Impedance rating and cable compatibility for CIT Shark Fin antennas
20 years old. Gear and prices may have changed since.
What the thread found
- The CIT Ultra-Ant antenna has a specified impedance of 75 ohms according to manufacturer specifications.
- Users have successfully operated 75 ohm antennas with 50 ohm cables without reported problems.
- Quad shield coaxial cable can be used to construct antenna cables for this antenna model.
Depends on
- The successful use of 50 ohm cables with a 75 ohm antenna is anecdotal experience rather than a tested recommendation.
- The discussion does not address potential signal quality degradation from impedance mismatch.
- No technical analysis of why mismatched impedance caused no observable problems.
