Audio Wireless LPDA-P Passive Sharkfin Antenna The Audio Wireless LPDA-P (Log Periodic Dipole Array - Passive) antenna is designed to operate over very wide-band frequency range from 470 to 1150 MHz, with an impressive SWR of less than 2 for the whole operating range. (Standing Wave Ratio - that's good) It can be used with radio mic receivers to improve reception or can be used as a low power transmit antenna to boost the output power by up to 6dB. This LPDA-P is a paddle or sharkfin type antenna using a multi-layer PCB for reliability and is suitable for portable applications as well as fixed indoor or outdoor installations. It provides a directional coverage pattern with up to 6 dB of RF gain improvement over standard whip antennae.
