I have been using LMR-600 UF for 15+ years. Its great. I no longer worry about coax loss for 2m and 440. My runs are 100 feet. I work EME with a Single yagis.

Hello: New to satellite communication I plan to construct a fixed station to work satellites.
I am looking to identify best type of coaxial cable to run from my VHF/UHF antennas around az/el rotors to the preamplifier (located on the fixed mast/support).
Most important coaxial cable requirements include:
Highly Flexible (in upper midwest climate: temperatures range from �15 deg to +100 degrees F) in Repeated (continuous) flexing Low Loss (while super flex Heliax would be my preference, it�s not designed for repeated flexing this application sees Full shielding (preserve S/N and overall system noise figure).
I can compare the loss values from manufacturer data sheets; my main interest here is to learn what type of cable has withstood the repeated (continuous) flexing required to work satellites?
What cable type do you recommend based on your experience? Thank you 73,
Heliax Superflex? Times Microwave LMR-600UF? EcoFlex 15 Plus? Belden 9913Flex? Something else?
