A better antenna for POTA activations

MyAntennas EFHW-4010-P

My favorite and most effective antenna for portable operation has been the PAR EF-MTR end-fed dipole for 20, 30 and 40 meters. That antenna is rated for a maximum power of 25 watts and is perfect for use with the IC-705.

For my more recent POTA activations with the 100W FT-891, I've used HamStiks - very much a "compromise" antenna, these whips are small but will handle the higher power of the FT-891.

But as of this morning's mail delivery, I now have a EFHW-4010-P from MyAntennas.

It is very well constructed, with a thick housing for the matching transformer and heavy-duty strain relief hardware. Also included, but not shown in the photo, is a frame upon which the antenna can be wound when not in use.

This antenna is rated at 200 watts CW/SSB (75W FT8) and is resonant on 10, 15, 20 and 40 meters. The

designer, Danny E73M, says it will operate on 12, 17 and 30 meters with a tuner. I have an LDG autotuner installed into the car along with the FT-891 and am anxious to see how the antenna performs on a variety of bands.

Time to test the antenna with a simulated POTA installation...

Armed with my trusty magnum slingshot, I launched a line high enough to haul the new antenna into a tree about 20 feet from the shack window. The 66 ft/20m antenna extends from just outside the window up into the tree without the need to bend it into an inverted V. It is a straight 66ft near-vertical, angled at about 60 degrees.

The nanoVNA-H4 shows the following overview of the antenna's SWR from 6-30MHz:

 

And the following for each of the four bands:

I'm hoping to get a chance to test the antenna this weekend at K-6552.
