A while ago, when I did new cables for the radio and transponder on my Fly Baby, I used the traditional RG-58U coaxial cable.
Earlier this year, I redid the radio antenna cables. Saw that RG-400 was now the standard, so I bought some.
This weekend I was working on a non-antenna project where I thought some coaxial cable would be an easy way to achieve some shielding. Figured I'd use up some of my old RG-58 instead of my fancy new RG-400.
Stripped the end of the RG-58...and realized the difference. The picture shows the RG-58 with a black outer layer, and the RG-400's copper-colored.
These two cables were stripped with the same tool. Note how much braid is on the RG-58 vs. the RG-400.
Probably at the wavelengths associated with aircraft comms the '58 is adequate. But I SURE like the shielding on the RG-400.
Now, this might be a characteristic of the particular vendor that made the RG-58; possibly coax from another site would be better. RG-58 and BNC connectors are used a lot in the computer world.
For my airplane? The -400, thank you....
