I'm trying to receive only in the below 30mhz space. I have a long piece of wire (currently 71 ft), a nooelec 9:1 balun or unun (depending on who you ask) and an SDR.
I want to set up an end fed antenna, but I'm not really sure where to put it. I could maybe go from a second story window to a tree, but would the drop from the antenna into the house (to the balun) be considered as part of the length of the antenna? Does it matter?
I also considered chucking the wire over the peak of my roof and running the wire inside down the side of my house. Would that work?
Also what do people use for isolators? I see them in the diagrams and YouTube videos. I think I get the purpose, but what are they?
