We offer Current type BALUNs for antennas operating from 1.8-450 MHz, Our products are broadband units covering a huge portion of the frequency spectrum or single band units covering a small portion of the frequency spectrum with exceptional performances. Our Current Type BALUNs are carefully designed and measured for maximum resistive choking impedance over the bandwidth desired. If you still do not know why your antenna needs a BALUN, read more about them in Tech. library or Blog by Danny Horvat, N4EXA / E73M.
