Bilal Isotron Antennas

Isotron antennas, designed and manufactured by the Bilal Company, employ a unique new embodiment of a full-size harmonic antenna which permits the radio amateur who has limited space to get on the air from an apartment, condominium, mobile home, or other space-limited environments, There are no compromises in matching or tuning Isotron antennas to your transmitter. This unique design allows direct feed with standard coaxial cable and does away with the need for radiais.

How is it that an eighty-meter antenna, for example, can be only four feet tall, eighteen inches deep, sixteen inches wide, and weigh a mere eight pounds... yet perform as well as a full-size antenna? Bilal claims that the answer is in research and development. Isotron antennas were five years in development and testing, and now are available in B0-, 40-, and 20-meter models.
