I absolutely agree with Tim. 10 feet of RG-58 coax isn't going to mean
squat for loss on either 2 or 440. The only difficulty I see is that 10
feet doesn't get YOU too far out of the picture to make a difference in the
VSWR readings, especially on 2 meters. Lessee now, 2 meters is about 6
feet, so you are much less than 2 wavelengths away from what you are trying
to measure. If you are just looking for rough cut, it may not be too bad,
but if you are looking for some fine grain detail, I'd get a bit further
away -- like 3 or 4 wavelengths if you have the space.

Hi,

I only need about 10 feet of cable to "test" some antennas
I am going to build this weekend. It is for 2 meters and 440.
Should I just use rg 58?

You are between a rock and a 'hard place' as both RG-6 and RG-58 will
cause incorrect readings on your SWR meter.
10 feet of good quality RG58 shouldn't make too much difference,
particularly on 2 meters, but even 70cm should be OK.
