like a connection to your boiler, then BX is
acceptable.

want to handle RG-58 with 250V on the shield.If you do this, use
triax cable and ground the outter shield, and make sure the breaker can
interrupt the fault current (if the fault currrent is in the
s, or even tens of
Amps then this would not be a good idea).

Yuri,
Another suggestion would be to look for a low power GPS; I can't image
with all the GPSs out there in all those cell phones, that they all take
40mA or more. If you find one that does have low power, then locate it
at the antenna and then you won't need an active a
232 - bluetooth
converter and get the controller side of the bluetooth closer to the antenna
side.
