Hi crew

i have 2 pacific aerials fitted to my boat they look to be the long reach range 1.8m with stainless steel ferules(the screw on bit).  One has a white tip and the other has a blue tip.  I am assuming one is 27meg and the other might be vhf.  I have new vhf and 27meg units but am not sure if my aerials have been operating correctly as I sometimes can't get some reception to transmit.  I think I could have them the wrong way around or may need to check the ferrule connection.

i have googled extensively but been unable to find out what the tip colour means on this brand, can any one help?

cheers
