N4KGL Field Day Loop Antenna Refinements
On Sunday afternoon I spent some more time on my Field Day Loop. I measured it out and put the insulators at the right places. I also setup a feed point at the bottom center and the bottom corner. I made a 300 ohm jumper to the AH-4 tuner.   I have not test...

I have a good start on Parks On The Air AKA WWFF-KFF. I was able to count my NPOTA activations. This POTA program includes National and State Parks in the USA. It takes 10 contacts to activate under WWFF-KFF. It takes 44 contacts at a park to count for global WWFF awards. Lots of awards for activators and hunters.

This is a 100 ft wire loop 30 ft across by 20 ft high. The bottom wire is 10 ft above the ground. It is NVIS antenna on 40 meters and has 39 deg elevated lobes broadside on 20 meters when fed at the bottom center. It has low angle radiation on 20 through 10 meters fed a the bottom corner. The three poles are strapped to angle iron driven in 1ft in the ground. The poles will raise the loop in push-up fashion. It is designed to fit in a camp site without using trees or extending beyond the bounds of the camp site. I can use the Icom AH-4 tuner or a matching transformer with a tuner at the rig. The 300 ohm feed line and tuner can be switched from bottom center to bottom corner. I have not tested it with the AH-4 yet. Thanks to Myron WV0H for help with analysis of this antenna. Greg N4KGL
