Direction of signals CCW Loop
leslie norton
At last got my CCW loop up outside on a pole, its just above the roof in the clear.
Its mounted on top of a yeasu rotator and set up for direction where my previous loop was. The direction a normal loop receives is, simply put, when riding a bicycle the direction of the wheel is in the direction of the bicycle as is a loop antenna and signals. My question is the CCW loop direction of signals the same ? I hope it is as thats how i have set the rotator. Thanks Les

Hi Les,

The HF Active Loop antenna works the same as a conventional circular loop antenna so you are correct setting it up the same way as your previous loop. On skywave HF signals you will usually not see a definite null as the incoming signal is usually refracted off several points in the ionosphere. The polarisation is constantly changing as well. On local vertically polarised ground wave signals say a local medium wave station you should see a sharp null end on to the loop. To use your analogy the null is in the direction of travel of the bicycle wheel.

1st days (8 hours) results on FT8 receive, 20m, pretty respectable.

Considering HF conditions are a bit poor at this point of the sunspot cycle it's looking good!
