MCS2000 remote head kit question- theoretical length limit
Posted: Sun Feb 19, 2017 8:10 pm
I have a situation where I have been asked to install a MCS2000 VHF mobile in a railroad passenger car. The folks would like the control head and speaker at the rear end of the 85 foot long car but have the rest mounted in an electrical cabinet up front at the other end.
I have two issues I am trying to work with.
1. The end of the car is cramped with a small lockable cabinet already there that is built into the exterior wall that would be able to house the control head and mic, but not the rest of the radio. The speaker would be mounted to the wall nearby but doesn't need to be secured.
2. Running the coax out from the end of the car is not the best as there is no access to the underside of the roof where the external antenna would be mounted. In the front of the car where the electrical cabinet is has open access to the roof.
I see there are 18 wires in the head and two for the speaker that would be needed to be extended. Does anyone have an educated guess on if this length would allow the head/radio function correctly? I would understand that if done the cabling would more likely be a larger AWG for less loss which I have no issue with.
Any comments or suggestions would be more than greatly appreciated, thanks.
