between them. On a spiral loop antenna, the copper winding begins on the outside edge of the X and is wound in a spiral shape toward the center. The problem is, when I do look back at some of the articles I have written in the past, I just cringe with embarrassment.

Without the loop band noise was up around -95 dBm or S5. The receiving element itself is a 33 inch 84cm square loop of the coax, so you will need to construct a suitably sized wooden frame, say 10mm half an inch less each side of the wooden dowelling around which you will wrap the coax - this is to make allowances for the coax which will then be the correct size. Add or subtract six inches to resonate at either end of the band if you want to experiment, but this is fairly forgiving antenna and should cover the entire band very well. Maybe you're confusing them with helical antennas. Great for contesters to quickly check all bands.

Connecting an AM or FM antenna

Back then a receiver had only two main functions: tuning radio signals and powering two speakers. What I do not want to do in this article is delve into anything technical. And, if a gas is illuminated with light at a resonance wavelength, the gas will appear opaque black, even if the gas is very, very sparse very low pressure, near-vacuum. Here is a photo of what I am talking about:. Yesterday the boomboxs 3 in the house second story up I couldnt even find the station. The other end not shown of the coil will go to the ground stake so leave enough wire.

Sound Advice: The best radio antenna might not even be a radio antenna

Tape it to the wall, or to a piece of cardboard propped against the wall. I wish I could remember more information about the original calculations. Please tell me if you agree with this. I love the low noise of the receive loop and the fact that it receives from 2200 meters to 10 meters without any tuning. On some days it's best if I lay it on it's side, some days if I point it 90deg away from the station, some days when I point it up, some days when I point it down. I only listen to college stations, and fortunately in L. I have been singing the praises of this design for years and I often recommend this little antenna to newcomers to the hobby since they are so simple to put together and cost next to nothing.
