Hello, 

I need to solve my problem on low bands; 160, 80 and 40m with one antenna. 

These are my possible solutions (which is better according to you antenna/
tuner knowledgeable people).
The antenna will be used primary for contest.

1. Inverted L (15m + 25m) with radials, feeding with coaxial cable and
CG-3000 in feedpoint 
2. Dipole (2 x 20m), via 450 ohm open line and MFJ-974HB, on 160m the
antenna will be used like T vertical and ground (@20m)
3. Dipole (2 x 40m), via 450 ohm open line and MFJ-974HB (@20m)
4. Inverted L (15m + 25m) with radials, via 450 ohm open line and MFJ-974HB 

*What's the behave of solution 2. and 3. against halfwave dipole feed via
50ohm coax on 40 respective 80m with same height, @20m? 

Thank You for all answers/ suggestions.
