Hi, My new home was constructed with steel shingles that have a fifty year warranty. While I'm happy to have a great roofing system, I'm a bit in the dark on the effect this will have on antennas that are mast-mounted off my roof. I wouldn't put a dipole going over my roof -- I'm sure the shingles would be terrible for that type of antenna. I'm wondering if there's any kind of antenna (a vertical perhaps) that might work well with the metal roof as a counterpoise? Any thoughts on what kind of antenna (HF) I can get on the roof that might utilize this unique aspect of my home? Or - should I avoid all roof mounts and just stick to putting something up on a mast in my backyard. Right now I'm running a Buckmaster 7 bander about 30 feet from my house, strung up on some low bushes and cactus and I need to get it off the ground. (Holes dug, poles/masts coming).
