My back garden is very small - about 500sqft. I also live near an AM transmitter and requires an AM filter. I would appreciate some general tips on the best approach to receiving HF signals (Ham and Shortwave Radio) in such a small space.
I use an RTL-SDR with a Ham-It-Up converter v1.3 and a Raspberry Pi.
What kind of wire antenna setup would someone suggest for such a small space? I current have a signal wire (speaker wire) coming out of a window about 10ft AGL going to the top of a shed that is about 8ft AGL. I use NooElec's "Balun" with the wire going into one hole, and the other going to the Raspberry Pi's ground. I was thinking of running some speaker wire around the perimeter of the garden, with each end of the wire going to each hole of the Balun. Would that help?
Given my small height AGL I have, and the small size of the garden, I can't really do anything nice at all I don't think :(
I tried to increase the length of the above wire by twisting some more wire to the shed-end, and walk around the garden with the slack. I found that I got more noise with only the original piece of wire. More noise is generally a good thing for reception, as it means more signal is entering the device, right? Or am I totally off base?
Any further tips would be appreciated.
