This directional log-periodic dipole array (LPDA-A0066) is primarily designed for monitoring applications. It covers a frequency band of 5 to 30 MHz with a maximum gain of 5.5 dBi. The polarisation is manually adjustable between vertical and horizontal without lowering the mast This antenna is supplied with a boom that breaks into three sections and all the elements can be removed and stored in a roll-up canvas bag for compact storage (elements longer than 3 m will be split). The antenna can be assembled and erected within 60 min by four people.
