[Antennaware] T-match question

[Bengt via Antennaware]

Hi,
Trying to decide on which T-match to use for a 144 MHz Yagi. K1FO is 
using a 4:1 balun for a 200 ohm T-match setting while KK1CW is using a 
1:1 balun for a 50 ohm T-match setting. Pros and cons? Is one easier to 
adjust than the other? And has anyone info regarding dimensions for a 
144 MHz hairpin stub for a split dipole to be fed with a 1:1 50 ohm 
balun?
