Your suggestion is appreciated, but construction of an FSL requires a lot of diverse skills like PVC pipe gluing, Litz wire coil wrapping and high wattage soldering, not to mention the superglue-stabilized ferrite assemblies and waterproofed variable cap. The supply chain for the components is also pretty convoluted, including Russian surplus ferrite rods from the Ukraine, Litz wire from China and the variable cap from the USA. The tricky supply chain, painstaking construction and high cost components have probably all contributed to the rarity and high demand for the antennas.
