Didn’t you get the memo regarding Maine is now closed to any new Amateur stations?  Thought it was full up!

Ref. Fresnel zone - looks real bad :)

This is going to be my personal Remote Contest station! I plan to be contesting from this new qth starting in 2020 but will be QRV by mid 2019 for testing.
> This qth is anywhere between 1-3 miles from the ocean or the bay, it sits on a high plateau 150’ asl thats slopes in all directions to saltwater (peninsula) except N/NW. The property has a saltwater river and marsh that runs the perimeter from south to north favoring the NE direction,  the marsh is only 50-100' wide and 1500-2000’ away from the property. The land has a gradual slope to the marsh.
