I have a diamond antenna verticle for 2 meters and 70 centameters, it 
does have a rubber ring between the pieces, and it has two really 
small set screws to put the copper wire together inside the 
fiberglass.  It says that it has 9 db of gain.  I got it from 
universal radio.  I have had very good luck with it.  I am not 
exactly of the name of it I think it was  the Diamond 9.  I will have 
someone help me find the receipt if you want.At 12:48 PM 8/29/2013, you wrote:
