Dan, The antenna is almost perfect as is! If you want to be a real "nut" about SWR you can take off about 6 mm (1/4 ") at the top of the main element and the same at the top of the stub element. This should result in 1.1 to 1 SWR at 146.0 MHz. But I don't think it would be worth the trouble. Harvey/W4TG
