system. If it is installed at a base site with AC power, either use a self-recharging battery-powered system (such as a
solar-charged battery) or connect the power terminals to a clean 12-volt bench power supply.
The SG-230 must be connected directly to the RF ground, which was covered earlier
in this user (Remember - the RF ground is the other half of your antenna). As was
described in that section, the connection between the ground cable and the ground (often a
bolt) must make a solid physical and electrical connection. Then it must be sealed with
spray paint or silicone bathroom caulking. Otherwise, one interesting and important rule is that your RF ground
must be larger (area-wise) than your antenna. This will probably occur naturally with base stations, but it can often
require quite a bit of work with mobile, marine, and airborne installations.
