Amateur Radio is a fun hobby and I am a licensed Extra Class radio operator with the callsign N1NPK. I really enjoy DXing (contacting long distance stations for the non-radio folks) and usually do it on 20 meters with this $20 homebrew yagi antenna. I have made radio contacts on all the continents except Anarctica with this inexpensive antenna and many of those contacts have been with 5 to 20 watts. Details of antenna here.
