This experiment consisted of using a Chameleon Hybrid Portable HF Antenna the counterpoise was placed in the Potomac River for the in water experiment and taken out of the out of the water experiment. ** update apparently I connected the counterpoise to the radiator of the antenna** I will have to redo this experiment again.  I made a quick internet search on water propagation experiments and found this document Radio-Wave Propagation Measurements over Sea Water

I haven’t used the record feature of the Icom 7100 too much but it wants to separate the transmit and receiver signals so hear is the unedited record

I worked a POTA station with two parks

 And I was able to get up with N4AED in Wendell and he had a nice strong signal on 40 meters

  1. Icom 7100
  2. Chameleon Portable HF Antenna CHA HYBRID Micro
  3. Cha Spike Mount
  4. Bioenno Power 12V 20Ah 240 Watt-hours Lithium Iron Phosphate Battery
