@dl3jop @dereksgc I didn't replace it. I sewed it onto the original.

My fully portable L and S band handheld satellite tracker, assembled from modules (for HRPT satellites and more). The dish, is made from an umbrella, with a slight modification and can be closed, making it completely portable. @dereksgc

@CoxCranio @dereksgc I calculated the dimensions using an online calculator, but both helixes require manual tuning for the maximum result, both the coils and the joining points, so it is not necessary to give dimensions, because every single piece made will have a different size :)

@alpha_adhito @dereksgc They would interfere with each other if I tuned them separately. They are tuned at the same time, they align with each other. If, for example, I remove one of them, the other one goes out of tune. The two keep each other in balance.
