[View 35+] Stirile Antena 1

Download Images Library Photos and Pictures. Heres a neat 1:1 50 ohm balun for use on HF horizontal wire dipoles. It uses an AM radio ferrite rod, with 3x14 turns of wire. 10-14 turns should be good for 2-30MHz. I used 18SWG enammeled copper wire. It all fits in a small project box. Great for setting up portable. Homebrew 144 MHz Coaxial Dipole Antenna flower pot by Andrew VK1AD Homebrew 144 MHz Coaxial Dipole Antenna flower pot by Andrew VK1AD

I investigated several feed methods and selected a gamma match with a 10-80 pF mica compression trimmer capacitor (Arco 462 type) soldered to a 6 inch length of the ¼" tubing. At maximum capacitance, it barely brought the impedance 50 ohms and zero reactance. The back-to-back alligator clips are a temporary shorting bar.
