Page 2: Assembling Manual
1.1. Introduction and Description This manual explains the assembling of the ACOM LS86 HF Log-Periodic Antenna. The LS86 is a directional wideband antenna that covers the HF spectrum between 14 and 30 MHz continuously. It can be used with the full legal power of 1500W continuously or 3000W PEP. - Page 3 The first step to installation is to fully read this manual. Then, carefully inspect the shipping cartons for any physical damage. ACOM ships antennas in highly protected containers, but it cannot assure that mistreatment by shippers will not occur. If there is any such damage, notify your ACOM dealer immediately. Failure to do so may invalidate your warranty.
