More power via shorted dipole

I have used up all Amps in my 7Ah Gel battery.

I'm on LifePO4 battery now..

The shorted dipole works just fine.

Calculations for the shorted dipole

Usually mounted in Inverted vee configuration. Center frequenzy is 3.710MHz

My portable setup

Antennas:

Rear; homemade Windom antenna(FD-4 style)

Front; homemade shorted 80-m antenna

Both in Inverted setup.

At 80-meter they perform very much alike.
