This antenna is certailnly better than the Degen, which I suppose its cost reflects. Its well made, and high frequency performance is certainly improved by using a 12V battery in place of the 9V one.
Its marginally better at 6Mhz , but at 9Mhz etc its really good, its easier to 'peak' having a wider peak. I think its also better at noise rejection, I often get decoded audio on 1 bar SNR on the Newstar rather than requiring 2 on the Degen. Delivery is quick from Australia too, paying via PayPal.
Its helped me listen to more stations than I have picked up before, in the 9-11-12 Mhz bands.
I will give more updates as I learn more
