[ICOM] G5RV Dipole

[c-hawley at uiuc.edu]

Actually, I think this experience speaks more for QRP than 
it does for the G5RV. There is no doubt that a shortened 
antenna is not as efficient...all else equal. The power lost 
over a half wave dipole is probably not noticed under most 
conditions. Sometimes 5 watts is almost as strong sounding 
as 100 watts if you don't look at the S meter. While there 
is a lot of carping about the G5RV, I would say that anyone 
could convert their dipole to a G5RV configuration and not 
mention it and receive excellent signal reports. Same goes 
for the Carolina Windom. A friend used one for a year before 
he told anyone...
But, if you have the room and want to do the best you can, a 
full size dipole is probably a better idea. I can get up 
about 200 feet and it seems to do pretty well as an all band 
antenna. If I only had 100 feet up, I would tune the feed 
line as a top loaded vertical on 160M.
