Feb 03, 2019 · 2. The ability to decouple the loop from the radio by moving it farther away is sort of a poor man's RF gain control. If the radio is still overloading, move the loop away a bit. An additional option to the passive-tuned loop is the successful FSL or Ferrite Sleeve Loop antenna. It is compact. The loop antenna is designed primarily for the AM band, which utilises the 530 khz to 1620 khz section of the radio spectrum. Indeed there are two different types of loop antennas, The first of these is the ferrite bar as build into practically every portable radio, the other is wound on an air-core form, and is far less popular with radio ... Full Wave Loop Antenna 10M thru 80M -- From Western Canada's Ham Radio YL Site Loops-- From The ARRL Loop Antennas-- Plans for each Amateur Band Loop Antenna Forum-- Yahoo -- Needs subscribing but lots of info here Low Band Antennas-- From K3KY Mac Antenna Master Software Magnetic Loops for HF-- From W2BRI Apr 20, 2017 · HF Antennas Especially Stealth Models For Those In An HOA HF Antennas Especially stealth models for those in an HOA By Dave Land to build, can be made with small gauge wire For stealth applications (suggest 18ga black wire from Frys) Single band antenna when fed by MFJ1786 10-30 MHz Loop Several other models available . There are many ways to get the radio connected and matched to a magnetic loop antenna. Amongst all the army, delta, gamma, toroid and whatsoever feeds the simple inductive loop is widely used. Many sites state that a feed loop with a diameter of about 1/5 of the main loop will give the desired 50 Ohms match for the bands you want to cover. Aug 28, 2020 · The Stubby Antenna Carbon Fiber AM/FM Radio WRC Antenna is functional and intended for both AM and FM radio signals. The unique service the manufacturer offers can assure you to buy it. It comes with a 60-days money-back guarantee and a 1-year warranty. The paint is 100% high-quality, resistant to UV rays and direct sunlight exposure. Finally completed the AM loop antenna for our Onkyo TX-8011 receiver. The frame is made out of two pieces of 3/16" x 1-1/2" x 20" wood, ripped off a clear 2x4. I notched the center of the strips half way to form an X. one would build their own antenna, or try to find either a used, older Radio West loop or Space Magnet antenna, both pre-1980. Plans for building all sorts of mediumwave loop antennas are available through National Radio Club publications. The address is found later in this FAQ. A more advanced antenna is the "beverage" antenna.

T... Original AM Micropower Transmitter. The picture to the left is a high quality radio transmitter for the A.M. broadcast band. The transmitter legally operates with "micro-power" and will not set any distance records but, unlike simpler designs, the frequency stays put and the fidelity is excellent. If you listen to FM radio regularly, you can make a fixed antenna that will improve your reception. One of the simplest types of antenna you can build is a dipole antenna, which consists of two pieces of wire in line with one another and connected to a central feed. Calculate the length of the antenna. What is a magnetic loop? • Radio waves travel by a wave of electric and magnetic fields at 90 degrees to each other. • Our regular antennas work by "recieving" the electric field portion of the radio wave. A small current is transduced on the antenna and the reciever amplifies it and converts it to audio. Kaito AN-100 Tunable Passive AM Radio Loop Antenna for All Brands Like Kaito,Sony,Panasonic,Grundig and More. 4.1 out of 5 stars 217. $34.98 $ 34. 98 $39.99 $39.99. See full list on swling.com A loop must be constructed with an inductance that will resonate with the tuning capacitor inside the radio, and the resonant frequency range must correspond with the AM band of frequencies. The following formulas relate the number of turns of the coil and the cross sectional area, and will give the loop the correct inductance: C laims for this antenna state that it should function from 20 kHz to over 50 MHz, with nulls approaching 30 dB deep. (I have tested the loop from LW to the 30M ham band.) Further, a magnetic loop engages with the H field of a radio signal more so than the E field, allowing a different reception “view” of signals. AM/FM Radio Antenna For sale is a New AM/FM Loop Antenna with 3-Pin Mini Connector for the , &, Systems listed below Ideal for home audio receivers and home theater systems but works for a whole array of application Many antenna elmers note that DX performance is better on a delta with vertical polarization. To date my favorite portable vertical loops are full or 3/4 WL (See note 4 and 5. I must add that I was impressed with the stations I worked on 80m where the loop was 1/2WL). Have fun experimenting with loop antennas! Video walk through with directions for an easy to build AM FM antenna. A simple antenna design I found on the internet, once you find the right spot you will...

Plans are now available for electronic download in PDF format for only $5 Photos and Reviews from Customers. Our AM RADIO DX LOOP ANTENNA converts your portable transistor radio into a long distance receiver, capable of pulling in distant AM radio stations. Works with any portable radio, without complicated connections. From the amp is a short pigtail with a 1/8" stereo plug. You get two attachments, a loop-stick booster and one two lead pigtail with alligator clips. The DE1103 has a 1/8" antenna jack and the loop plugs in direct for SW and FM. For AM MW BC you use the loop booster, which is fun to play with. IF YOU USE A TUNER, THE ONLY COAX YOU SHOULD USE IS BETWEEN IT AND THE RADIO OR AMPLIFIER. A tuner is only suitable to two types of antenna viz. 1) a single long wire using ground as the counterpoise and 2) a balanced antenna of some kind. Even though this is an unbalanced tuner, there is little point using an unbalanced output (coax). I am curious whether the shape and size of the loop is critical to the efficiency of the AM reception and how you determined the optimum design. For those that don’t have any engineering or science background, it would help to show how the antenna is connected to the radio, perhaps even several different radios to demonstrate different means ... Mar 23, 2018 · The rotor on the loop does not change the polarization. It simply allows me to rotate the loop around the vertical axis. This allows me to ensure that I am not trying to have a QSO with somebody that is in the nulls of the antenna. These nulls are approx. plus/minus 7.5 degrees, and are located perpendicular to the plane of the loop.

Note the loop stick is held by hand without a handle, this reduced the overall size and still produced an good null. Comparison of a 30 turn loop left Vs a 50 turn loop right. The 50 turn antenna had more gain. The nulls were about the same. I recently had occasion to do extensive loop antenna testing in a controlled, laboratory environment. I was working at a higher frequency, but the mathematics and behavior of loops is identical to the behavior of AM loops. Because I was dealing with very small loops, I could make as many loop antennas as I wanted - and they were easy to deal with.
