To do this, you need a scrap tuning capacitor from a discarded radio. If you carefully observe, you will notice with the ferrite inserted, the radio is most sensitive to stations broadside to the ferrite. The easy way is to buy or otherwise locate a length of insulated wire. But you don't have control over that. The Ferrite Bar Your solution might be as easy as installing a larger ferrite rod. I have used this for some time and am pleased with the results. The ends of the cable coming out the bottom should be of approximately equal length.

That is the reason for the ferrite. Thread the telephone cable through the plastic pipes and fittings, like stringing beads. Well, this antenna doesn't have to connect to the radio. If not, five bucks ought to do it. 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.

Connecting an AM or FM antenna

First, as in the old days, you need a long wire antenna. Notice that as the number of turns increases, the cross sectional area decreases, but the effect tapers off with increasing number of turns. Please feel free to us or leave a comment. The loop must be oriented vertically and has maximum reception in the plane of the loop. Especially if you are only after that one station! Ferrite is the grayish-black metal portion of the antenna. If not, or if there are components that interfere, don't try to replace it. My home-made circuit continuity tester has both a beeper and a light that come on when the circuit is closed.

How to Make a Loop Antenna for an AM Radio

If you are making a square loop, the third column is the length of each side. Ted updated September 21, 2017 Ted Tenny. The loop is offset to one side to limit the inductance - there is more in the center of the bar or rod, less near the end. A rotatable loop is going to be smaller and more turns, by necessity. Need 1, but 1 more is helpful. There is no absolute requirement for the number of turns to be an integer, you could tap off one side of the loop for the start, and the opposite side of the loop for the end, just use the formula. It should be fairly easy to loosen it and slide it out.

Connecting external AM and FM antennas

But - not just any loop will work. A wiring diagram that will describe how to install the external antenna. You can experiment with the diameter of the coil, the number of turns and the length of antenna wire you use. If your ferrite loop antenna has three or more wires going to it, you are not going to be able to directly substitute your loop antenna. The 2nd clip can be used to clip the longer piece of the wire around the metal stake to the shorter wire that is coiled and near your radio. If so, how much affect can it have? If you used a tuning capacitor from a discarded radio, it will have two sections, a big section and a small section.

Modify that AMĀ antenna

This is true, the larger the cross sectional area of the loop, the more sensitive it is, and the more stations the radio will receive. Tape it to the wall, or to a piece of cardboard propped against the wall. Form a three inch coil with seven turns. The coil intensifies the signal which is inductively picked up by the ferrite antenna inside the radio. Secure into a round shape with ties or tape. Radios were most sensitive to stations that were broadside to the plane of the loop.

If you examine that little loop inside your radio, you can quickly tell there is nothing close to 750 turns of wire. If you want to experiment with the loop antenna by adding windings to accomodate the converter, be my guest. If you don't have enough area, just increase the number of turns until you can make a loop fit. The original wooden frame was problematic to build and alas, not very substantial so I tried substituting plastic pipe for the wood, with the antenna wires on the inside. With the advent of the transistor radio, there soon ceased to be any way for you to connect your radio to an antenna. Any comments are welcome in helping me with this problem.

If you have been around for a while, you might remember a time before ferrite bar antennas were invented. The tuning capacitor ground is hooked to ground, and the variable section is hooked to the antenna. But without an external antenna, the station isn't usually all that far away. Installation is minimal, and leaves your hood with a clean, uncluttered look. The design looked right, but only by making one could I find out how good it was.
