My new favorite HF antenna is the 1/4 Wave HF Vertical DX Antenna with 2 Elevated Radials.
It is NOT the most portable antenna (an EFHW wins there) but it is the easiest HF antenna to construct!
It is easier to construct, install, and tune than even the basic dipole antenna!
No toroids required. No tuner required! No doubts about whether the transformer (in case of EFHW antennas) is well-built and trouble-free.
Things needed
Wire lugs * 2
1/4 wire elements (~5 meters for 20m) * 3 - Polycab 0.5 sq mm or thicker
Heat shrink tubing
SO-239 chassis mount connector * 1
Decathlon fishing pole (5m long) - 1200 INR
Twist ties - always helpful ;)

Results
Within less than 24 hours of WSPR'ing from a 1st-floor balcony with ~1W RF output:

It appears to be quite excellent for DX'ing!
Approximate propagation conditions:
