So gently getting back to the topic of the original post which was: Getting thoughts on relatively simple and relatively inexpensive portable 160 m antenna, potentially deployable by one person, that allows for flexibility and somewhat predictable tuning for use on modest Dxpeds or rare

The plan is to develop a simple, relatively inexpensive, relatively light weight and shippable/airline transportable 160 antenna kit for one man quick deployment for modest DXpeditions or contributed for use by resident hams in rare-ish (for 160 m) locations.The ability to make adjustments to
