[Collins] 302C-3 wattmeter

[Dave Brown]

I understand these wattmetters were originally supplied with a length 
of cable (4 wire screened) exiting through the hole in the back of the 
indicator unit case to connect to the coupler unit.  The 302C-3 manual 
mentions that the coupler and indicator should be separated by no more 
than 5 feet, so presumably the supplied 4 wire screened cable was 5 
feet long. Can anyone confirm this?

I don't see the reason for this seemingly very short distance 
limitation-is anyone successfully using one of these wattmeters with 
significantly more than five feet separation?

I'm putting one of these meters back together (mil version- 
OD4/GRC159(V)) after having the case repainted. Was surprised to find 
the case is actually fibreglass and not steel, as I had assumed.   In 
this one, the coupler was mounted directly on the back of the 
indicator unit and the connecting cable is only  2 or 3 inches long.

So, I'm considering whether I should mount a suitable multiway 
connector on the rear panel (or maybe use a cable mounted connector) 
to permit use of a plug/socket arangement. This will allow the coupler 
to be be easily separated from the indicator and located some distance 
away if required. Any suggestions as to what plug/socket type I should 
use to retain some degree of consideration for the original design?
