"My operation would be portable with a pushup pole in a field or near trees (support). My priority is less complexity."
I think you may have defined?what you already have as the best solution. You will be portable?with a push up pole and your priority is less complexity, so leave the tuner and the ladder line dipole and just pack the small segmented dipole. You can lower it and add or remove segments and push it right back up in a small amount of time and get consistent results without having to pack a tuner. Sometimes the simplest solution is also the least complex and easiest to manage in a portable situation.
