Am I supposed to support only the far end of the radiating wire for a sloper, and let the tuning stubs hang freely, or am I supposed to support the end of the main wire, and also support each of the stubs?
Another Question:
If I hang the radiating wire true vertical, do I just let the stubs hang straight down against the main wire, or am I supposed to support the tuning stubs as well as the main wire?
No need to support the stubs. As a vertical the stubs will hang in contact with the main radiator. That’s not recommended. Which antenna are you referring to?
EF-QUAD, EF-20/40 or EF-30/40?
