 I recently stopped at a neighborhood house to ask the occupant a
 question about the "antenna farm" in his backyard.  He has a tower
 with an array and three long wire antennas. I was hoping he might help
 me figure out how to use coax and a lightning arrestor to connect my
 old SW radios to a random length longwire antenna.
