Hello, Bill !

Would your kind offer be still valid even today ?

I would gladly bear any resulting costs.

I look forward to your reply.

Hello Roland,

I'm not sure where you are but if you want, I can make you the antenna listed in Paul's reply. The only problem would be getting it to you if you are not in the UK or Europe. Let me know if you want me to.

Kind regards,
Bill - G4ERV

Hi Roland,
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

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.

i just found online a circular pol Helix antenna plus an omnidirectional 2.4

Both are described as WLAN antennas.
Can these be used also for receiving L-band wacars, please ?
If so, I intend to use with them also a suitable LNA as my coax cable is abt.

my rx is the funcube pro plus dongle.
Kindly advise - thank you very much in advance.
As I am utterly clumsy and void of any special knowledge I have to use a
suitable ready-made antenna,
patch or dish etc. I would appreciate very much your respective
recommendations !
