Important items in cable selection:

Impedance: 50 ohm. Hence RG58 rather than RG59.
Signal loss per foot: Lower is better. 3dB of loss = half your signal.
Shielding braid: 100% is perfect. 95% is acceptable. 
Center conductor: Must be stranded! Solid conductor will fatigue and
    break in a high-vibration environment. 
Weight: Bigger, heavier cable typically has less signal loss. 

For the comparatively short lengths of coax we use in aircraft, signal loss is
not a big issue. Thus I'd suggest RG8X (Belden 9258) coax. Don't forget to
order the proper connectors for whatever cable you choose. 

Since coax cables are a radio item, not an aircraft or hardware item, I'd
recommend buying from a radio store such as HAM RADIO OUTLET. (800)854-6046.
They ship from the store nearest you.
