WebA loop antenna is an antenna primarily for the AM broadcast and the Longwave bands. There are two different types of loop antennas, one is the ferrite bar (as in your am radio), … WebThe Moebius type was typically about 3dB lower in level. The second plot shows the Moebius loop relative level when the 1:1 transformer is swapped for a 8:1 transformer presenting a 400 Ohm load to the loop. The next plot shows the relative levels of the loops terminated in 50 Ohms and additionally the Moebius type when terminated in 400Ohms.

"WebThe WRTH editions give the erroneous impression that T2FD antennas require a 500 ohm resistor and a 10:1 balun transformer, used with 50 ohm coax cable. This is not the case, although these values will work fine if you have the 10:1 balun available (normally hard to come by). A T2FD built with 75 ohm coax (RG59 or RG6), a common 4:1 balun ...
