If the kit is not to be mounted in an enclosure, go ahead and install the 4 rubber feet to the bottom corners of the board where the holes are located. This prevents shorts from metal surfaces and protects tabletops, etc from damage from the circuit board. Congratulations, you have completed assembly or your Active Antenna kit! ActiveAntenna20191111 Copyright Pacific Antenna 2019... - Page 8 Usage Use a bnc adapter or cable to attach the active antenna to a receiver. If attaching to a transceiver, use care not to transmit into the active antenna as doing so will likely cause damage. Turn on your receiver and tune to the band of interest. Press the power switch on the active antenna and you should hear a significant increase in background noise and possibly signals.
