This combination consists of three devices:
 
Receive gain:
1.8 MHz < -77 dB
3.8 MHz < -81 dB
7.1 MHz < -81 dB
14.15 MHz = -75 dB
21.2 MHz = -67 dB
28.4 MHz = – 51 dB
50 MHz = -38 dB
70 MHz = -27 dB
88 MHz= -17 dB
144 – 148 MHz = +25 dB, NF=0.7 dB, Input RL -11dB, IP3out > 37 dBm
288 MHz = -30 dB
296 MHz = -31 dB
432.1 MHz = -22 dB
440 MHz = -20 dB
Power consumption +12 V, 220 mA
 
Transmit:
Input RL: <= -37 dB, Insertion loss: 0.04 dB
Maximum power input at SWR: 
1:1 = 1500 W; 1:1.5 = 1000 W; 1:2 = 750 W; 1:3 = 500 W
