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.
Time to start playing! Interface
the other end of the coax feed
with your radio and enjoy the
benefits of a broadband
directional antenna!
