Recently they moved their operations office to a new building on the ramp to be closer to the aircraft. This building is one of the first things an arriving passenger would see. We could not put the antenna on the roof! The ICOM IC-A110E, which was used to communicate to the aircraft, was to be installed in the communication building some 500 meters away and controlled remotely from the ramp office.
At first we considered using a Radio Over Internet Protocol (ROIP) to do this. This option was quickly discarded due to the high cost.
Mobile & Marine Systems Ltd designed a simple analogue system using 4-wire 600-Ohm connection. Both locations already had ample copper pairs and it was an easy job to link them together in the main distribution room. A two wire link could have been used but we choose to go with a 4-wire to minimize the possibility of cross talk.
Once this was done and tested we attached an ICOM OPC-871 Aviation headset adapter to the ICOM A110E. This is normally used to connect the radio to a Dick Clarke headset. We modified the jacks to ¼ inch size. These were used to connect the radio to a CPI Communications Inc. TTP1 Remote controller. Using in-band signaling the CPI TR10 remote in the operations office is able to monitor and talk to the aircraft 50Km or more out. This is especially important to ensure a quick turnaround once the aircraft has landed.
We have used CPI remote products for many years both as DC remote controllers and Tone remotes. This is the first time we have used it in an Air to Ground setup. Once installed the system has been 100% reliable.
