What do you have handy?  How nutty are you?

If you have 50 ft of something, give it a try.

I'm assuming you can try it easily, for example by tossing the cable out a 
window rather than going through all the effort of making a neat installation.

One of the GPS manufacturers suggests using RG-6 even though it's 75 ohms 
rather than 50.  The idea is that the low(er) loss at 1.4 GHz more than 
compensates for the impedance mismatch.  RG-6 is cable TV gear.  You can get 
it cheap.


My antenna is inside my junk room.  I'm using 25 ft of LMR-???.  It's right 
on the edge of being good enough.  My Z3801A runs out of satellites 
occasionally (once or twice per week).

What do you want to monitor?  Do you like programming?

The specs are readily available.  With a bit of hacking you can collect 
whatever info you want then feed it to your favorite graphing program.  I use 
gnuplot.
