HF 1:4 balun


hf-balun-case2Some years ago a friend offered me an HF radio: an Icom IC-730. I decided to buy it, since I didn’t have a HF rig yet. I gave it a nice place on my shelf, connected some meters of wire on the antenna plug, and from that moment I sometimes listen to all kind of chirps and beeps. I recovered my Hamcomm modem to see some wxfax images and SSTV, I tried to follow CW QSO’s again, listened to some conversations in SSB, etc.

Although this is not bad at all, I wanted to participate again. Since I moved to Utrecht, my radio activity was very low. I didn’t have any antennas on the roof, which made it difficult to pick up this nice and interesting hobby again. But… after participating in the 2002 jamboree on the air I decided to revive my radio hobby. And since I moved back to the country late 2005, I had all opportunities to set up antenna’s.

The first HF antenna I wanted to build was a Windom Antenna. This antenna required a 1:4 balun, so I made one. — more →
