Hi!
Getting decent quality 50ohm cable is becoming really expensive over here in
Africa, and I have a few hundred yards of computer coax left unused from the
thin Ethernet days.
It's built really well, multistrand core, with dense shielding but it's 70
Ohm rated.  I've tried it out on my mic as a 15 foot extension cord (Plus
the ten feet of 50 Ohm on my GBullet -when it had Astatic 127 innards-) and
it seemed OK. 
Any comment about why / why not to use it up? I'm gigging, not recording.

Best Regards  Geoff Atkins

According to an acquaintance who manages a large music  store, a well known 
cable manufacturer did some homework on  the subject of length vs signal 
loss in Hi-Z applications.  They found in  some applications at 20 feet the

signal deterioration becomes unacceptable.  .....clip....... your cable
should be no more than 18' 7"  (according to the above mentioned
manufacturer).  At the time, this company was indeed selling cables of 18.5
feet, looking at current offerings this is no longer the case.  My guess is
that this was a marketing decision, that they lost sales to those offering a
20  or 21 foot cable.  For critical recording purposes the cable should be
much  shorter, maybe 10 feet.....clip.....
