There is no such thing as the “perfect” coax. Everything depends on the application.

In this video I go through the coax I use for:
- patch leads
- portable operation
- permanent HF installations
- direct-bury runs
- low-loss feeder
- hardline

We also discuss:
- coax loss in the real world
- why 3 dB isn’t always a disaster
- reading coax spec sheets
- bend radius and durability
- branded vs unbranded coax
- connector losses
- HF vs VHF/UHF considerations

Featuring discussion on:
- Messi & Paoloni
- Ultraflex 7
- Hyperflex / ExtraFlex Bury
- Ecoflex 15
- LDF4-50 hardline
- RG58
- RG213

The goal here is practical engineering - not internet mythology.
