STANDARD HOOK-UP

Normal applications are well suited by the default performance of the unit without the need for cumbersome reflective elements. The standard wiring configuration is simply to use the Logi as the complete antenna and merely add a means of connection for your radio. The easiest method to interface your antenna and radio is through the use of a coaxial cable with a pre-mounted connector. Standard RG-58 and a BNC connector are often used by ‘scanner buffs’ to quickly and easily monitor the airwaves. Other types of coaxial cable such as RG-142, .141 and .085 semi-rigid will also provide you with a good low loss connection as well as excellent high frequency characteristics.

Let’s take a look at the circuit board for a moment to become more familiar with its layout. The bottom side is the ‘ground’ connection and is labeled with the designers call sign “WA5VJB”. Notice that the via (the small plated through hole) near the narrow front of the board is not directly connected to the center trace on the bottom side. It is directly connect on the top side however.
