You are totally correct re: theoretical gain...usually, it works best for me...am getting a bid to install my rotator/ hex beam...playing with nearly nothing is really fun for me...just finishing a Peanut Whistle 2/Sony 7600 rig with my PAR Trail Friendly 40/20/10 "hip pocket" rig (with TX batt extra)...if you hear a low, crummy fist on 7.040, it may be me...
