Soldered Antenna problems?

[Jacobrichards91]

So i replaced a broken stock antenna to my phantom transmitter with another stock antenna. I connected them by soldering the two wires. Today i went out to fly and i was out about 200ft and it went into fail safe. Any suggestions ideas why it would do that?
