hi i have seen these with a tuning cap and one big loop with a single wind inside it but you always end up with two terminals i was wondering you hook one to your ant. conection on your set where does the other go? not to ground i wouldn't think or is it just for sets with dipole ant. connections.butch

Usually it would be a ground, if it is one of those large loops used (or like those used) on some 1920's vintage sets, or if your radio had two terminals marked specific for loop installation.

Other older radios that have an antenna and a ground sometimes use the ground connection as the other half of the dipole, or sometimes that is effectively accomplished through house wiring (some of the older radios worked better with no ground, ground attached to the antenna while the antenna was attached to the ground, sometimes no difference at all whether the ground is attached or not as sufficient coupling to a "ground reference" is achieved through the house wiring).

It varies by the radio.

An alternate connection would be to attach a long wire to the side of the winding the capacitor is on (capacitor performs fine matching) and the other terminal to ground, and a radio with it's own RF coil at the antenna stage, or built in loop, or even a modern transistor radio can be placed within the loop and that single wind oriented parallel to the loop, coil or loopstick windings gives you the coupling for that long antenna wireto that radio. it is just a large transformer.

hi john and thanks for replying the reason i asked was i had tried one of these and it worked well on my majestic 132 with one wire attached to the ant. conection but i tried the other to the ground connection and it seemed to cut the signal in half.i guess your right it varies with the different sets.butch

I had come across a schematic for a set that was available with a loop and without, and there were a few minor circuit differences, so your may have been one intended for a long wire. But, as is true today is what was true back then, use the combination that works the best.
