Suitable for commercial and ham transmission and reception, these Log Periodic antennas offer high gain over a wide frequency range. Used by MOD and other commercial users, they combine directivity with excellent signal pulling ability, through the well established Log Periodic design. These antennas are capable of transmitting on all amateur bands from 6 metres to 23-centimetres with up to 500 watts of RF power, but may also be used for Wide-band scanning receivers, VHF/UHF television, FM broadcast, Aviation, Government communications, and business radio! The antenna has an SWR of less than 2.0:1 across their entire range of operation. The Create log-periodic's uses a specially shaped aluminium boom that allows for movement of the phasing line. Additionally, distortions in the vertical and horizontal planes have been minimised so adjustment of the element alignment is unnecessary. Create log-periodic antennas are very easy to assemble when compared to other log-periodic designs.
