Connecting Component AM Receiver to Loop Antenna

Our antenna did not work on the pipe we used until we sanded the rust away on a small section under the clamp. Gosh, I thought this forum was for knowledgeable folks with experience to help people who don't know the answer. You might have to de-tune it slightly to receive the station you want. Sometimes the new antenna will overload the radio because it has so much gain. One is to add a fixed capacitor and a switch which places an additional 200pF or so capacitance in parallel with the existing variable capacitor. Well he was all excited about it as well, and we took the little radio and lay it next to the large coax that carried the radio signal out to the large tower, suddenly I had a major shortwave signal.

Modify that AMĀ antenna

The tuning range is determined by the ratio of minimum capacitance to the maximum capacitance. The two GaroliteĀ® squares had to go. 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. Move the coil near the radio until you hear the station improve. The chassis of the radio is metal, but the housing and particularly the panel against which the antenna was mounted were non-conductive, wood or plastic in later years. Connect one side of the wire to receiver ground, and the other to the center conductor of the connector.

AM loop antenna for my receiver

hook up am loop antenna

While doing more googling, I saw where some folks used a separate loop to inductively couple their loop antenna to their radio. There are three parts to this antenna system, and if you are an adept scrounger, it won't cost you anything. A more permanent installation can be made by drilling holes and routing the loop before soldering. Strip the outer insulation from both ends of the telephone cable. I had it stretched down a culvert that ran in back of my house. A Word About Loop Antenna Design All these loops involve a resonant tuned circuit made up by a multi-turn loop coil and a variable capacitor. A tight flat coil will result.

How to Build Several Easy Antennas for Amateur Radio

Back then a receiver had only two main functions: tuning radio signals and powering two speakers. As a general rule, I hook the inner wire from the loop to ground, and the outer wire to the signal input. When I attached it in place of the smaller loop, reception increased dramatically! The wire will be 22 gauge insulated telephone wire since that's what I have lying around. Increasing the wire spacing doesn't do a lot to reduce this extra capacitance. Cut all but the white wire on the left, and all but the black wire on the right, leaving just enough to connect the wires that remain.

The loop described above can be used as the inductive element to resonate with the capacitor and form the new stage. I now want to use a splitter and connect that same antenna to my. Hook an antenna and ground to the two turns and a diode and earphone on the tuned side for a cool crystal set. But, like you, I suspect the antenna is the issue. Notice that as the number of turns increases, the cross sectional area decreases, but the effect tapers off with increasing number of turns. Static electricity often occurs when you walk across a carpet and build up a charge like a capacitor , and then you discharge yourself to a metal surface. But - I also had a somewhat larger loop from an older radio that I had junked.

Make sure your smaller loop does not touch or short out to the antenna. It was not long before I located a professional loop, manufactured decades before, mounted in a precision fiber case, with a nice rotary pedastal. Then, aim the Loop Antenna in the direction of the radio station. The integer number of turns is listed in the first column. Also, when constructing the tuned main loop, does it make a difference whether the wires are precisely wound so that they are all in the same plane like winding carefully around a box so the turns don't actually touch each other or does a loop antenna work equally as well if i just randomly wind 17 turns with the wires touching each other? Slide the ferrite through the coil and find the position that gives the clearest reception. The tuning capacitor ground is hooked to ground, and the variable section is hooked to the antenna.

That loop was soon permanently attached to the back of the radio, sandwiched between two pieces of cardboard that had an attractive piece of art on them so it wouldn't look too bad. Maybe I could use this loop to strain my spaghetti. I have a recevier here that has a large loop mounted on the back with an adjustable cap on it.

Use the small handsaw to make eight, half-inch deep slots, one-half an inch apart on all four ends of the frame. And if you are really motivated, clean up your algebra book, and calculate the resulting C that you get! You may be surprised to learn that your 30-year-old Technics tuner, if it is in good working order, is likely much better than the tuner you would find in a brand-new stereo or surround-sound receiver especially the latter. There is an additional comment about the quality of the car radio itself, which could also be true in your particular case. Ferrite is the grayish-black metal portion of the antenna. Using that big thick 14 gauge wire, I make the connections to the capacitor and link switch.
