vhf antenna connector

[spanishmak]

I hooked up a vhf radio and had my nephew give me a radio check and he heard me but with alot of static (we were both at our houses 5 miles apart)but I do get the weather channels in good though
I am wondering if I might have put the connector on wrong.Can someone tell me how it gets put together,it comes with 1 teflon and 1 metal washer
THANX
