congrats on the license, you should have a call sign here pretty quick as the forms where mailed in on sat after the testing.
get one of these
I bought one of
the cable adapters, but going to get the above, as they look more durable. Wait, just bought one, will let you know if it fits here shortly. I got the cable version as I know that would give clearance to the volume knob.
Don't get me wrong the stock rubber ducky works fine, and thats what I have. But a full size 5/8 antenna will give you better range and clarity.
