Re: inmarsat Acars L-band antenna #Beginner
I very much doubt if an antenna designed for 2.4GHz would be suitable for L band Acars (1.5GHz).
I know you say you are void of any special knowledge for building antenna but they really are easy so why not have a go.
here is a basic design for a suitable helix but take note the helix must be wound in the opposite direction to the article if you are using it without a dish
Another point is, L band acars is sent in two modes 10500 bit per second and 1200 bits per second, without a dish you will probably only be able to receive the 1200 bps mode - that was certainly my case when I was receiving data from the Alphasat satellite.
