I'm a newbie upgrading to a 3GHz scanning system so I'm no looking round
for recommedations and feedback on antennas that perform up to 3GHz. I
would rather spend extra for a professional level antenna than go for a
cheaper option. The AOR DA5000 looks good but I'd appreciate any tips
before I start shelling out money. I'm currently scanning with a D130
discone which works well but it only goes up to 1300MHz. Thanks for any
advice.

Hi TG.

Well it depends very much on what you want to hear.
Is it ground or space trafic?

A broadband antenna or discone, is not a very good antenna, compaired to a
dedicated antenna for a smaller frequency area. If your planing to catch
some satellites, a broadband/discone is not the way to go, the gain
efficiency is simply too low.
