K3 with KAT3 and KXV3
Figure 4 shows the antenna possibilities with both the KAT3 and KXV3 installed. The main receiver can use
ANT 1, 2, or RX ANT IN. The sub receiver can either share the main receiver’s RF source, or use its AUX RF
input. The latter can be eitherthe non-transmit KAT3 antenna or the AUX RF BNC connector, as described
earlier. In either case, the sub receiver’s antenna must be isolated from the transmitting antenna.
