   An 80-10 end-fed half-wave antenna can be a very good performing part of an HF station. But its performance depends heavily on a well-designed and carefully constructed 49:1 unun, which matches the long wire impedance to within tuning range of operation. But the perfor-mance of an end-fed antenna is also very dependent on height above ground.

   Inverted-L Rybakov antenna Drill a 3/16˝ hole in the unun top, about ¾˝ from the back of the enclosure. Install a flat washer onto a 3/16˝ eyebolt, and slip the eyebolt assembly through the hole. Secure the eye-bolt with another flat washer and a nut. This eyebolt can be used to hang the unun and relieve

   DIY. Worthwhile projects you can build on your own. 9:1 voltage unun. In a previous article, we discussed the end-fed antenna, and how it often exhibits a large im-pedance, anywhere from 1800 ohms to 5000 ohms. If your particular end-fed antenna exhibits. much lower impedance, like 450 ohms, or you’re attempting to match your 50-ohm coax to.

   The 49:1 side can be used for end fed resonant antennas, and the 9:1 side can be use for end fed random wire antennas for use over various HF bands with the use of a tuner. I created this antenna with portability and flexibility in mind.
