GENERAL DESCRIPTION | |
The vertically polarized log-periodic dipole antenna has a narrow, low-angle elevation plane pattern, designed for medium and long range communications. The antenna should be used with a ground mat for improved low angle performance. The vertical log-periodic antenna is characterised by a radiation pattern that is essentially constant at all frequencies. The antenna comprises a curtain of dipoles insulated into sections and suspended from a support mast. The vertical log-periodic antenna is designed for direct connection to a 300 ohm balanced open wire feeder or a 50 ohm coaxial line with a balun transformer. |
