My Shortened End Fed Antenna is Performing Well on 20m!

My End Fed Half Wave Dipole Antenna for 40-10m was not performing well as I have space limitation and it was a very compromised mounting. VU3TBU during a 40m chat suggested that I should cut the radiating element into half so that it will become a 20-10m antenna which can be mounted in a better way when there is space limitation. As I already have a 40/10m combination inverted V dipole antenna, which is functioning well, I thought that it was a very good suggestion and implemented it and had posted it a few days back. It was mounted in an an incomplete rectangular shape on the periphery of my small terrace with CPVC pipes as supports, which were 3m long. I could work K1LZ with this simple antenna.

Redundant part of the 10m long HLF 200 coaxial cable was kept as a coil in the hope of reducing common mode current on the outer surface of the coaxial shield a little bit.

Shield of the coaxial cable was grounded just before it entered my shack to reduce entry of RF radiated from the coax into the shack.

On air testing showed that the shortened EFHW was performing much better on 20m than the previous full length antenna. Only problem was that it would not resonate on 40 and 15 m now, because the radiating element has been shortened to 10m. Here are a few stations which I could receive very strong with the shortened EFHW with a total height of about 20 feet from the ground.
