If I hold the antenna in the "middle" where the antenna wasn't making proper contact, I quickly lost many bars or dropped connection completely. The top (stub) end had this coil that you mention. I think its purpose is to extend the antenna electrical length to quarter wave... (It was 900MHz phone)
THANK YOU.. I was about to say the same thing except that I had owned two Samsung cellphones for YEARS that both had that same extending antennae arranged as you described it... and it worked GREAT when it was extended--it caught signal clear as a bell in areas MOST phones were crippled.
