This is a reading from my RigExpert AA-35 ZOOM of my EFHW 40-10 inverted L with radials, and feedpoint 2 feet above the ground. Any thoughts as to how I can tune or move this antenna to get the lowest SWR in the 40, 20 and 15 meter bands? Thanks.

An update: I disconnected the ground lug on the box and moved the feed point up to 10 ft. Big difference. Hope to make more of a difference by increasing the antenna length.

Yet Another Update: Connected a 10 foot ground wire to the radial plate and got slightly better results (in green). If I ever care about 30 meters, I'll disconnect the ground. enter image description here

And yet another update. Extended my antenna by 2.5 feet and get the following (red is longer wire, green is shorter wire):
enter image description here

Final update: Antenna is in its "final" state, spliced with PosiLock connector and crimped with an aluminum sleeve at the end. 10 meters is a compromise for better SWR elsewhere.
