Often it is impractical to use centre loading. Assume I have an existing 20 m high vertical. Take a wooden pole, 10 m high. Put a loading coil at top of it. Place the wooden pole 1-2 m from the vertical. Connect the base of the vertical to one end of the loading coil. The other end of the coil goes to the feed point via a vertically oriented downlead wire/tubing. This technique is well known as linear loading disregarding the loading coil. Would it be worth a try or is it something I have missed? 73 Christer SM6PXJ
