When I am having trouble push an anntenna througha small guide I usually sparay the antenna with silicone so that it slides easily and then I straighten the antenna the best I can and put it in the freezer for a while to stiffen it up ( ok you people inthe back stop laughing it does work) you just have to be very ready when you take out the antenna because it will get very pliable again within a minute after coming out of the freezer. its not really stiff but stiff enough to be pushed through if you are quick about it.
