I agree with Stefan. A transformer (using a suitable core material 
such as 3C90) gives you more flexibility in the future It also 
provides the opportunity to isolate the RF ground from the mains 
supply ground which can improve EMC both on transmit and receive.

Well done so far. Your signal is very impressive with such low RF 
power.
