This combination consists of three devices:

Receive gain:
7.1 MHz < -59 dB
14.15 MHz = -41 dB
21.2 MHz = -30 dB
28.4 MHz = - 20 dB
50 MHz =+26.6dB, NF=0.8 dB, Input RL-10dB, IP3out > 36 dBm
51 MHz =+26.6dB, NF=0.8 dB, Input RL-10dB, IP3out > 36 dBm
52 MHz =+26.7dB, NF=0.8 dB, Input RL-12dB, IP3out > 36 dBm
54 MHz =+26.9dB, NF=0.8 dB, Input RL-16dB, IP3out > 36 dBm
Harmonics and interfering signals:
70.2 MHz = -6 dB
88 MHz= -27 dB
98 MHz= -35 dB
108 MHz= -40 dB
144.1 MHz = -42 dB
Power consumption +12 V, 220 mA
Input RL: <= -40 dB, Insertion loss: 0.03 dB
Maximum power input at SWR: 
1:1 = 1500 W; 1:1.5 = 1100 W; 1:2 = 800 W; 1:3 = 600 W
