Practical answer: VHF/UHF mast placement and cable routing affect pattern, match, noise, wind load, and safety; the antenna needs controlled separation from metal and other radiators.
What changes on the air
A mast, roof edge, second antenna, solar wiring, or cable routed through the element field can distort a pattern that looked clean in free space.
Plan the installation
- Follow antenna-specific separation.
- Route coax down the intended side and strain-relieve it.
- Cross other conductors at right angles when needed.
- Recheck SWR after final mounting.
Common mistakes
- Taping coax along a Yagi element.
- Mounting multiple antennas without separation.
- Changing final routing after the acceptance test.
