Have been out of ham radio for 30 years – just getting back in. Put up the EF-Quad and was surprised to find that the SWR on 40, 20 and 15 was no higher than 1.3 at both ends of the bands – pretty amazing. However, on 10 I have 2.0 at 2800 and 1.7 at 28300. Since I am only running 15 watts I would like to get this a little lower. I am nervous about cutting the stub as I am afraid I might make things worse instead of better. Can anyone tell me if I should cut the stub and by @ how much in each increment.
