This application will assist you in designing Super Scanner antennas. This antenna beams into three quadrants without the use of a rotator. By using relays, a single feed line could be switched to 1 of 3 elements or to all for an omni position.

The coax jumpers made the other 2 unactive elements appear to be longer and act as reflectors. Later versions grounded the inactive elements through a tuned capacitance/inductance circuit. I found that the jumpers work better at times when made of 75 ohm coax.

This antenna is recommended for advanced antenna builders only as it is VERY sensitive to element length and spacing changes. Some adjusting will probably be required. This antenna and the name SuperScanner have patents and trademark restrictions.
