Newbie questions regarding Blue and ferrit antennas

[JamesPatterson]

If you don't want to spend much money, I'd recommend building loop antennas with transformers. Cost less (Material costs <10€) and have better RF properties than ferrite antennas.
I guess you have to wait until the announcement of blue for more informations about price and conditions.

It's Good Idea but i need any other project plans with low cost invesments.
