I have never put too much thought into my HF receive antenna, not where near the amount I have put into VHF/UHF. I have always used random wires with fair results. Right now I am using a 50 foot random wire antenna hanging maybe 25 feet above ground in a tree. I have located the antenna on a hilltop about 500 feet behind my shack and about 75 feet higher in elevation. The antenna wire is connected directly to center conductor of coax cable. Very crude, nothing fancy. I am looking for suggestions to improve my noise floor. The reason for locating the antenna 500 feet to the rear of my property is avoid mad made noise from local houses. Moving the antenna to this distance has helped much with man made noise but some still exists. Would I see any improvement in grounding the coax shield at the antenna or at the building?
