The log-periodic is successfully used over a narrower range, typically from about 50 MHz to about 250 MHz in the form of common TV antennas. These arrays are referred to as "self-scaling" antennas, that is, they are NOT frequency sensitve, and as such, offer a good match to a fixed impedance feedline like ordinary coax over thier entire range. Refer to W6SAI's Radio Handbook for designs spanning 140 to 450 MHz. If you need more details, let me know. Good luck es 73 de Alex, AI2Q, Freeport, Long Island >>AR>>
