Radial=Counterpoise,usually several radials required if buried up to 120! but only one counterpoise so to be effective it has to be resonated-if short add inductance,could use ant tuning coil as suggested but then very unbalanced whole tunig system "up in the air to RF".so best to divide inductance to balance and make bottom ant coil near earth potential.Re elevated radials very effective on 80m at min 10 feet! so what about 136?Re drum transmission line -no point!line only looks like s/c so would not help but if elevated and strung out would mave shortened radial,but would need to be 300/400 feet long.Re 3 I agree. Hope all this helps 73 laurie G3AQC..
