The present antenna system includes a balun for coupling an antenna to a feed line. The balun has at least two transmission line transformers, such that the transmission line transformers are coupled in parallel at their inputs with the feedline, and coupled in series at their outputs with the antenna. At least one of the transmission line transformers maintained by the balun is fabricated so that it has reduced power dissipation properties, and reduced electromagnetic stress handling properties with respect to the other transmission line transformers. Such considerations reduce fabrication time, waste of material, and the cost of the balun.
