The TL501005 from TRM Microwave is a custom broadband balun transformer that operates from 20 to 240 MHz. It is a broadband feed to an antenna element dipole used in an array and suitable for UHF & VHF bands. A 50 ohm unbalanced transmission line is translated into the 100 ohm balanced line that the antenna feed requires. Other impedance ratios are available from 50 ohms balanced to 50 ohms unbalanced through 200 ohms balanced to 50 ohms unbalanced. It has been developed Ferrites & Microstrips.
