Receiver sare a Tecsun pl-660 and a RTL-SDR I'm experimenting with. I have 2 antennas that I trade off with. The Longwire is a 70' copper strand with a 9:1 balun and 8' ground. The Dipole is a G5RV design at 51' each side for 102' total that I installed about 2 days ago. Both antennas are coated with no bare wire showing. At present they are both strung along a 5' wrought iron fence about 100' long. Both feed lines are presently laying across the yard until I can get them underground and lawnmower proof. In my previous residence I strung these same antennas along a wood fence. I get good performance from both but I'm always looking for even better performance. Will stringing these higher in the trees about 10-20 ' make a huge difference? Or maybe stringing them in the attic which will give me about the same height. I've got several acres to play with. Does stringing along the metal fence compromise performance? I honestly can't tell a lot of difference from the wood fence configuration at the old house. Before I go buying more feed line and stringing wire in trees or climbing in the attic I want to get a rough idea of what I can expect. I'm still learning this stuff so any and all ideas, advice and recommendations are appreciated.
