[ICOM] Question abt 746 pro and G5RV combo

[Larry Winslow]

Take a look at the B&W broadband folded dipole. 
The 90' one will tune 80 thru 10 with no problem 
- the auto-tuner of my IC-765 handles every ham 
band.. I have one and have never regretted it. 
Mine is down right now as I lost the tree I had 
one end attached to but I'm about to put it back up.

R&L electronics has an ad in latest QST for the 
antenna at $199 which is way below B&W's price.
