My first thought about “oomphing” that FM signal out across 20+ acres:
How about “oomphing” the antenna? 20+ acres should mean the neighbors aren’t exactly next door to complain.
What’s the layout and where are you in it?
In the center? What about a 5/8 wave groundplane vertical? Or maybe a 2-element collinear folded dipole?
At an end, or a corner? How about a “Flying Vee”? Maybe two fed side-by-side to cover a larger spread? In the middle of a long, narrow lot? How about two Flying Vees back to back? See “Single element beam antennas for Part 15 FM” in the Part15.US Library.
Hey, it’s a thought…
By the way, RadioheadC, thanks. I thought that Part 15 FM used to have a 100mW/1meter standard. Apparently I’m not the only one.
