I'm looking for any paper or article that compares performance of 70cm and 2M antennas in attic environments. Preferably where multiple antennas were tested in the same location in the same attic area. I'm particularly interested in antennas such as the Arrow, eggbeater, a typical turnstile, Texas Potato Masher, quadrifiler type, the newer Cantenna, a ground plane, etc. Can anyone help me out?
