RF amplifiers installed for PEM indoor antennas

A mini circuits amplifier was placed on the following RF signals going into the PEM QUAD I&Q Demodulator Chassis:

Cable PEM_CS_Radio_Ebay_45MHZ (AMP1)

Cable  PEM_SPQ_PWR_HAM2-3_2 (AMP2)

Cable  PEM CS_Radio_Ebay_9MHz (AMP3)

Cable  PEM SPQ_PWR_HAM2-3_1 (AMP4)

The cables were re-routed from the demodulator chassis to the network rack (next to the PEM/OAF Rack). Four mini circuits amplifiers ZHL-1A+ were monted on a rack tray. A 5 dB attenuator was installed at the output of each amplifier.

Amplifiers are being powered by a DC power supply.
