Thank you BMO. My thoughts were (are) if you didn't know what a fiver was you probably couldn't have helped much anyway so why sweat the terminology? If you did know what was meant you have helped. (Although I have to admit that Tarheel on a roof could have gone way off base LOL). In any event, FWIW (that's: For What It's Worth if you didn't know), the Tarheel on my fiver roof works great! I have no problems tuning and seem to get all the replies I need. We are now parked in a resort near Tampa/Orlando and the thing is just working!. I'm planning on installing an MFJ-1797 on a RV tilt over ladder mount soon and hope that it will provide some greater efficiency but not because I am at all unhappy with the Tarheel performance. Thanks!
