[time-nuts] Trimble recommends RG-59 Antenna Cable.

[SAIDJACK at aol.com]

Make sure to buy the quadrouple shielded 75 Ohms RG-6 cable from Home Depot 
 etc, it's much better than the standard single or double shielded RG-6 and 
works  wonders for GPS signals, and it's quite inexpensive.
 
Impedance mismatch loss can be neglected, and long cable runs can be  made.

Yes, I  use the regular satellite TV cable: low loss, easy to find and  
cheap.
